Just wanting some advice for my 18 week old Maltese x shih tzu. Lately he has really had a biting problem, but he mostly bites me and not my partner. It only happens when my partner is home and at first I thought it was an attention thing but he has been getting enough attention. We also spend each afternoon outside playing with him and take him for little walks. I've tried saying no, that didn't work, I've tried ignoring him but he continues to bite and his teeth are sharp! Can someone please give me some other suggestions! Will he grow out of it? Should I try the water spray bottle?
