I have a good story....not the outcome but WHY YOU SHOULD BE CAREFULL!!! A friend of mine had a German Shorthair Pointer we all know how short a coat they have,She was moving to a home in the country left the dog there with water 2 buckets it was a hot summer day it took us 1 hour to get the second load get back go out back Daimen was laying there lifeless took him to the vet he died of a heat stroke i dont think matters what breed they are they all can die from heat stroke !
