Should a dog’s hair be clipped during the hot summer months?
People often cut the hair of their dogs during summer when it is very hot. This is wrong and undesirable. Actually Mother Nature provided hair to protect the dogs from intense heat, cold, biting insects like mosquitoes and flies. In preparation for the heat of summer, there is automatic shedding of the undercoat which conserves body heat. The outer coat left prevents the animal from the sun’s hot rays. Thus by clipping the dog’s hair in summer, instead of helping him, you will make him more uncomfortable.
Clipping the hair on account of a troublesome skin disease relating to some ectoparasites is quite a different matter.
