I am going to have to look into this myself. We got to our camp almost every weekend and it is along the river. The river is very shallow, we can walk the whole way across and the water doesn't go above our knees but further down it gets a little deeper. The dogs are always supervised but Abbie is so small and kind of afraid of the water, that if she fell in, I am not totally sure she could get herself back to the shore. She wants to get in the water so badly when Brady is in so maybe a life vest will help ease her fears.
I want to get one for both dogs just because you can never be too safe.
We are also going to be taking the dogs out on the boat and there is no way I would let them go without one.
*hmmm...off to look for nice doggie lifejackets*
