3 of my 4 pooches are squish-noses and cannot take heat,
one of my pugs overheated once on a 3-block walk(!) in my desert like town and my vet who is next door showed me how to cool them down safely,
he sprayed rubbing alcohol on her feet, which since it evaporates quickly leached heat from her,
and then he poured cool water on her back (NOT ice water as he said people have an inkling to do),
so with my squish-noses, on long outings i now carry clear alcohol with me, it also serves other purposes
( and no, knuckleheads, i don't mean a good IPA beer

)
