Dezi is almost 4 months old. My sister has two yorkies they are both 5 years old (female and male). My sister does not have any kids, so these two yorkies are really spoiled and they are truly adorable! Dezi goes to doggie day camp and attend pupply classes on Sundays. She is very social with kids, adults and dogs of all sizes. My sister and I have tried to get her dogs together with Dezi for the last month. It is just not working. Her dogs will not accept Dezi. They actually snap at her without growling so we have to be extra careful. My sister will hold all of them together and her dogs will try to get Dezi. I was going to leave my baby with my sister, but I am afraid that they will both hurt her. They don't like her and as much as she tries to play with them, they refuse to interact with her. We went to the doggie park yesterday and her dogs sat on her lap or on the bench and did not move. If a dog came near them, they would growl. I had Dezi on her leash (I don't trust her off on her own since she is still a baby) and took her around and she interacted with other dogs (she was a little shy). She is not shy around the dogs at doggie day camp and puppy school, but when she is around my sisters dogs, she looks scared of them. Do you think my sister's dogs will ever accept Dezi? Is it because they are 5 years old and Dezi is about to be 4 months? I've decided not to leave Dezi with my sister (she works during the day) because I am afraid they will both hurt Dezi. Do you agree with me??? Please advise.
