Hello! I have a 10-year old Jack Russell who isn’t as young and spry as he once was. He isn’t very interested in food and has a lot of food allergies which means that he is quite skinny and doesn’t have much body fat. Recently I’ve noticed that he (especially his paws and nose) feels very cold even when he’s indoors on the couch. Our apartment can get quite chilly and so I’ve been thinking that maybe he would enjoy like a thin sweater or something to keep him warm? Is this something worth getting for him or am I overreacting? Does the cold actually bother him?
