Ive read up on introducing chins... I have a pair mother and daughter whome I'm trying to introduce to a third girl ( unrelated).... Quarantine is over and I took all three of them to the vet for check ups already... I've let them interact with each other through the bars and even switched around some of their toys to mix up the scents... What kind of behavior am i looking for if they seem to like each other? I haven't let them physically interact yet. Since I'm introducing one chin to a pair do I need to do it one at a time or both? I guess I just am an overprotective mom and don't want any of them to get hurt
