Hi MrsHogofthehedge
Nice to see you have hogs around. It looks to me as if you might be right and the hog is having a good sniff and it is his lungs expanding. It looks exaggerated because of all those spines! Also he looks fairly small, but sometimes video is deceptive. However, hogs do sometimes get breathing problems – possibly from worms, so if he is making a lot of noise when breathing, (I don’t mean the noise they make during courtship) and you are concerned, it might be worth taking the advice of your local carer. If you don’t already have contact details you can get details of your nearest carer from the BHPS.01584 89080.
It isn’t certain that there is more than one hog, even if there are two nests. They sometimes change nests during hibernation. I had a little chap here all winter. He spent ages building a nest in one of the boxes but mostly only used it for naps between snacks and must have had another nest somewhere else.
Hope the hog or hogs are ok and stay well.
