My dog is similar. The number of cooling mats I've bought her while she lies on a rug, panting because she's too bloody hot

It sounds daft but I rinsed a tea towel in cool (not freezing cold as I believe that can cause them to go into shock) tap water and draped it over her. Not sure if it helped but she was fine with that than actually sitting on the cooling mat. My dog has also just had her groom so hoping her shorter coat helps her next week. PS My dog is a terrier so does fit under a tea towel.
