Did you know it's illegal to give health advice over the internet for animals? Go to a vet.

I'm not sure if this applies to all breeds, but all females should be bred to males that are smaller than them.

I don't agree with you breeding this female at all. As you can see, a lot of people on here do not as well.

There's no need to carry on this line - regardless whether it has no floors - just because your grandfather brought the line over.
