The Critter’s Inflatable life jacket is the first and only automatic inflatable life jacket for animals. It uses the same technology and UL approved materials you would find on an automatic inflatable life jacket for humans.


  • Low profile when uninflated
    • Allows for increased comfort and range of movement
  • Superior buoyancy and stability when inflated
    • Under neck support to elevate head out of water
    • Side support for increased stability
  • Fully adjustable harness
  • Handle and industrial D-ring for lifting and leash


How does it work?

Different companies use different methods for auto-inflation. The Critter’s Inflatable life jacket uses a Halkey-Roberts inflator which has a water soluble bobbin whose core dissolves within 5 seconds of the life jacket being submerged in water. Once the bobbin dissolves, a spring loaded needle punctures the CO2  cylinder which then inflates the life jacket.
The bobbin and CO2 cylinder are single use items. After each automatic inflation, these components need to be replaced and can be purchased in a rearm kit.

If your pet is entering the water as part of a pre-planned activity, place the life jacket in manual mode by removing both the bobbin and CO2 cylinder, then inflate by blowing into the oral inflation tube.

To deflate the life jacket, insert the cap of the oral inflation tube, inverted, into the tip of the oral inflation tube while squeezing the bladder to remove all air.
