Curly Coat Dog

Curly coat Like all mammals, a dog's hair is primarily composed of the protein keratin. Mutations in genes responsible for encoding keratin can lead to alterations in the shape and texture of individual hairs, consequently impacting the overall appearance of the coat. One such example involves a recessive mutation in...

Recessive Hypotrichosis Dog

Recessive hypotrichosis Hypotrichosis is characterized by reduced hair growth, leading to a sparse coat or even complete hair loss. While many types of hypotrichosis are inherited dominantly, a recessive form of the condition stems from a mutation in the gene encoding serum/glucocorticoid regulated kinase family, member 3 (SGK3). Puppies with...
