HELP!!! Jealous 5 month old
My boyfriend and I need some advice. Our male GSD is as sweet as can be, but lately he's been getting very jealous when my boyfriend and I hug. He will jump in between us and even begin to nip at us until we stop hugging. We've tried putting him into a sit/stay position, but he constantly breaks it. We can't show any affection towards each other because he has to be in between us. We can't even sit on the couch together because he has to be in the middle. It's annoying right now, but we're worried that it may become a more serious issue in the future. Any advice is much appreciated!!
