CALGARY -- A forecast of hot weather combined with forest fire smoke blanketing Calgary is making it challenging for pets - and their owners - that like to be outdoors. While cats are mainly indoors where they sleep for 70 per cent of their lives, dogs need more attention and outside time. Jessica Bohrson, the senior manager of communications at the Calgary Humane Society, said dogs can't handle too much heat. "What we recommend is to keep their bathroom breaks as short as possible," said Bohrson. "Try and get their exercise periods in when the smoke is a little less, so maybe in the earlier morning or the later evening and honestly just trying to keep them inside as much as possible."
