My dog will not drink water when he is home alone. Recently this has been causing issues, I believe, with heat/dehydration. He has twice collapsed after I get home from work. I have have started giving him a bowl of gatorade before leaving for work so that he has SOME fluids in his system. The house is air conditioned and so not hot during the day. I am at a loss of what to do to help my dog. My work is too far away to come home during the day to get him to drink or eat ice cubes. In the winter he eats snow, as he has access to outside through a dog door. This summer is becoming a real issue. Any advice from anyone would be greatly appreciated. By the way he is a 9 year old Sheppard/Spaniel mix approx 60 lbs. Thanks!
