I bought this for my Nan's Dashound, my grandparents really feel the cold and have the heating on full blast and the wood burner on too. Their dog gets too hot and can't stay in the same room as them. This mat is brilliant it can be put in her favourite spot in the living room, the gel inside is naturally cold, to cool down gently without causing a shock to the system. It's a made of a thick wipe clean material, and the gel inside is squidgy and comfortable. My Nan is really pleased with it.
