Kalimdor vs PupFlask vs Bonza: which dog water bottle for your walk

Your dog won't ask for water until he is already behind. Three ways to carry it, and each wins a different walk.

Head to head, need by need

Big dog, long hike: PupFlask wins

A stainless steel bottle in 27 or 40 oz, with the bowl built in, so there is nothing extra to pack. The seal is leak-proof, so your pack stays dry. The 40 oz covers big dogs on long hikes. The 27 oz is plenty for a smaller dog or a shorter walk.

Daily walks and moderate hikes: Kalimdor wins

A 19 oz leak-proof bottle you run with one hand: squeeze to dispense, release to stop. It is compact and sized for walks. Big dog on a long hike? Bring a second bottle.

A bowl that folds away: Bonza wins

A 33 oz silicone bowl that collapses flat, with a carabiner that hangs it from the leash or backpack. It holds more than the Kalimdor bottle and fits in a pocket. The catch: the soft sides tip with big gulpers, so set it on flat ground.

Long hike, big dog: PupFlask. Daily walks: Kalimdor. Fold-flat backup bowl: Bonza.

The catch on each

• PupFlask: heavier when full. Carry it in your pack, not your hand.
• Kalimdor: sized for daily walks and moderate hikes, so a big dog on a long trail needs a second bottle.
• Bonza: soft sides tip. Rinse it before the trip home.

Which one to buy

• Big dog, long trail: PupFlask in the 40 oz.
• Small or medium dog, daily walks: Kalimdor.
• Car trips and a spare for the pack: Bonza.
• Heavy gulper: pour into a bowl on flat ground.
