We used a heated dog water dish for years. Gives the dog water whenever she needs it. No more frozen bowls or scraped knuckles from trying to fill the water bowl. It doesn't make the water warm...just keeps it from freezing.

Pros: No more iced over bowls

Cons: none

While I think this idea is incredibly inventive, I don't think I would recommend having one... no dog should have to be outside in that kind of weather! That being said, you could use it for other outdoor animals though. Interesting concept!

Pros: Inventive

Cons: Dogs shouldn't be left outside in freezing temps

Allied Heated Pet Bowl is good for using in the winter because it keeps the water dish from freezing. Our cats drink out of it all the time and it works really well. The only bad thing about it is that it is hard to clean because it is so large. Otherwise, I think it is a great thing for outdoor pets.

Pros: keeps water cold but not frozen

Cons: awkward to clean because it's so big

This water dish allows your pets to drink nice water even when it's below freezing. It warms the water up so that it's just the right temperature. It is a great bowl for your outdoor pets.

Pros: keeps water at a nice temperature for your pets

Cons: none

I love this bowl. I have my cats inside but in a non heated area in the winter time. When it gets way below O this is really great. They don't have frozen water. It is good for 20 below temperatures. The only problem is they are only guaranteed for 1 year.

Pros: Great for out doors

Cons: None
