Hyperandrogenism in dogs is a rare syndrome characterized by elevations of masculinizing sex hormones such as testosterone and its derivatives in the blood serum. Hyperandrogenism may occur as a result of excessive hormone production by the testes, ovaries, or the adrenal cortex. Hyperandrogenism may be symptomized by behavioral changes, abnormalities of the reproductive tract, and skin problems. Symptoms include Aggression, Stunted growth, Hair loss, Dry, brittle hair, Hyperpigmentation of the skin, and Dandruff. In females, symptoms can also include Vaginitis, Irregular estrous cycles, Prolonged anestrus, Virilization, Clitoral hypertrophy, and Abnormal sexual differentiation. In males, symptoms can include Prostatomegaly, Abnormalities of sperm morphology, and Circumanal gland hyperplasia. Hyperandrogenism may also cause Prepubertal Premature growth plate closure, resulting in the body stopping growth before reaching full size.

The increased hormones can sometimes lead to behavioural changes including aggression, but these are very variable and differ between individual dogs. Once the testicles descend and his testosterone levels begin to rise, the puppy will start to lift their leg to urinate. Males do not have a season like bitches, and once sexually mature they can breed all the time, although are at their most fertile between around 12-18 months old.
