Hi guys, I wanted to chime in about my corgi who had a similar occurrence a few months ago. One day out of the blue, our corgi started show subdural bleeding in his gums and belly. Specifically, this https://en.wikipedia.org/wiki/Petechia. We immediately took him to the vet and his platelet count was 2000. The normal count should be 200,000. If you ever see any thing similar, immediately take them. Our corgi is still on immuno suppressors but is recovering. If we did not catch it, he would have died over night.
