But a couple in Surrey, B.C., faced a horrible experience of having to euthanize a French bulldog puppy just four days after purchasing the animal, because it turned out to be sick.
Ethan O'Reilly, a veterinary assistant at the Toronto Central Animal Clinic, says he often meets owners with sick pets bought from breeders.
"We see issues where they come in and they are not properly de-wormed or vaccinated, or they are essentially lied to," he says.
Here are some things to keep in mind to help determine the animal you're bringing home is healthy.
1. Do your research
"First and foremost, the best thing to do is look for a pet that complements your lifestyle rather than the look of the animal," O'Reilly says.
Once you've picked a breed that fits, research the health issues that breed tends to face — for example, Irish wolfhounds and Great Danes tend to suffer from bone issues. If you know the most common problems of your chosen breed, you will have a better idea of the symptoms to watch.
2. Find a reputable breeder
O'Reilly advises being "extremely cautious" when buying from breeders on websites like Kijiji — many of the young animals he sees with health issues were bought online.
But if you do choose to go with a breeder found on the internet, he suggests talking to them over the phone or even arranging a visit.
"If you don't have a good relationship with the breeder, you're not going to ensure the proper health of the animal," O'Reilly says.
He recommends looking for breeders through the Canadian Kennel Club — its members must adhere to its policies and code of ethics. The organization even provides a handy guide to finding a reputable breeder.
3. Get the proper paperwork
Sellers should be able to provide you with health certificates and records of veterinary visits. If you're buying a purebred dog, you should also get a certificate showing the animal's bloodline, O'Reilly says.
The Canadian Kennel Club also advises insisting on getting a written guarantee from the breeder when buying a purebred animal. This document covers what the compensation would be to the buyer if the dog ends up having any health problems related to its genetics.
4. Examine your potential pooch
When you meet the dog you want to buy, you should look for clues it's happy and healthy. O'Reilly recommends inspecting its eyes, ears and nose, and looking for any signs of eye or nasal leaking.
He says you should also look for classic symptoms of health problems that the breed might be prone to (which you should already know if you've done your research).
Most importantly, be ready to ask any questions about what you're seeing — and the seller should be able to answer them. "Don't be afraid to ask questions, that's the No. 1 thing," O'Reilly says. "Why are his eyes leaking? Why are the folds in his face dried out like that?"
5. Consider adopting from a shelter
Unless you're adamant on getting a puppy or a specific breed, O'Reilly suggests considering adoption.
"Shelters are great," he says. "Shelters, I promote 100 per cent."
While shelter animals are prone to certain illnesses — upper respiratory infection in cats and kennel cough in dogs — many of those problems are easily treatable.
A major advantage of adoption is that many shelters have their own veterinarians who will do a complete checkup on the animals and fully disclose any illnesses.
"Upon adopting that animal, you know what you're walking into, and if you as an owner are struggling with that issue, they wil help you," he says.
Whether you're buying from a breeder or adopting from a shelter, the biggest piece of advice, O'Reilly says, is to inform yourself and ask questions.
"If you don't know a lot about puppies, that's OK. But do your research."Suggest a correction
