Heat pad brand/recommendations or other ideas?

[Hairyfriend]

We are renovating and delays mean we are living in a caravan in the garden. Not ideal I know when collecting a 10 week old pup! The van floor gets freezing, and stays cold- even with gas heating on! Are there any recommended electric heat pads/brands or other solutions to consider?

This one is good, use it for our Guineapigs heated about 8pm still warm in the morning

Thanks so much for the suggestion.
