We owned a toy poodle once that my parents never got around to neutering when she was young. We had a backyard and no male dogs, so her becoming pregnant was not a worry. What WAS tiresome was changing her pads and diapers all the time--plus, it didn't look like much fun for her! The worst of it was, when she was older, her uterus got infected and unless I remember incorrectly, had to be removed anyway. She pulled through with no problems, and we learned our lesson. Spay early and save your dog (and you) the headache!

Does anyone know if failing to get your dog neutered at an early age is a possible cause of uterine problems later in life, or was this just a coincidence?
