Sheila I am so glad this does not seem to be health related as that can be so difficult. just a thought here.... Met does not handle heat well due to one of his medications. When we had to be out in heat, I gave him some good ice packs. It cooled him down and totally changed his endurance and ability to work when it got too warm for him. I am not talking 100 degrees. 75 is about his tops generally without icepacks unless there is a breeze along with it. If this might help, it is certainly an easy fix. If I recall Shelley had done this for Judson as well. These coats are dogs have to wear all summer seem so unfair- maybe that is why Met loses more than he should LOL Karyn and Met
