Lyme disease and dogs (long)

Ok, so this isn't really a nursing post, but I figure we're all pretty smart folks here, so here goes! Does anyone have any experience with lymes and dogs?

My french bulldog has had anorexia, lethargy, non-specific type pain (such as with petting), and acute joint pain. He's been to the vet three times in the last week, and they can't seem to find a cause. They did general labs, BMP, CBC, renal and liver function tests and all were normal. He's also afebrile.

Tonight it occured to me he seems to have acute pain in different joints, and arthritis. Then it hit me...Lymes! So, does anyone know if he could have Lymes, with normal labs and be afebrile?

I'm not asking for medical advice, at least not for OUR type of patients! More like anyone's experiences with their dogs and lymes. I plan to try and beg the vet for some doxycycline in the morning. Thanks for taking the time to read this!
