I could be wrong, but greys have to where a muzzle in a public place.? If they are loose and they went for another dog, more so a small dog . You would have alot of shit, from owners and if it got back
to the greyhound kennels, because they are trying to promote them as good pets, and its the last
thing they want . If i was you keep him on the lead+muzzel, its what they are used to. I helped
a bloke with greys [45], and if a 65lb greyhound kicked off, it can do a lot of feckin damage
its not worth it
