Hello!! I posted a picture below..... has anyone ever seen this before? The bump on his face where he had a whisker is now inflamed, hardened. Not sure if it could just be irritation or something I should see the vet about. 20191003_204754_1570194345177.jpg
Having had one with a mast cell, I always check out all bumps and lumps that do not go away after a reasonable amount of time. This could be a bug bite or a sebaceous cyst, but if it doesn't improve or gets worse, call the vet. Mine responds to pics, maybe yours would too?
