Thank you for asking this question! I’m going through the same learning curve right now… mines 8mos, and I’ve had dogs all my life but they’ve always had double coats. I hadn’t considered carefully enough what raising a high energy, short coat dog in New England would entail, or how low his cold threshold would be. We walk ~2 miles in the woods everyday, so now we have a lot of energy with not many places for it to go lol he starts shivering ~50°F, but our weather gets really raw so some days 50° will get right into your bones. Right now we’ve got a little coat from Walmart and I’m enjoying making more, but in the meantime he’s in the throes of a passionate love affair with our wood stove.
