Hello, So I am starting to get real annoyed. I am patient with my little girls. I love them truly but I don’t know what to do . They have a love and hate relationship. My dog gets jealous when attention is directed towards her sister. My dads dog is chill but sometimes stays away because my dog gets jealous and aggressive. I stop her from doing that. I literally had to separate them because they fight in the middle of the night. I don’t really want to cage them but I noticed bite marks on ones neck and a bite mark on ones ear and head. This behavior is getting out of hand. I feel they need behavioral school or something . They listen when I tell them to stop but the moment I let them outside to play or just chilling around the house they sleep laying in each other and three hours later they are back at it. Any suggestions?
