you need on that supports the trunk and one that has a handle behind the neck to grab in case of emergency. this does both. and never to tight as they need to breath and expand there chest.

Pros: works nicely

Cons: none

We have 2 of these a small one for Abbey and the larger one for Happy and we always put them on when we are out on our boat. And they can be seen in the bright color. GREAT PRODUCT

Pros: keeps our girls safe on our boat.

Cons: None

Great for the dog who is scared of water. Saw this used on Tv for dog who was scared of the water because the owner had overfed him and he was really on the heavy side. Worked well.

Pros: Easy to put on.

Cons: none

Every Dog must have one if they're out on the boat. You never know when an accident might happen! The bouyancy is good, easy to put on the dog. Cleans easily if it gets diry.

Pros: Easy on. Great bouyancy

Cons: none

We have a few friends with boats...and Katie is always invited for a day out. Although she has never fallen off...I feel better when she wears her life jacket.

Pros: Safety first

Cons: could be uncomfortable
