It was about 33 degrees in my area yesterday and although we have air conditioning throughout the house the dogs were out sunbathing on the deck. Generally they aren't bothered by the heat as long as they're not overexerting themselves.
We only do night walks or late night chuck-it runs in the summer and take the dogs for water retrieves in the afternoon. The spaniels are kept in full coat year long and as long as we pick appropriate activities for appropriate times of days they don't have any issue with the heat and it can get awful hot where we live.
Same, can get very hot here in Sydney in summer also, and walk early in the day or on dusk, if in middle of the day it's in shaded areas or near water. Have always given ice for a treat ( started when Flo was a teething puppy) cold carrots, and always access to loads if drinking water. We don't shave our cocker in summer, in fact some people are of the opinion that the full coat is self regulating in keeping the heat out
but do have the tummy shaved in summer to help cool the dog. They are very good at working out how to be comfortable.
I grew up in Queensland ( Brisbane) , which is much hotter than Sydney, and my childhood cockers were just fine in working out how to cool off without air-conditioning, and in those days no one shaved their dogs, but my childhood cockers always got overly excited when going to the beach! And now I think it was because if the delight in getting cooler.
