Health & Medical

The limp showed up a week after a walk through long grass, a small favouring of the front leg that I blamed on a stone, and the test came back positive for Lyme before the lameness had even settled. Lyme disease in dogs is a tick bite that keeps giving, and the gift arrives long after the tick is gone.

The bacterium travels in the gut of a deer tick, and the tick has to be attached for a day or two before it passes the bug on, which is the window where a tick check would have saved us. The dog picks it up in tall grass and woodland, the tick feeds, drops off, and the infection settles in, often silently, for months, until something tips it into a lameness that shifts from leg to leg, the joint warm and sore one day and fine the next. Mine moved from front to back and back again, the kind of wandering limp that finally sent me in, and the blood test confirmed what the grass had started.

The tricky part is that Lyme is not always the cause of the limp. Many dogs test positive and never get sick, carrying the antibody like a souvenir, and the vet has to decide whether this lameness is the disease or something else wearing the same coat. The positive test plus the shifting lameness plus the response to treatment is the diagnosis, and the treatment is a course of antibiotics that usually clears the acute signs fast, sometimes almost suspiciously fast, the dog sound again within days of the first pill.

The deeper worry is the kidney. A small fraction of Lyme-positive dogs go on to a serious kidney inflammation that can be far worse than the lameness, and that is why a positive dog gets a urine check even when he seems fine. Mine dodged it, but the urine test became part of his annual, because the late version of this disease is the one that ends badly, and the early version is a limp you can fix.

Prevention is the whole argument

The lameness was the lesson, but the tick was the cause, and the cause is stoppable. A monthly preventative that kills ticks before they transmit, a check after every walk through grass or woods, a quick run of the hands over the warm spots behind the ears and between the toes where ticks love to hide, these are the habits that mean the next walk does not end in a positive test. I became religious about it, a five-second pat-down that has caught three ticks since, each one removed before it ever bit.

The vaccine exists for dogs in tick country, and the vet offered it after the infection cleared, a layer under the preventative for a dog that clearly frequents the wrong grass. I took it, because a dog that has had Lyme once can have it again, and the bug does not grant immunity, only a bill and a course of pills. The combination of drug, check, and vaccine turned a recurring risk into a managed one, and the walks continued, because a dog that cannot run through long grass is a dog missing the best part of his week.

I would not wish the scare on anyone, but it reframed the tick from a nuisance to a hazard, and that reframing is the cheap part of the cure. Check the dog, treat the dog, vaccine the dog if the country calls for it, and the bite that keeps giving stays a bite that gave up. Mine runs the same fields now, sound, and the only reminder is the annual urine test and the five seconds I spend on his ears every time we come home.

The grass is now a managed risk rather than a free one. I keep him on the path where I can see the ground, avoid the long unkempt verges in tick season, and the preventative goes on the same day every month like clockwork, because a missed dose is the gap a tick exploits. The tick check became a habit I do without thinking, a run of the hands over the warm spots while he leans into it, and it has caught three since the infection, each one removed with a twist and a tick hook before it ever bit. The hook matters, because squeezing the body pushes the bug into the dog, and a cheap pair of tweezers done wrong is worse than no check at all.

The part I did not expect was the relief of knowing. Before the positive test, every limp was a mystery and a worry; after it, the lameness had a name and a treatment, and the dog that had been vaguely unwell became a dog with a managed condition and a clear path. Lyme is not a death sentence, it is a wake-up call with a course of pills, and the wake-up call was cheaper than the alternative would have been. He runs the same fields, sound, and the only reminder is the monthly dose and the five seconds I spend on his ears every time we come home from the long grass.
