Yeeks! Break outs!

Uno seems to be breaking out quite often since July. Most were small bumps but I had a rude shock over the weekend when I found 1 that was the size of a 20-cents coin! It had scabbed over pretty nicely by Sunday and of all accidents, the teeth of the grooming comb got under the scab and I almost yank off the entire scab...Thank goodness there was no damage done
