I'd argue that Mabel never intended to get pregnant, didn't consent or request motherhood - especially not nine puppies, definitely too many for her.
I think I can count on one hand the number of times she nursed them unassisted by us. We've been rotating pups because there aren't enough producing breasts and she was bruised on the sides of breasts where puppies sucked harder and harder hoping they could make milk come out.
So her breasts engorged and we were read the internet, consulted, and applied cabbage leaves and milked her. We kept a t-shirt on her because she was clearly tender and didn't want puppies sucking (biting!).
And got to the vet today, thankfully - because she has necrotic tissue in one breast - poor Mabel! She'll be so relieved to get spayed.
With burdock and cabbage and ace bandages and prescriptions and lots and lots of rags and towels everywhere, we're going to get through.
