I mean, it’s not out of the realm for something like this to induce laminitis, but I’d think (and hope) vet would have mentioned if he had developed signs of laminitis overnight. I know the irregular swing you’re talking about - currently I’ve attributed it to the weak/arthritic stifles and a bit to the pretty straight nature of his hind leg conformation. But it could be a neuro clue too. At any rate, it was present prior to all this.
@starsandsun funny, when I mentioned the lame leg to the vet last night she said ‘let’s focus on getting this under control and then we’ll worry about the leg, I’ve seen horses come in lame with colic and the lameness resolved once the colic was treated’. Except… if you’re desperately looking for any source of pain to explain his condition, why would you not consider checking the leg he is dead lame on, that has an ankle the size of a softball and a strip of hard swelling along the cannon? Even if that turns out to be just a localized reaction to the rabies, I feel like it’d be the first logical stop after all the colic-related things have been checked out when looking for pain.
I have done a lot of googling on vaccine reactions and specifically rabies reactions in horses, as well as COTH searching. From the info I’ve gathered, his condition really isn’t significantly atypical of a severe reaction. Once he’s hydrated and the ‘colic’ appears to be resolved, it’s really just pain management until the reaction subsides.
Anyway, I’m just over here waiting to hear how the 2nd attempt at a belly tap went, and what’s next. Those of you who have had to deal with reactions before, did your vets report anything to the manufacturer? Were any of your treatment costs reimbursed? I need to go research that avenue.
