Rescue Bassett Hound Pooping Inside?

I rescued a Bassett Hound from the street about 7 weeks ago. She was very malnourished and deprived of food. I have been giving her Royal Canin which has helped with her weight. The vet said she is about 1.5 - 2 years old.

My problem with her is the frequency she goes potty. She consistently poops 6-7 times a day. Recently she has started pooping in my bedroom right after I take her inside from pooping outside. She has pooped in my bedroom after doing the same thing outside for 2 straight days now. I'm beginning to lose my patience with how much she potties and her pooping in my room. Any help or direction would be greatly appreciated.
