I have 5 YTs with major jealousy issues. If two are on my lap they end up fighting viciously. My dogs are in no way aggressive (other than when being petted or held by me). This happens only with me, not my husband or any other family member. If I have one of my YTs on my lap and another comes within a foot of me, prepare for war! My dog are great besides this issue and it's really gotten out of hand. Starting to really bother me. Anyone have similar issues or advice?
