Somebody buys a Husky in December. It is beautiful until May. By June it is lying on the bathroom floor, panting, losing weight, and the family is quietly looking for someone to take it.
Heat is the thing to get right here, and two features decide most of it: a short muzzle and a thick double coat. Panting is a dog's only air conditioner, and a flat face is a bad radiator.
Which dogs have you taken through a full summer, and in which city? Karachi humidity and Multan dry heat are not the same problem, so please say. The ones that surprised you by coping are worth hearing about too.
