Timber has very little hair around his inner thighs and is quite sensitive there. So, while I use a pinhead brush or a slicker for other areas, in that area I use a soft bristle and I also hold the skin so I'm not pulling on it too much. A few days ago, he got an insect bite and did a bit of licking which in turn caused a little matting, fortunately not too close to the skin so easily snipped off. But, trying to brush there is annoying him now and he gets a bit grumpy when he is handled on anybody's terms but his own (he'salways been a dog that doesn't like being fussed with). Any tips?
