Our dog Jethro is a pit bull. So that makes fitting him a bit difficult due to his big neck and chest. The Ruffwear K-9 Float Coat fits him like a glove. It is very easy to put on and take off. The float coat is very well made. The "handle" on the spine area of the jacket is very handy whether we are at the lake or the pool. We couldn't be happier with the float coat. I would highly recommend this life jacket. And I would definitely buy this product again.
