Wow, lots to read. I probably need to go back and read it all, again.
This might be a little jumpy, but some comments on the above --
There's really only a few people listed on the TCVM website, Callie, that aren't listed under equine. I don't know if you recall, but last year you and I chatted a bit about it when he had those weird oozy ulcer things on his paws (which I don't think could have been bites, as we first thought) -- and the one tcvm vet that's more recommended around here only has very weird hours and is about an hour away, which is rather difficult due to my job. I can take a day off but no matter which day I do, at least one of the doctors gives me a hard time since somehow it inconveniences them regardless. The other vet had better hours, but was associated with a 'regular' practice and when you and I discussed, there were some things that just didn't sound amazing about it, so I opted not to do it last year. I went as far as to make an appt, have them send me all the paperwork, but I canceled it since he was all better by the time the appt rolled around months later. Their allergy testing was a sort of voodoo as well, not skin or blood related, but rather vials of things that I would hold, and touch Sammy and we would see if that caused a reaction? Something like that. I am too much of a scientist to trust that without actually seeing it.
UPenn probably does have a great vet school, but they are rather far away, about 5 hours. Cornell is about 6. I could try getting him in over christmas when we're in buffalo but that's still about 3 hours or so. Not impossible, but perhaps hard to schedulem if we're only there for certain days and around a holiday..... that's worth a call though. Who or what deptartment would I try calling? Is it something we would go there for, or have our vet send samples? I've tried looking on cornell's website and it's somewhat confusing to me. Sounds like we could just have our vet send serum, actually?
I wasn't able to get any z/d canned today being sunday so I put the pills down the back of his throat and rubbed until he swallowed and it's not treating him well. will rectify that tomorrow for sure, since he's been sort of snorting funny so I'm keeping a very close eye on him for the moment. The z/d kibbles are incredibly hard, I stepped on them with shoes and they didn't crush so I figure that isn't helping him either, so I whacked a bunch with a meat hammer to break them down a bit. They are pretty big kibbles, too. Hopefully that and adding water are helping.
The vet is doing the spec cpl testing for pancreas, so hopefully the results will be in shortly, along with the fecal. And, the biopsy of his toe that is unrelated but still important. I definitely made sure to ask for the special test for that, since I knew those values hadn't been part of any blood panel he's had done before.
Our vet at least, said that the vomiting could be a reaction to something in the food -- but the fact that he vomits so quickly after eating, rather than digesting and THEN vomiting makes me wonder as well. But, as mentioned, the z/d is as much for the general tummy upset as allergies so we'll see....
I, too, am thinking more of something physical. The blood tests should be back soon and if they don't show anything, then we'll be in for more tests and xrays and such. The vet, at least, didn't feel that concerned with it and actually suggested waiting on blood work until we tried the fancy z/d for a few weeks. I wasn't willing to wait a few weeks, that's for sure!
I'm going to look more into elimination diets -- what other protein sources can I use? I never would have guessed chick peas.... or maybe fish? How would I know which carb to try, is potato a good one, or is there something else less likely to be an allergen? Do I need a carb or can I just feed a veggie? I know it's not balanced, but how much protein do you feed in ratio to carb? As concerned about cost as I was before, it can't be more expensive than the z/d. And I would feel better about it long-term, just because I can make treats and such to go with it rather than really hard, really dry kibble and that's it.
The vet was NOT happy when I suggested something like that the other day -- he didn't want to feed something "unbalanced" -- but then again, they do push the rx diets. I just couldn't think of a protein he hadn't had, but obviously I don't think outside the box far enough.
The more you guys talk about allergy testing, the more appealing it sounds since having some sort of answer -- at least to define if it's food or environment, or both --would be faster and cheaper than all this experimenting. Just more research to do!
Thanks for all the food for thought, I'm gonna read back it through everything more carefully and see if I have a few minutes tomorrow to do some calling around.
