Started Nipping My Yorkie is three and has never nipped or been aggressive until recently. Twice he attempted to nip when one of the grands went to get him from my bed to take him out. And last night, he was chewing on something he should not have been--which is a new thing, too--and my husband reached to get it. I am so surprised because he's been so good, even with the grandkids treating him like a playmate. I want to know what is the proper response when he does act aggressive and what may be causing it.
