For as long as I have been around this breed (50 years), mixing one with ANY other dog was considered risky at best. And maybe that is one of the reasons these dogs have an appeal for me - able to be the only dog in the 'pack' (of humans). And seeing how I am more micro-social myself isolating a dog from other dogs didn't seem out of line.
Well things seem to have changed. With the breed being 'challenged' (BSL), isolation could be equated with aggression? Plus most of this breed's (responsible) owners live in more populated areas so if they are going to be able to take their dog off their own home base, the dog had better be stellar around other dogs. Yet the newly popular dog parks wouldn't be my choice for getting Strak acquainted with dog manners. Its not so much the dogs that I fear, its the air headed owners who think "friendly' means can turn loose without worry. Of course you know who would get blamed for any fighting! So that is out as an option all together.
Some folks do doggie day care which sounds good, but living 1+ hour from the nearest place that has such a facility puts a damper on that idea. Any other ideas I might consider?
