The first thing we'd like to mention about the Critter's Automatic Inflatable Pet Vest is that it is not for swimming since it will inflate if submerged. You can switch the firing mechanism to inflate manually if desired, but we didn't see the point. Our take on this is if you're planning to take your dog swimming, you'll have to purchase an inherently buoyant life jacket model. If your primary concern is an accidental fall overboard, then this jacket is a good choice because it is compact, yet effective once inflated.

This jacket took some time to learn how to don and adjust initially. With all the straps and an inflation canister it appeared as though we were strapping on a rocket booster to our oblivious volunteers. We were also concerned how our pets would respond to the sudden noise of a discharged cylinder, so we opted to try it on dry land first. As you can imagine, our unsuspecting friends were immediately alarmed by the hiss and sudden inflation.

After our tests, we contacted the manufacturer who suggested against testing on dry land first. Regardless, it was done, and we moved to our on-water portion of our testing. To our surprise, the canister made practically no noise since it was discharged underwater. The dogs barely noticed, which is probably why the manufacturer suggested against testing on land. It was actually quite thrilling to see the dogs leap into the water and bob to the surface once inflated.

The Critter's Vest is compact when packed and armed and was easy and comfortable for the dog to wear. Once inflated it easily quadrupled in size and floated the dogs very high. Our testers commented it would be a good choice for the cruising boater and pet owner, but stressed it was not a jacket for water play. The cost of the Critter's Inflatable Pet Vest at the time of our study averaged about $130. However, their website indicates that all jackets are on inventory clearance sale for $60.
