Hey everyone we are looking for some help with our dog. He is about 4yrs and a beagle mix. We rescued him over a year ago from the shelter and he was so great but as time has passed we have to keep him away when people come over because he will nip at them and now he is starting to nip at my 2 yr. She can get a little rough with him and we try to teach her not to but sometimes he reacts before anything has happened. He is great with my other kids and even sleeps right with them. If anyone has a great dog trainer or advice it's very much appreciated!!!
