Someone posted a thread on strollers and mentioned a "cooling pad" being used. A pad that your pooch lays on in the stroller that keeps him/her nice and cool. Does any here use a "cooler" in their stroller? It would have to be something that stays cool for a long time.... especially in the heat that some of us are experiencing. I would love to have something like this!
Please share your info!!
Thanks!
