Excellent Used condition canine flotation vest. I used this for both of my Shepard dogs, they did excellent with it. a little adjustment in the straps and it fit them both perfectly, and they both learned to swim without trauma.
one strap for the chest, and one under belly, and a grab strap if they need help going in the right direction or to pull them into the boat or up on the dock.
taught them to swim without confinement, yet they had the security of knowing they were not going to sink!
(no.......dogs do not naturally know how to swim)
Our Belgian Shepard (115 lbs) and German Shepard (78 lbs), loved this vest and would swim for hours with us in our gravel pit.
It's been around for a very long time and still looks great even after all the use it's had.
