Prepare for unexpected vet bills
This sort of activity is perfect for a dog that's as brainy and mindful as a Labloodhound. Best of all, it's really cheap and very easy to set up! All you need to do to help your dog get into this game is get a hold of a couple of plastic rings and some sort of rack for them to stack the rings on.
Labrador Retrievers are pretty good swimmers, which helps their Labloodhound offspring out a lot when it comes to Dock Diving. This activity is relatively simple; all you need to do is gain access to a pool or other fairly shallow body of water, toss a ball in it, and prompt your dog to swim after it and bring it back.
