[help] My dog keeps bringing poop into the house

Hi, I have a 4 year old small mutt and she won't stop bringing poop in the house. When we let our three dogs outside she will almost always come in with poop from either her or form our black lab. We have only had the dog since March and she just started doing this when it got warm out. I don't know if this is a behavioral problem or a medical one. I also don't know if this will cause her any health problems. Any help or advice would be greatly appreciated. via /r/dogs http://ift.tt/2rygLaq
