What do the terms spay and euter mean?
When a dog or cat is spayed, their reproductive organs are removed while she is under anesthesia. This includes their ovaries, fallopian tubes and uterus. When a dog or cat is neutered, the testicles are removed while he is under anesthesia. Some males may have an undescended testicle, which means it is not in the scrotal sac. It is usually found in the abdomen or inguinal region through an additional incision. It is still important to have this testicle removed as it can become cancerous or diseased if it is left behind.
