My little dog (chi-poodle) I think was biten on the back paw a few days ago. Her paw was sore for a day. She is fine now but, she has started to poop and pee all over the house. She goes outside with us multiple times a day. She will do her business outside but then comes in and a few minutes later will do her business in the house too! What is the deal? I thought she might be afraid since I think she was bitten but she goes anyway. She has also started to chew on her feet a lot! Drives me crazy... any suggestions?

Yes that definitely can be symptoms of stress. Why not try going o with her as frequent as you can, make it a pleasant time, playing, and a few treats, she will start to associate good times with out side. When she goes out by her self, give her lots of praise, same with when she comes back in side.

Was your dog bitten by another dog? Was she injured?

I have started going out in the grass with her and tell her she is a good girl when does her business. I think she was bitten by a wasp or some type of bug. Her paw was swollen for one day and she limped a little. The next day she was fine. I bathed her that day so maybe the warm water helped. She is fine now.
Thanks for advice!
