I'm looking for someone to help me figure out what could have caused this skin reaction on my dog. 4 days ago, it was just a little blood blister type thing on his back. Now, his skin is cracking and falling off. I took him to the vet on day 1 after I saw the blood blister. She mentioned that his whole back seems to be one large scab and that it will eventually fall off (after much time). We've had blood tests done and fungal cultures. Everything came back clean. The vet seems to think that the dead skin will just fall off and then we will need to wait for the skin to grow back. He's on medications now to help prevent infection. The vet said they COULD do surgery to remove the dead skin. However she did note that it will just fall off on its own. Attached is a picture of how he looks today. Keep in mind, only 4 days ago, it was just a small blood blister. Any idea what could have caused this??
