>>1747306Buy or make a sweater or shirt for your pup, layer it with a waterproof layer if it's wet out or extra cold. Look up some of the signs that your dog may be too cold (most are obvious like shivering, tail between legs, etc.) or too hot (panting, sweating through pawpads, etc.), and try to find a reliable source, not just FB memes. Humane society might be able to point you in the right direction.

Being an animal just means they can't bitch at you in English when they're cold. They still get cold and uncomfortable, don't you want your loyal cross-species friend to be happy and comfortable?
