How can I tell if my dog is cold and maybe needs a dog outdoor jacket?

Closely watch your dog on a cold day with wind, rain or snow. Hereby, the way your dog moves is important: If your dog is tense, pulls up their back like a cat or tugs their tail under their belly, they are probably cold. A visible muscular shiver is highly typical and also an important clue. At the very least, when your dog does not want to go out anymore at all, you can be certain that your dog would like a warming jacket.
