If during a one year period from the time of transfer a qualified veterinarian reports in writing to Northern Woods American Bulldogs (NWAB) that the puppy has any proven genetic defect that substantially affects their quality of life, NWAB will replace the puppy with another puppy as soon as one is available. Your puppy is guaranteed not to have severe hip dysplasia, and if your dog should develop severe high dysplasia we have a criteria for you to follow. We will require a copy of your dogs hip x-rays and an O.F.A. reading for hip dysplasia. In fulfilling these requirements WE WILL GLADLY REPLACE YOUR PUPPY WITH A REPLACEMENT PUPPY OF YOUR CHOICE AS SOON AS ONE BECOMES AVAILABLE. The affected dog must be returned at the time of replacement.
