Ok, home from vet. Full lab panel showed chemistry, cbc and liver studies all normal. Fasting glucose was normal. No signs of any issues there. He does have a rather significant uti (urinary tract infection) for which he will be on antibiotics for the next 3 weeks. This may or may not explain the strange behavior that made me take him in the 1st place. Possible mild seizure disorder was also mentioned, but even if it were, 2 seizures in 4 months does not warrant any anti seizure meds since epilepsy isnt uncommon in dogs and is usually diagnosed between ages 2 &5 years, which he is, & unless he was having seizures several times a week, they wouldnt put him on medications because the adverse effects are worse than the rare seizure. (and he doesn't drive or operate heavy equipment
) I am to watch for any signs of seizure or post ictal behavior & report to them immediately if any noted. No CT scan or xrays needed at this time. And this is just a discussed "something to watch for", not a diagnosis at all, just a possible theory.
So, all in all, good news. He should feel better quickly with the antibiotics. Currently, he is sulking because of the urine specimen being obtained. He got them back, though...apparently he peed all over the people obtaining the specimen, then took a big poop right there, which the vet said also looked good, since he provided the specimen for examination..
He's really gonna be mad in a minute because now, thanks to his antics, his entire backside smells like peepee and the spray they tried to clean him up with, and he is a tangled, curly mess, so into the bath we go!
Thank you to everyone who offered suggestions. I'm glad y'all talked me into going to the vet sooner rather than later. I feel much better now, and Huey should soon.
