I have a 3 yr old puggle and I haven't had a problem since she was a pup. Lately for some strange reason she has been peeing in her bed both of them and pooping in the house, sometimes right after I take her out. I'm getting to the point where I am going to take her to the pound I can't take it anymore. I love her but this is ridiculous, she use to hold it for at least 8 hrs when I work. We did get a new kitten and it started being more frequent but she had accidents before the cat came. And she enjoys playing with the cat so I don't even know if that's it.

Have you had her checked for a UTI?

You need to get her checked out to ensure there is nothing medically wrong with her.
What is your schedule with her? How often do you take her for walks, and how long are they?

Talk to your vet, or maybe you aren't takeing her outside often enough. Dogs need to go every 2-4 hours.
