I hope someone can help me - I’m at the end of my tether! After losing my precious baby last year I got a new pup 3 weeks ago and my older dog hates him. She’s growling and lunging at him. I knew she wouldn’t play with him but I thought they would be friends eventually but after 3 weeks the situation isn’t improving - it actually seems to be getting worse. She lunged at him this morning for no apparent reason - he wasn’t near her and was minding his own business. I’ve tried to get her to associate him with getting treats, petting her and then stopping when she starts growling. When he toilets outside he gets a treat and so does she. I’m scared one of them will get hurt.
