How It Works

All you need is a garden or shower hose, any type of dog shampoo – and a dirty pup!

Step 1: Prepare & Set
Attach the Pup Jet to your garden or shower hose and fill the bottle with any dog shampoo. Select your preferred spray mode on the nozzle head and adjust the soap flow using the dial.

Step 2: Bathe, Rinse & Reward
Activate the water flow with the handle to create an effective soap mix that cleans your dog quickly. After bathing, switch off the soap, rinse your dog thoroughly, then dry and treat them with love and treats!
