A couple of months ago I was brushing Jack and he air snapped at me, with a yelp. Turns out I'd ran the brush over a scabby cut rather hard and it had hurt him. Now I don't know where it came from or when, but just put it down to undergrowth. Today I've just been fussing him and felt a hard patch of fur around his face, took out the comb as I thought it might've been a lug. Started to gently tease at it, and scabby bits were coming off. I got some wipes and started cleaning as I combed. Got rid of most of the matted scabby fur and gave it a clean. Unsure of whether to shave the area or not just to get to it properly. But I can't work out what is causing the injuries. It can't be undergrowth because he crashes about as much as Lou and Pen and they come out of bracken and brambles with barely a scratch on them. Then I thought, could it be them fighting whilst I'm out, but I can't see that, I'd notice any tension between them when I walked through the door. Plus the other two would have an injury or two as well as Jack would stand up for himself, he's brilliant at helping other dogs but he will not be bullied. So where do these injuries keep coming from?
