whos dogs are from petstores?

[Jessika]

All but one of the dogs I have had in my life are/were rescues. The first dog I had (I got him when I was 2) was from a friend whose "spayed" bitch had a litter. (It's rare, but it happens, though less often now than 20 years ago)

I thought that was impossible, because when they perform a spay they remove the ENTIRE uteris??
