I really caution folks when considering anything electric that your dog will consider "his". There is a real chewing risk here and I would really have to think twice before using. A better alternative would be to put the water out of the wind and cold, to use a ceramic or plastic bow. I know it's hard in cold climates but accidents do happen.

Pros: Sounds good on paper

Cons: Beware with dogs that chew.

These bowls are great, they keep water from freezing and the way they are made dogs cant pick them up and dump them, The only think is plugging them in if you dont have outside outlet, cord can kinda get in way.

Pros: keeps water from freezing in freezing temps

Cons: cord can get in way

I bought one of these electric watering bowls last winter for my outdoor cat. It is a great product and I would recommend it to anyone with outdoor pets that live in the cold. Even in the coldest temperatures (40 below) it kept the water from freezing. I give this bowl two thumbs up!

Pros: Works great keeping the water from freezing, reasonably priced

Cons: Could have a little longer cord.

My family used to use this bowl for our outdoor dogs. I really don't have a use for it anymore, but I still have it. We had gone through several other heated bowls that eventually stopped working after a winter or two. This bowl has lasted for years and is a keeper!

Pros: durable, keeps unfrozen water available outdoors in winter

Cons: none

We feed the stray cats in our neighborhood, so this is great in the wintertime. In a regular bowl the cats water would become frozen so we would have to change it every couple of hours, but with this we just leave it and only have to worry about their water once a day.

Pros: It works great

Cons: I cant think of anything
