I am a proud owner of 2 beautiful german shepherds, Kandi 3 and Titan 9months. Kandi is very jealous of titan or any of the other animals that come near me or get my attention! She nips and has even attacked our miniture dashound! She is great with people and children but I can't get her to stop her jealous behavior! Titan is still a puppy but is as big as me on his hind legs. He loves attention and is always by my side, except when I fall asleep! He chews on everything! I don't know what to do about it! I can't punish him 4 it cause I don't know he has done it till morning! How can I stop this behavior while I am sleeping? He is too big 4 a crate and never does it when I am awake!
