As with other venereal disease, venereal granulomas can be passed on to puppies from an infected mother. Females have several reproductive problems of their own. Statistically speaking, nearly half of the mammary tumors seen by veterinarians are benign. These benign tumors are usually small, firm lumps near the breast s nipple. They can start out feeling like a BB under the skin and rapidly grow into a rapidly growing mass.
Malignant tumors are actually in the breast tissue itself.
These tend to spread rapidly from the breasts, into the lymph system as well as the lungs. One of the best preventative measures for mammary tumors is to have females that are not breeding material spayed before their first heat cycle. By removing the incidence of drastic hormonal changes that occur during heat cycles, the studies have shown the incidence of mammary tumors to be greatly diminished. Pyometria is a uterine infection that turns deadly if left untreated and can still be fatal with proper medical intervention. This infection can of course only occur in unsprayed females since it involves the inside of the uterus itself.
