Foxy's paw

We were at the allotment the other day and noticed Foxy limping a bit that evening. One of his pads on the right front paw was very red and I think he must have caught it on a bit of glass or something. The whole top of the pad is missing.
I won't subject you to a blip of the injury itself, don't want to scare the children, but this is him with a dressing I made for him.
In this photo he is hamming it up a bit, he's fine apart from a slight limp which is barely noticeable since putting on the dressing.

At least he has a real excuse for not going for a walk!
