Hunting and Working dogs get a lot of bumps and bruises, our job is to watch them and take care of them, but that doesn't always mean a vet visit.
Sure, bumps, bruises, cuts, etc., happen. And if you know exactly what the problem is, you can make a judicious decision about whether to go to the vet or not. But until they reach full growth, bone development is a serious issue in pups.
Anything that might indicate a structural injury in a pup should be checked out
immediately. The pup might have a high pain threshold, but walking, playing, and hunting for a week with a dislocated shoulder could affect bone and joint development and have long term effects. I'd hate to see a good dog's working life shortened for lack of vet care when it was a pup.
