Hi! I have a 2 year old Boston Terrier who isnt that great around a lot of other dogs. I would really like to do agility with him but I dont think that would be possible with how he is towards other dogs. I have been looking into Schutzhund/dog sport though because it looks like a fun and interesting sport. I know that it is typically a german shepherd/rottie/belgian breeds etc sport but have seen videos of a jack russel doing it. Does anyone know any information about this or anything?
