What are your thoughts on mating? I've been wondering about this lately, since my girls were on heat recently, and I thought of finding them two boyfriends of their own breed for them to mate with them. But this makes me wonder... how many times should female and male dogs mate in their lifetime? I ask this because my granma had a french poodle that never mated (she wouldn't allow her because she didn't want puppies there). As the dog aged (female) she started to get sick; her ''breasts'' started swelling and changing of colour... like she had bruises all over her belly :( The vet told them it was because she never got the chance to mate!
