I need.some advice.about a papillon that has just.started to nip and bite at people he is my brothers.dog and the little brother to my 2 paps minehave never shown this type of behavior and would like some advice from other dog lovers papillon owners as well my brother lives in another state

Just establish some clear boundries. What I do is when the dog bites, I say no. That's important, choose a word. One word. Say it, and then apply some form discpline. Some dogs are good yakking at is that is need, others it just make it worse...so you have to experiment. But soon they here the word no, and they know, what they are doing at that exact moment is not wanted.
