It's really unlikely - it sounds like he had wonderful veterinary and pet owner care! Lyme disease typically results in chronic lameness and rarely, chronic kidney changes (mostly Labradors and Golden retrievers), and rarely causes meningitis. If it is meningitis, it's not chronic seizures - it's acute disease. it doesn't sound like it's from Lyme, honestly. I'm glad you were able to rescue him from what sounds like a terrible situation... and being that he lived to 14 (which is very geriatric for a shepherd-sized dog), it sounds like you were taking great care of him! Deepest sympathies.
