Firstly, it's important to find a reputable breeder who prioritizes the health and well-being of their dogs. Look for breeders who are members of recognized Mastiff clubs, such as the Mastiff Club of America or the English Mastiff Club of America. These clubs have strict guidelines for breeding practices and can provide you with a list of responsible breeders in your area. When visiting a breeder, ask to see the parents of the puppy and their health clearances. Reputable breeders will have their dogs tested for genetic conditions such as hip and elbow dysplasia, cardiac issues, and eye problems. They should also be able to provide you with a detailed health history of the parents and the puppy. It's also important to consider the cost of owning a Mastiff. These dogs are large and can consume a lot of food, which can be expensive. They also require regular grooming and veterinary care, which can add up over time. Be prepared to budget for these expenses before making a purchase. When it comes to finding a Mastiff for sale in California, there are several options. You can search online classifieds websites such as Craigslist or PuppyFind, or visit local pet stores. However, it's important to be cautious when buying a dog from these sources, as they may not always be from reputable breeders.
