I dont know a brand off hand, but I just use the kind you get at Walmart. I usually get a good one and not the cheapest and they have to be UL, etc. I just wrap it in a towel so the dog is not directly on it an only put it in half of the box so if they are too hot, they can get off of it. I do not let her whelp on it, it is for after its all done and they are settled. I do like the ones with 3 heat settings. |
