I'm trying to figure out what has happened to my poor Tobey.  Last weekend I noticed he was not feeling very good; he was lethargic, didn't want to play, and the biggest clue of all...he wasn't hungry.  I left for a business trip last Sunday so I called every day to see how he was doing and his grandpa said he was back to his old self by Monday night. 

When I got back Friday I was petting him and massaging his back and I noticed what felt like little scabs all along his back.  From his neck down to his tail/stump he had all these small little hard spots and when I looked at them they weren't bloody like a scab but more clear little clumps.  They are very small, but it is easy to feel them when you run your fingers down his back.

I probably wouldn't have thought anything more about it, but I'm realizing he had an episode exactly like this about a year ago.  In thinking about the previous episode, it presented the same way - lethargy, no appetite and then dried little scabs/blisters along his spine.

It seems like a reaction to something but I have absolutely no idea what it could be.  I haven't changed his food or medications and he hasn't been anywhere new, which makes me think it might be something in my home.

Has anyone else ever seen or heard anything like this?
