Long story short-
I switched vets, took Carbon (the 3 year old golden) in for a well check on a hunch. For 96 dollars they send out a blood panel and urinalysis. Darned if Carbon did not come back with a UTI, protein in his urine and a low thyroid. Did a free t4 and it was normal. The assumption is that he has another problem as he was asymtomatic,(the last weekend he was in obedience 3 days, picked up dead ducks on Monday) so we are checking for tick diseases as his kidney function is good.
So, he is on lots of drugs, and she is looking into a "new" tick panel Amteck (sp) is offering, which also tests for parasites (sp).
Honestly I am so thankful I did this, because if he had gotten sick, I am afraid we would not have checked for all the other stuff.
I have not picked a tick off of him in over a year, but we were all over the place last summer.
Was he sick? yes. Less than 24 hours after the first dose, he was tearing up stuff and wild. And here I was thinking he was finally growing up
