It appears my little import dog is pretty heat intolerant, at 16 degrees celcius(61 farenheit) after about 20 minutes of light running(in a large field/yard playing with some friends) and some heavy wrestling he was panting quite a bit-enough I wanted to keep a bit of an eye on him.
It regularly hits 25 (77 F) here in the summer, so he's got a lot more to deal with coming up!
Anyway, I have a cool dog bandana, similar to this :

Was also thinking of getting this :

the concept seems effective... anyone have any experience with it or have other suggestions?
