Just like you and me, sweaters and outerwear are so important for us, so I don’t see why it would be any different for your pet when they’re outdoors this winter…. Yesterday, I saw this article online and I think it would appeal to you and answer your questions. It’s online at PetProducts
I think a sweater is a good idea - if you start them young, they don't freak out about the feel of it on them. My sister has a Rhodesian Ridgeback (sp?) and he's much happier (and warmer) with his sweater on.
My hubby thinks it's silly and mean to dress dogs in any clothing - but he's the first to cover them with a towel or light blanket at night if it's chilly in the house!
My Mini Schnauzer has coats, sweaters, long-johns, boots, etc. I was one that NEVER put clothes on a dog....until the Schnauz came a long. He just can't stay warm long enough to enjoy a walk or a hike with me and the Newf this time of year, so, bundled up he gets.
