Amelogenesis imperfecta is characterized by defects in the enamel formation of both baby teeth and permanent teeth. Enamel formation starts before the eruption of the first teeth and there will be no subsequent repair of the enamel after eruption. The enamel of affected teeth erodes more rapidly over the years than normal enamel. The teeth of affected dogs are pitted, rough, and discolored brown. Affected teeth are often small and pointed with increased gaps. This form of amelogenesis imperfecta is relatively mild, and the affected teeth function in a nearly normal fashion. There is no treatment available for amelogenesis imperfecta, but most dogs live a normal life with mild signs.

For dogs affected with this condition, particular attention should be paid to maintaining good dental health. Dental intervention may be needed in some cases.

There are many responsibilities to consider when breeding dogs. Regardless of test results it is important that your dog is in good general health and that you are in a position to care for the puppies if new responsible owners are not found. For first time or novice breeders, advice can be found at most kennel club websites.

Amelogenesis Imperfecta (Discovered in the Italian Greyhound) is autosomal recessive meaning that two copies of the mutation are needed for disease signs to be shown. A carrier dog with one copy of the AI mutation can be safely bred with a clear dog with no copies of the AI mutation. About half of the puppies will have one copy (carriers) and half will have no copies of the AI mutation. A dog with two copies of the AI mutation can be safely bred with a clear dog. The resulting puppies will all be carriers. Puppies in a litter which is expected to contain carriers should be tested prior to breeding. Carrier to carrier matings are not advised as the resulting litter may contain affected puppies. Please note: It is possible that disease signs similar to the ones caused by the AI mutation could develop due to a different genetic or clinical cause.
