My male poodle tied with my rat terrier. She had her pants on and he managed to manuever aroud the tail hole. Should I abort this litter today?

Dear Mr. Frawley,

I have searched through your Q&A for an answer to my question regarding an accidental breeding but did not find an answer that I was satisfied with so I wanted to write you.

I am a relatively new breeder of rat terriers and toy poodles. My terrier bitch has been breeding with my terrier male since last Thursday, 6/25/09; and today, 6/29/09, was a day that I wanted to skip, after talking with another experienced breeder. I put the pants on the bitch and was in the process of putting the pants on the male. While I was doing this, my male poodle tied with this bitch. She had her pants on and he managed to maneuver around the tail hole. So, my question is, is this potential litter now going to have poodle genes in it? I do not want to have mixed breeding and certainly don't want dogs that carry other breeds of dogs in their genes. Should I abort this litter today? The bitch has been bred twice each day since Thursday, June 25th. I don't want to put my bitch through the pregnancy if these puppies are going to be mixed breed. Nor do I want the expense of raising these pups up until I give them away for free.

Thanks so much,
Kathy
