I found a unique little product named Speed-E Drink. It's a handy way for me to carry water for my dog and myself. You can get this at most pet supply stores for less than $5! When I am walking my dog, it is just as important to keep him hydrated as it is for me. That it is why I purchased this handy dog waterer. Made of durable plastic, it is basically a mini dog bowl that holds a ½ liter water bottle and clips to my belt. Not only does it make it easy for me to carry a water bottle for myself, but also it makes it so simple to give my dog a drink whenever he needs it.
I not only take this on walks, but it comes in handy on long trips in the car too. It eliminates the need to stop somewhere to give my dog a drink.
