I'm at wit's end.
The results came back from the lab at the University of Georgia, and they confirmed no cancer or fungus. That's the good news. The bad news is they didn't find anything (I call that bad news because we still have no idea what this is so we can't even start to treat it!)
The vet, as a last shot in the dark, put him on Clavomax for a week. He got his last dose last night. It did not improve him in any way, and he's gotten increasingly lethargic.
If I take him to the park, he runs & plays almost completely normally. However, at home, all he wants to do is sleep. I've been practicing some agility stuff with Lola, and he's very interested & is picking up everything I've been working on with her. He eats normally, but I've had to increase his food slightly because he seems to be losing weight.
I spoke with the vet on the phone last night, and she says she is at a loss. She has nothing else she can do except refer him. She told me to take him off the Clavomax for 2 days, see if he perks up & then call him back.
She mentioned referring us to an internal medicine specialist & doing bone biopsies & using more sophisticated equipment to search for a fungus that could be hiding somewhere that she can't see.
I'm so frustrated. We have exhausted our vet funds on the procedures done so far, and don't know where to go now. Any prayers, thoughts, good vibes, anything at all would be much appreciated. I'm getting a bit depressed watching my dog suffer. He shivers all the time & just wants to sleep on our laps with a blanket over him all day (not much of a difference from before really, other than now he doesn't have bouts of playtime in between naps. Just constant naps.)
