Analysis of clinical and genetic data of limb anomalies, the dental system and cryptorchidism in the Newfoundland dog breed in St. Petersburg
The article examines clinical symptoms of limb anomalies in the Newfoundland dog breed. Other symptoms such as misalignment of teeth (skewed), undershot bite, and cryptorchidism were also looked over. Forelimb (FA) anomalies were diagnosed in two puppies at the age of 2.5-3 months; the rest of the puppies had other anomaly from birth. Cryptorchidism was found in four dogs, three had unilateral cryptorchidism, while it was unidentifiable what the fourth male had. Misalignment of teeth was in two dogs and undershot was in seven canines. The genealogy of over 600 dogs was studied and a genealogical scheme was made. The dogs were divided into 3 groups according to origin. There were cases when one animal had two pathologies. For example, one dog had cryptorchidism and undershot, and a bitch had littermate overshot and teeth displacement. The clinical symptoms were proven to be genetic disorders. Recommendations are available for breeders that wish to continue breeding these types of dogs.
