Purchasing puppies from a pet store is generally not recommended. The dogs in pet stores often come from "puppy mills" and were raised in poor conditions. They may have social problems and could develop serious health issues due to weak genetics or inbreeding. If you're interested in a purebred, look for a responsible breeder who socializes the dogs and may offer a pedigree or a lifetime health guarantee. You can even find some purebreds at your local animal shelter, as well as many other wonderful dogs looking for a new home and a second chance at life. you can also refer to
