I know that breeders sometimes have unplanned pregnancies, but then to my way of thinking they are the only people who should have entire animals in the first place.
I would abort unless I was advised that there was a danger to the bitch in which case I would most certainly let the pregnancy run it's course and decide then what to do.
I will be honest and say that I would pts the puppies if Mickey (Whippet) had mated with Gemma (Gordon Setter), although she is now de-sexed as she is not the best example of her breed. Because I do not believe that I could find suitable homes for a X-breed with such a high prey drive that those two breeds would create.
If Mickey had got to Tilly this time I would of gone thru with the pregnancy as it is a mating I plan to do anyway and I have 3 people waiting for that mating and I'm interested in keeping one as well. But if it had happened a couple of months a go when I had a pile of bills I probably would have taken her for injections, I wouldn't have even needed to see them in the act, just the two of them not being where they should of been and she would of been off to the vet.
I'm not saying there are not individual reasons for unplanned pregnancies to go ahead, but I guess it's the fact that people who are not showing/breeding want to keep entire animals or take on another entire animal for whatever reason and then are surprised that it happened in the first place.
Gosh people, apologies for the novel. I don't mean to shove my opinion down peoples throats I just want people to think before they take on an entire animal for whatever good intensions to go home via the vet whenever possible.
