Spaying? A sexual crime against dogs? Sorry, but that's hilarious.
is a sexual crime against dogs, not a surgical procedure that can help save a dog's life.
But I think your attitude to your dog shines through in your later posts. Starting with the grin. I think you knew that your dog would be at her fertile stage just when you left her. I think if you really didn't want to risk breeding her, you would have boarded her with someone who didn't have dogs, under the strict instructions of not walking her in peak walking times, and under strict garden supervision. And in the event that she was still mated, you would have been on here a lot sooner, in a panic, looking for the advice you needed to end the pregnancy.
What you would not
be doing, is offering a stud fee and grinning about the fact that a bitch can be pregnant by two sires at the same time. I think you saw pound signs when you realised she was pregnant. Given your "internet knowledge" you may have known about the mismate jab already, and waited just long enough before taking her to the vet so that the mismate was no longer an option, guaranteeing you puppies.
I think your main priority is your house, not the bitch's welfare. And therefore, the financial damage caused to the house by the puppies. The fact that you got lucky and she sailed through the pregnancy and birth without major complications hasn't even entered your head.
What I don't think, is that this will be your bitch's last litter, sadly.
Prove me wrong.
