When looking to purchase a puppy, it's essential to choose a responsible breeder. A reputable breeder will screen their dogs for health issues, including hip dysplasia, using evaluations from the Orthopedic Foundation for Animals (OFA) or PennHIP. This commitment to health ensures that you're bringing home a puppy that has the best chance for a long, happy life. Make sure to ask for documentation and don’t hesitate to inquire about the breeder's practices.
