Hi all, I recently adopted a 2/3 year old female dog from Greece. She arrived Sunday, so has been with us for 5 days. She regularly stays with my grandparents, who have a 10 year old female black Labrador. Both dogs are "submissive" with people - and our old black lab does have general anxiety. They are both neutered. However, my new rescue, who is the sweetest dog ever with everyone else including other dogs, keeps going for our old black Labrador. I'm thinking it's jealousy and possessiveness between them, and they're both fighting for my attention, but I hate seeing them fight like this together. Any advice would be amazing! Thank you so much.
