We have a black cocker spaniel who tends to get too warm in the summer. We're about to do a load of work on the house but at the moment, it's fully carpeted (horrible old ones that will go in the work!). In old house, we had tiles downstairs so he used to cool down just lying on the tiles and now he can't do that.
I can see a lot of cooling mats online but not sure if there are some better than others. He often scratches before he lies down if that's a factor. Quite happy to do without one but if there is one that works also willing to try it.
We've also got a week away in a caravan in August and if it's hot, I'm thinking it might be of use then too
