Can anybody tell me if there are veterinarians that specialize in toxins, or poisonous plants, or something like that?  I'm not finding anything when I search under UW Madison Vet School websites, but maybe I should try calling their vet hospital to see if they can point me in the right direction. 

I won't rehash the whole saga for you (unless, you think it'll help!), but basically my tripawd Gerry (tripawd from injury, not cancer), had strange episodes of fear/anxiety that may or may not have been atypical seizures at the end of May.  I'm sure it was physical, not behavioral, but that's a long story as to why.  Worked with multiple verterinarians and did a lot of different tests to try and figure it out, but everything looked good.  We found several things in the process (tapeworm egg and mast cell tumor were the two most significant), but according to the vets, none of them would have been related to his freaky freak-outs.  No episodes since (though we're struggling with diarrhea that his vet is pretty certain is food intolerance).  In the last few days, I caught Gerry pick off and swallow a berry off what I know now are quite deadly yew bushes (Canadian variety, I think).  Once I got the low down on them, I got them removed ASAP.  Now, I've found descriptions online of symptoms related to yew poisoning in dogs, that I think fit with what I saw with Gerry.  But I'm being told by his regular vet that no, his symptoms don't fit with what her books say about yew poisoning.  Sigh.  I know, I'm probably just in denial that she's right, because A) I want a definitive answer on what happened to him and B) It's so disturbing how many things have gone wrong with his health this year that are allegedly completely unrelated.

So who else can I bother with my denial, please?
