We have a 90 pound Golden and we got him the biggest one from West Marine. It works great, we were not sure if we would be able to find one since our Golden is bigger than most. West Marine let us bring him in the store to try them on him before we bought it.

I have a 110 pound Yellow lab and this will hold him up to float. I can also stand on the swimming deck and pick him up to get him out of the water X large size

Yes, very easily. And she seems very comfortable in it.

I've got a 74lb Golden and I bought her a jacket from ruffgear been the best dog jacket I've seen

Best dog gear ever

i bought my lab a paws aboard life jacket and i agree with "jwurl" they do not provide enough flotation for the dogs.

i have a like new condition dog vest w the handle on top...it goes around the neck and has a buckle that fastens under the belly to the flotation part on the top. We didnt use it much just when he wanted to swim. it held a 100lb american bulldog fine, but he past away and i wont be needing it anymore.

if anyone needs one let me know

Ezydog I have a 80 lb goldendoodle "owen" I found it online for $50 (xl) last summer I forget where just goggle it shold come up

The outward hound jacket works well for my little guy and they are practically giving it away:

Some of the most important safety preserver items on any boat are the life jackets — for you, your passengers, and of course your "best friend." Since our last report on this topic 12 years ago, the canine life jacket market has taken off by leaps and hounds. Back in 2000, we came up with four viable canine life jacket models. This time, we were easily able to double the number of jackets tested. West Marine has many in regular stock, and so do some of the big-box stores.
