Our new rescue dog is about 4 and is fully house and crate trained- but he seems to go potty much less frequently than I am used to. Most of my other dogs went potty 3-4x, and had at least 1 BM per day. We have had him a week and he seems to only go 2x, and sometimes no BM. Is this normal? Is this part of his adjusting you think? Sometimes we will take him out and wait long periods without him going at all- which gets frustrating. I hate to just bring him back in, but i he doesn't go after a certain amount of time should I just give up?
