There is some good advice here, but I'm still dealing with a jealous son after one year. Maggie has been here for a year and Buster is still so very jealous. They get walked together and separately. If I take one somewhere (in the car or to walk) and don't take the other one, the one that gets left whimpers and cries.
They have always gone to the groomer together. It is difficult at times but Maggie is here to stay and so is Buster. Maggie is bigger than Buster and she is the dominant pup. I think a lot of her biting and jumping on Buster is to get him to play and he wants no part of it. She will growl and nip at him when he is whining. They really get into a growling match when someone comes to the door, they both want to be the first to greet whoever is there. I am still waiting on them to get along, one year and counting.
