I've noticed my girls have never met a bull terrier or a Basenji they didn't instantly hit it off with. Both are shy and take forever to get comfortable with most dogs but there are a few they just hit it off with. Every single Bull terrier and Baenji they have met they have both instantly loved. Playing non stop and just having a great old time. Are there any breeds your dog seems drawn too? Any they hate? Mine are both afraid of most herding dogs, when they get that herding focus going. They both hide in the corner of the dog park!
