I'm merely curious to what people have to say about this. Does anyones dog pant at night, when it's cold? It's cold here because it's Winter. Some nights I've woken up to Sunny panting heavily, wide awake, head up, laying there. I normally have water down but I've forgotten lately, he wouldn't always drink on some of the nights I woke up. I did let him outside just before, I'm guessing he had a drink, not sure, he strolled back in when he was ready. He does sleep under the blanket, not sure if that matters. Any idea why a dog may pant through the middle of the night, while it's cold out? It's cold in my room. I'm out in the shed.. So, it's not hot at all being Winter.
