Is it possible a foxtail or tiny sticktit type seed has wedged its way under the skin? Here in WA we have these tiny little black seeds that stick to the dogs fur, and if they work their way into the skin a little infection can form around it. If your dog is black it would be very easy to miss.
Yes, my dog is black and white.
Do these seeds normally appear in regular lawn grass? If the infection is squeezed open, do you see the seeds? I do not notice any black spots in the puss that comes out.
I was just wondering because we live in a small town and Pinto does not get into the bush often. She not only gets these "zits" in the summertime, but in all seasons.
Thank you for your response back.
Dogmom, you took the words right out of my mouth. The first thing I thought of as I read the OP's post was "I'll bet it's from foxtails."
Foxtails can cause some really nasty abcesses and I've seen dogs almostly completely debilitated because of them. They're quite nasty and if they grow in your area, you need to either scope out the places where your dog runs and try to get rid of as many of them as you can (sometimes an impossible task depending upon the lay of the land), or find somewhere new to let your dog run.
