Please help! We have a six year old Cockapoo girl who is the most gentle dog ever, she’s very well socialised and plays well with other dogs. She stays with a dog sitter when we go away and there are always other dogs there too - no problem. My girl is submissive and always greets other dogs with a submissive stance. My son has a nine month old Cockerdor girl and because they live in a different part of the country & Covid we have not had a chance to meet before. This week they are staying with us and it has been a nightmare from the beginning My son’s dog is larger than mine and is able to just take toys out her mouth, my dog can’t do anything about it and just has to let it happen. I don’t suppose it’s making her very happy. I have tried to stop it but it happens too quickly. My son’s dog is trying to be friends with my dog, apart from toy snatching, by using the play stance and the submissive low stance but my girl is having none of it. She is snarling and trying to attack every time the younger dog comes near her, especially when we are in the house. I think I should remove my dog as soon as she is showing aggression and bring her back to the room when she is calm but my husband thinks I shouldn’t & that I am forcing her to demur to a stranger on her territory. I just don’t know what to do - please help!
