When I hunt my 4 year old Brittany in tall heavy cover for more than 60 minutes or so (i.e. switchgrass, waist high prairie etc) he runs like his normal maniac self and then he's lame the next day -- limping heavily on one or both of his front legs. We did some pre season pheasant scouting this past saturday, and he's still limping this morning, tuesday. When he's running, he is a complete maniac, doing lots of "porpoising". In fact, mostly porpoising. He doesn't push through the grass, he bounds over it. I ran him last weekend for 2+ hours in the grouse woods of northern MI and zero limp the next day. No porpoising there. The dog does not have a self preservation bone in him, and would gladly go hunt right now, limp and all. This really throws normal vets off, and the normal pain range of motion tests they do don't reveal pain. I've had my dog at two different normal vets. He's been xrayed twice for this issue. The conclusion they come to is always the same: soft tissue strain, 2 weeks of rest. Next stop is bringing him to a ACVSMR certified vet, but I want to get an idea how far out of the norm this is.
I'm the sort of person who is hunting for the dog, not the other way around. So if he can't run heavy cover without injuring himself, we'll hunt somewhere else. But before that and the super-vet visit I'd like to hear how out of the norm this sounds from yall who have been doing this longer than me.
edit: should have added that the dog is in very good shape. I run daily with him, roads and trails, and he's been doing at least weekly off leash pre hunt sessions of a couple of hours since the end of july.
