Your Dog May Not Need a Coat
Most dogs are born with a coat, and a pretty sophisticated one at that. The skin and fur perform extraordinary functions – regulating body temperature, wicking moisture, and repelling ultraviolet light and toxins in the air.
The default state of being for most dogs in moderate climates should be to not wear a coat, and raincoats are almost always a bad idea. Winter coats, however, are a different story, and it serves us well to pay attention to breed, age, personality, and health conditions.
Some breeds have evolved to withstand and even thrive in extreme weather conditions and they have fur coats that should not be messed with: huskies, malamutes, and many shepherds, to name just a few.
Dogs that are small, old, sick, or have short hair are more likely to need a coat when it is very cold outside. That being said, don’t rush into it. Pay attention to the signs, and have a coat with you but not necessarily on your dog.
One thing you may also need is a thick skin to ignore the scoffs and disapproving looks from your fellow city denizens who (incorrectly) think that everyone should have a coat!
