Arf PetsPet Dog Self Cooling Mat Pad for Kennels, Crates and Beds 23x35

My 110 lb. dog likes to roll around on his cool mat. he has ruined 2 by forcing the gel into the corners of the mat. will the arf pets mat hold up?

How does it hold up over years. Any decay in the inner material?

Will this keep my dog cool outside?

do i need put this mat in the refrigerator before give my pet to use?
