RE: water in the field
 

There are all kinds. It just depends on how much stuff you want to carry.

1. Cool Pooch Water Bottle

2. Thirsty Dog

3. Handy Drink

4. Or how about a Gatorade or Propel water bottle with the twist top?:


Personally, I use number 4. Squirt some in his mouth, away we go. Keep a jug to refill your bottle in the truck.

Enjoy.
