Good afternoon! Tuffy was romping in the backyard with the kids for about 20 minutes. It isn't that hot outside--low sixties but I think he just overexerted himself running around because when we brought him in he was panting excessively, didn't want to eat his lunch and then collapsed into a prone position for a little while. I immediately sprayed his belly with water and offered him water and it helped somewhat but he was still panting nonstop. He ate some lunch and then I put him in his crate in a cool area to relax. In the future, is there anything else I should do to cool him downwhen he starts to pant excessively? Also I know in the summer they recommend some cooling collars. Should I look into getting one of those as the temperature gets warmer?
