I am trying to find a heated pad, the one I am after is rigid,covered in fibre glass or some thing similar, an old friend had one, it was marvelous, thought I'd found one but I've lost it again***oops!, it must be big enough for retriever
any suggestions appreciated,Thanks

www.petnap.co.uk
they have just brought out a larger size heat pad.

I can recommend this company too as they also trade as petnapltd on Ebay and when I approached them previously for advice they were really very helpful.  I haven't bought any of their products as I am not intending to breed yet.  They actually do a fantastic heated bed so that all the base where kittens or puppies will be laying are covered, not sure if it goes up to retriever sized but well worth asking them.

thanks for your help, I have seen this site, the pad I was thinking of was a "snugglers" and I think they are no longer trading
