Make sure to measure your dog so you get the right fit. This is for a large dog 32~37 inch)but barely fit my Lab mix. There is a handle on the back so you can keep control of your dog in and out of the water. It is super cute to turn a big dog into a little fish. The nemo bright orage and white make the dog easy to spot. #Rankboosterreview #Sponsored #LOVESPOT https://www.amazon.com/Lovespot-Floatation-Adjustable-Swimming-Available/dp/B071HQJ6CK
