Depending on how far along she is it could be that the puppies are pushing on her bladder & bowls and she is just can't help herself, but that would be something you would need to speak to your vet about
and to a dog won't poop or pee where it sleeps, you might think about confining her while your not at home, take her out before you leave and as soon as you get back to reinforce her potty training
thanks..I hate to put her back in her crate at night and while I am at work..But I guess I have no other choice. She will see the vet august 19 and get her x rays to see how many etc and I will ask then. I appreciate your helpful answer. I hope after the puppies are born she will be back to her old self in control of her bladder and bowels.
I just hope this is all it is.. anyone else have anything to add please do. thanks again.
