hi,
I cut Balu's hair twice a year, once in April and the second in mid July.
Airconditioning in the car is a must when travelling(4 us 2!!!), and avoiding walking outside from 11 to 17, with the dog of course... I once took her for a walk 3 years ago in mid June at noon and I will never-ever do that again!!! Even though i was giving her water all the time... I was really lucky that she didn't have a sun-stroke!
When we are at the beach, we always cool her head with drinking water every 30 minutes or so and we don't over-excite her with ball-playing/fetch something-anything-but-the-next's-person-towel!!! during the warm hours even if she asks for.
I've read somewhere that dogs don't really realise how warm it is while playing... until they drop down... is that true?
George.
