If you’ve ever thought about getting a new dog, you’ve heard the arguments adopting or purchasing from a responsible breeder. But what makes a responsible breeder. One very important criteria is that the breeder does genetic testing on their breeding pairs so as not to pass on genetic disorders. In Finlandor Brazil, one in every three Brazilian Terriers carries a mutation that could lead to a skeletal disorder in puppies that doesn’t allow them to stand or walk. A new test will allow breeders to test their dogs in order to prevent this disease from ever affecting another puppy.
