I've only had Lola now for 4 weeks and have noticed that she does not like other dogs, regardless of breed and/or size. I tried to have some socialization with a friends dog who is extremely submissive. Lola nipped 2x and then tried to pick him up with her mouth. (the other dog is a bichon frisce). We spent about 30 minutes and finally got Lola to atleast leave him alone after she spent a lot of time sniffing him. Any suggestions on how to socialize her and stop this aggression?
