I just adopted a 2 year old boston terrier on monday and he doesn't seem to go potty a lot. He is housebroken and the previous owner says he will sit at the door when he has to go. So when he does that, we'll take him outside and all he does is sniff around and be his "guard dog" self. He is easily distracted by his surroundings.

He has eaten a little bit and has been drinking enough water, but has only gone pee twice but has not pooped at all.

Do bostons not go potty a lot? Is this normal?
