My little girl is 9 weeks old. The first week was great. No accidents and it seemed that she was learning so fast. (We are bell training). Here we are almost 2 weeks in and it seems we’re going backward. Accidents right after she comes back inside. I am with her 24/7 and I go with her outside, so I see that she is relieving herself and gets plenty of exercise for her age. Is this normal? I don’t think it took this long with my other 2 dogs. Any advice?
