​In recent decades, pets have become more than just companions, they’ve become family members offering companionship, emotional support and unconditional love. But in recent years, a huge shift in the veterinary industry has turned that bond into a source of anguish for many guardians. The fast corporate take over of vet clinics around the world has driven up costs, leaving many guardians facing the impossible choice of either paying outrageous bills or surrendering their beloved pets.

​Even compassionate veterinarians sometimes sell their clinics to corporations due to financial pressures, burnout and the growing demands associated with running today’s animal hospitals. Many independent clinic owners face high operational costs, student debt and staffing challenges, which make it difficult to remain profitable without outside investment R13. Corporate buyers offer attractive purchase prices, simplified clinic management software and relief from administrative demands, allowing veterinarians to focus more on patient care rather than business operations R14. Corporate ownership can also provide access to advanced technology, bulk purchasing power and improved employee benefits – all advantages that small clinics often struggle to provide on their own R15. While these sales may be emotionally difficult, many caring veterinarians see it as a practical decision to ensure the clinic’s longevity and continued service to the community R16.

​The veterinary industry has undergone a drastic transformation over the past decade caused by private equity firms and major corporations buying up independent clinics. Corporate chains have taken over thousands of practices internationally, focusing on profits over affordability, quality of care and access.

Industry research shows that corporate ownership now controls more than 20% of veterinary practices in Canada alone, including more than 40% of practising veterinarians R8. In Ontario, this has created near-monopoly conditions in urban and suburban areas, driving up fees for routine services by 20 to 50% since 2020. National studies show veterinary revenue growing rapidly in recent years, with Canadians spending around 9.3 billion dollars annually on veterinary care R3.

These corporate takeovers bring in one-size-fits-all pricing that overlooks local economies, while inflation, supply problems and post-COVID demand push prices even higher. As Charmaine Brett (President & CEO of the Ontario SPCA & Humane Society) noted in a recent column, “Tariffs and inflation have pushed up the cost of supplies, which in turn has led to higher clinic fees” R1. According to Canadian research firm Abacus Data, nearly 72% of pet guardians say veterinarian fees are too high, and 34% report that vet bills have caused them stress over the past year R4.

Unfortunately, this is not just a new business trend – it’s a public health, financial and social justice crisis. Due to rising living costs and interest rates, 42% of Canadians could only pay for basic expenses for less than one month if they lost their income R2. For many pet-owning families, veterinary bills have become the breaking point.

​While provinces require veterinary practices to be owned or directed by a licensed veterinarian, corporations often blur those lines. In many cases, the corporation registers a veterinarian as the owner while the corporation dictates the pricing, staffing and operations behind the scenes. This creates a business model that technically meets provincial licensing standards, while tying the hands of veterinarians to make independent decisions R8. The Canadian Veterinary Medical Association (CVMA) has warned that corporate ownership has taken away each veterinarian’s discretion, and some report feeling pressured to meet sales quotas and up sell expensive services R9. Because current regulations haven’t been updated to deal with this situation, there are few safeguards in place to make sure that patient care is prioritized over profit.

​The human cost of these inflated prices is serious and deeply personal. The Ontario SPCA has reported a 17% increase in pet surrender requests from 2024 to 2025, with over 85% caused by the guardian’s inability to afford veterinary care R2. These are not impulsive decisions, but instead heartbreaking acts of desperation.

Luna was a loyal companion dog whose guardian, living on disability had faithfully managed her veterinary needs for years. When a urinary condition demanded surgery and specialized food, the costs proved unmanageable. “With deep compassion, he turned to us, hoping we could provide the medical support she needed and find a family able to take on her ongoing expenses,” Charmaine Brett recalled R2.
​
At humane societies, situations like these are a daily occurrence. Some are pleading for help with basic needs, while others face eviction because they can’t afford to spay or neuter their pets. One family was able to keep their home only because of the SPCA’s mobile neuter services R2. Some parents have to skip their children’s extracurricular activities to cover pet expenses, and some seniors sacrifice their own medications to prioritize their pets.

Total vet clinics in Canada – Approximately 4,400
 
Total clinics under corporate control – Approximately 1,000
 
Corporate share of general practices – Approximately 20 to 25% (and growing)
​

​The truth is that corporations secretly control many veterinary clinics that appear to be privately owned, which makes it more difficult to find out which are in fact owner-operated. In the end, the only way to know for sure is to visit each corporation’s website or ask the facility directly.

​Corporate consolidation doesn’t only affect pet guardians – it’s affecting veterinarians as well. The Canadian Veterinary Journal has reported a significant shortage of qualified veterinarians, particularly in rural and northern communities where a shortage of staff delays and limits access to health care R9.

Veterinarians blame heavy workloads, reduced control of their clinics as well as pressure to meet quotas and up sell as the main reasons for their emotional exhaustion. Many veterinarians report increasing burnout, compassion fatigue and moral stress under corporate ownership. A 2024 CVMA report found that over 60% of Canadian veterinarians are experiencing symptoms of burnout and nearly one third have considered leaving the profession entirely R9. It goes without saying that any solution to the veterinary crisis must also prioritize the wellbeing and fair treatment of veterinary professionals themselves.

​The corporate pet care model has let down so many pet lovers, however community driven alternatives are already starting to make a difference. Locally owned clinics, private, non-profit and cooperative options have the potential to restore access to affordable, compassionate and quality care.
Non-profit and cooperative veterinary clinics are already operating successfully in several regions in Canada. For example, the Toronto Humane Society’s public clinic provides low-cost preventive services and surgeries, which is funded by donations and municipal support. Cooperative models in British Columbia allow guardians to buy memberships that reduce vet visit costs and reinvest their profits into the clinic rather than lining the pockets of shareholders R10.
​
Integrating pet care into social-service systems such as food banks, housing support and mental health programs are put in place to treat pets as family, not possessions or luxuries. These models help keep pets with their families and prevent over crowding in shelters R2.

​When veterinary care becomes a force that prioritizes quantity over quality, everyone loses, especially the pets and those who love them. The growing influence of corporate chains has driven prices so high that love alone can no longer keep families together. If we all stand behind community-based clinics and fair access to treatment, we can rebuild a system rooted in compassion instead of the almighty dollar.

​In a world quick to label and judge, dogs often suffer the results of snap decisions based on looks alone. A muscular build, square head or short coat (especially black or brindle) can brand a dog as dangerous. It can lead to fear, avoidance, discrimination in adoption and even housing and legal restrictions. This tendency not only harms dogs and those who love them, but for many it closes the door to discovering their true potential for affection, loyalty, intelligence, playfulness and companionship.

Judgments rooted in appearance are almost always wrong and disregard the combination of influences that shape every canine such as genetics, environment, training and unique personalities. This parallels human prejudice where people are judged by the colour of their skin, facial features, tattoos, body type and size and even their choice of clothing. Although stereotyping is harmful, misguided and preventable, many people continue to judge one another by appearance so why would they not do the same with dogs.

​Breed profiling, the canine equivalent to racial prejudice continues in spite of evidence that proves the associated assumptions are wrong. The dog in the photo above was my boy Tala. Although many people were afraid of him due to his appearance, he was an amazing dog and not once showed any sign of aggression toward another dog or person in fact, he was amazing with puppies and was good with everyone in my classes, including children.

Greg and I adopted Tala and his littermate Atka at 7 weeks of age and took them out for plenty of socialization. Since Atka was a stunning puppy and Tala was black, Atka got all the attention and Tala was ignored. Because of this, although Tala developed a wonderful personality and temperament, he also grew up to be aloof and standoffish with new people. Had he received the same attention from strangers that his brother did, he would have become a more social adult dog. This is just one example of how judging a dog by appearance can affect it long term. To learn more about how to nurture a great temperament in your dog see our first book Blueprint To A Happy Dog R5.

Tala aka Boo & Atka aka Bubba

​Careful breed selection is important – not because certain breeds are prone to aggression but to ensure the dog’s needs are met and to match their training requirements, energy and instincts to the guardian’s lifestyle. Understanding each breed’s natural tendencies is one of the keys to bringing out the best in our dogs and preventing unwanted behaviours. We DNA-test all of our rescues, so we know which behaviours to expect and work on.

A study of over 4,000 dogs of many breeds with similar training and experience, found no significant breed-related differences in aggression toward strangers or guardians, meaning that a dog’s history is a much better predictor of aggression than appearance R2. It’s important to understand that aggression is just communication, it’s not a breed-specific trait. Every dog has the potential to bite and any breed can thrive with responsible breeding, proper training and socialization. For more information about aggression see our first book Blueprint To A Happy Dog R5.

A major problem occurs with shelter dogs when their breeds are determined by visual assessment alone. This practice is so unreliable that even experts disagree on a dog’s dominant ancestry 70% of the time R2. A dog with a broad chest, square head and cropped ears might be labelled a Pit Bull mix and immediately flagged as high-risk, despite genetic testing that could reveal a Labrador, Hound or Collie mix. This visual misdiagnosis triggers a myriad of consequences including mandatory muzzling in public or euthanasia under breed-specific legislation R4. I once had a Doberman-Golden Retriever cross that I adopted from a breeder who owned both parents and had a breeding accident. She looked like a skinny black Lab mix, and not one person ever guessed her breeds correctly.

​The American Veterinary Medical Association (AVMA) states that breed specific legislation has failed to reduce dog bite incidents in every jurisdiction studied, yet it continues because fear sells headlines R4. Meanwhile, a dog capable of therapy work, search-and-rescue or simply being an amazing companion is overlooked or dies because of a damning stereotype.

Dogs judged solely on appearance face euthanasia in shelters, breed-specific legislation that bans them from entire communities and rejection by potential adopters who fear how they look rather than who they truly are R4. Luna, for example was a square-headed shelter dog labelled a Pit Bull mix that was overlooked for months. A trainer who saw past the way she looked adopted her. She uncovered her gentle nature and intelligence and within a year, Luna earned certification as a diabetic alert dog, saving her guardian’s life repeatedly by detecting dangerous blood sugar drops. Although her appearance branded her as dangerous, her behaviour proved heroic. Stories such as Luna’s are not uncommon as the National Canine Research Council has documented dozens of marginalized dogs thriving in therapy roles in hospitals and schools, their success attributed solely to early and proper training and socialization, not genetics R4. For more information about socialization see my article entitled Socialization – Why It’s More Important Than Dog Training.

According to Greg Ceci, in order for a dog to be well rounded regardless of its breed(s), it all comes down to four basic pillars: responsible breeding, positive training, early socialization and meeting all the dogs’ needs R1. Unfortunately, many people are full of excuses as to why they are unwilling or unable to meet the requirements of these pillars. The truth is that taking shortcuts on any of the four pillars dooms the dog to a compromised temperament, emotional wellbeing and quality of life through no fault of their own R1. That said, even dogs that have been traumatized or were not properly trained or socialized, can often be rehabilitated and become trust-worthy.

Puppy buyers tend to prioritize physical traits such as fluffy coats, rare colours or designer crossbreeds over health and temperament screening. A 2022 survey of 2,000 new dog guardians showed that 68% chose their puppy based primarily on appearance, with less than 20% asking appropriate questions, meeting both parents or observing the litter R2. This obsession with appearance fuels a 2 billion dollar a year puppy mill industry that prioritizes quantity over quality and produces dogs with health issues, behaviour problems, reactivity and aggression R1.

​Another problem is that the insurance industry cashes in on this myth for monetary gain. Insurance companies either deny coverage or charge outrageous premiums for dogs with certain appearances, stating it’s a “risky breed” in spite of all the science that proves there is no correlation between appearance and bite severity in dogs bred and raised properly R4. Insurance companies also make it difficult for those who offer services such as dog training to get a fair price for liability coverage. Insurance policies are not based on science and punish dogs and those who love them for how they look.

The ASPCA’s Meet Your Match program evaluates dogs by behaviour, not looks, which results in a 90% success rate and very few returns R4. Likewise, trainers that use 100% positive, force-free methods report faster and more reliable results, especially when preventing or treating aggression, no matter the breed, proving that science and benevolent leadership are much more effective than following stereotypes. For more information about positive dog training see my article Positive Dog Training – Science | Ethics | Results.

Breed profiling mirrors the human habit of judging others by appearance, yet dogs suffer in silence when there is no one to advocate for them. Unfortunately, children often learn these biases from their parents, learning to judge a book by its cover and pass these same prejudices on to the next generation R1.

​In 1997, Kitchener, Ontario was the second city in Canada to ban Pit Bulls. My dog training facility back then was Puppy Power (now belonging to Samantha DeJong, CTB.ccs, IPDTA-CDT). We were asked to perform temperament testing in order to grandfather the Pit Bulls that were already in town and tested over 50 outstanding Pit Bulls in one day.

Before the ban I had plenty of Pit Bulls in my classes along with all the other breeds and cross breeds and never had a issue with them. I was also conducting a lot of aggression consultations, and the dogs I worked were almost never Pit Bulls. Some of the most aggressive were the smaller, under-estimated breeds that were un-socialized and poorly trained, and some were Labs and Golden Retrievers. Over the years I’ve met many of the “questionable” breeds that proved to be real sweethearts, friendly, cuddly and a joy to be around. My point is that the breed was never the issue. Aggression is caused by people, whether they breed fearful or aggressive dogs, fail to meet their needs, sufficiently train and/or socialize them from a young age, fail to protect them, neglect or abuse them. My opinion is that breedism is discrimination! I will never accept discrimination of any kind against people and I won’t accept it against dogs!

​Many people are unaware of the importance of a healthy and happy mother to the future wellbeing of her unborn pups. Mothers that experience an unusual amount of stress or anxiety during pregnancy are likely to give birth to puppies that are innately sensitive, anxious and often reactive. If the mother is emotionally stable and in good health while carrying her puppies, chances are the pups will be as well. After a puppy is born, it’s experience that shapes its behaviour and personality.

​The neonatal period of development starts at birth and lasts until the eyes and ears begin to open. During this time, the puppies are deaf and blind, they’re entirely dependent on their mother and they spend all their time nursing and sleeping. Although short, this stage still offers an opportunity to begin shaping behavior and stress resilience through calm, gentle and careful handling. Short, controlled handling sessions have been shown to improve cardiovascular health, strengthen the immune system and produce puppies that are more tolerant of stress later in life R3. While no behavioral training occurs during this stage, it is the foundation upon which trust and tolerance begins. For more information about how to prevent and treat stress in dogs see my article entitled Stress & Anxiety – Protecting Your Dog’s Health & Happiness.

​During the transitional period, the puppies begin to open their eyes and ears. They become more active, start to interact with their littermates and begin to explore their immediate surroundings. This is a short yet important stage of sensory awakening. Human contact during this stage should increase gradually and carefully. Gentle handling, exposure to subtle scents and new surfaces as well as positive interactions with people help the puppies to associate human presence with safety and comfort. On the other hand, early unpleasant experiences such as rough handling, startling events or anything more than very short separations from the mother and litter can begin to shape fear responses even at this early age R4.

​From three to seven weeks of age, puppies develop essential social skills through play with their mother and littermates – including bite inhibition, reading and using body language as well as learning to distinguish friendly interactions from conflict. Unless in the hands of a qualified puppy raiser with access to suitable dogs, puppies removed from their litter before 8 weeks can fail to develop proper dog/dog social skills, which could lead to issues down the road such as poor bite inhibition, fear, reactivity and dog-dog aggression R5. For more information about socialization see my article Socialization – Why It’s More Important Than Dog Training.

​Between 8 and 14 weeks of age, puppies are at a critical stage for bonding with people and adjusting to new environments. During this time, their brains are highly adaptable and they quickly adjust to new experiences. Pleasant exposure to a wide range of stimuli including a variety of people, animals, surfaces, sounds, vehicles, grooming tools, new environments, etc. nurtures a resilient, confident adult dog R6. However, unpleasant experiences or a lack of exposure during this period can result in deeply rooted fear and reactivity. For example, a puppy that never sees children during this stage can develop a life long fear of children. This is why both the Canadian and American Veterinary Associations urge guardians to begin socialization as early as possible. Carefully managed puppy classes, visits from safe guests, car rides and exploration of various environments are all essential activities during this time R7.

The second fear imprint period occurs during adolescence, which is anywhere from 6 to 14 months of age depending on the size of dog. It typically coincides with a surge of hormones and increasing independence. Dogs can suddenly become fearful of things they previously tolerated and behaviors such as leash reactivity or anxiety can seem to come out of nowhere.

Both fear imprint periods are normal yet require special handling and attention. Harsh corrections or forcing the dog into frightening situations can cause regression and create long-term behavioral issues. Positive training, patience, consistency and reassurance are crucial during these stages R9.

​When A Dog Reaches Sexual, Mental, Emotional & Social Maturity

As dogs reach full maturity their personalities stabilize and if they’ve had positive experiences, they are more capable of handling stress, new stimuli and social interactions with grace. However, socialization should never end at maturity.
​
Ongoing exposure to new people, suitable dogs, places and experiences helps prevent regression and keeps the dog emotionally adaptable and resilient. Dogs can learn new things at any age, however adolescents and adults are less flexible and resilient than puppies. If the dog has had traumatic experiences or lacked proper training and/or socialization early in life, behavioral rehabilitation may be necessary. While it’s always possible to improve a dog’s behavior through rehab, the earlier it receives positive social and environmental exposure, the easier it will be to prevent long-term behavior problems R12.
