Ticks

Far be it from us to tell you to put pesticides on your dog. But we’ve never heard of a single nontoxic preparation that was effective at keeping ticks off all dogs. For some dogs, only the potent pesticides seem to keep ticks away. There are, however, some nontoxic products – both commercially produced and homemade formulas – that work to repel ticks well enough to consider using them as part of a comprehensive Lyme disease prevention program.

Lyme disease affects thousands of Americans and their dogs and horses each year. Named for Old Lyme, Connecticut, where it was discovered formally identified in the 1970s, Lyme is a regional disease, with 90 percent of its cases in New England and the Middle Atlantic states. The rest come from the upper Mississippi (Wisconsin and nearby states) and parts of California and Oregon. A few dogs and people with Lyme disease live elsewhere, but they are believed to have been infected during travel or, in some cases, by ticks from migrating birds. Veterinarians in the Northeast know Lyme disease well. Its symptoms are very noticeable in dogs

It’s creepy enough that there are billions of these tiny insects living in the woods and fields, just waiting to latch onto your dog...

Is it my imagination, or is a plague of ticks currently in effect? Everywhere I go with my dogs these days, they come back crawling with ticks. I use Frontline on them, though I've used Advantix in the past – as well as apple cider vinegar rinses and essential oil sprays and Skin-So-Soft wipedowns. For whatever reason, Frontline seems to work better than anything else on my dogs, in my area, though I hear contrary reports from other dog owners in other places. I'm seriously considering making a line of Tyvek canine coveralls, instead.

It's hard to say which is worse: running your hand over your dog and brushing against an attached tick, or seeing a tick skitter across your dog's face. Either way, the unwelcome arachnid must go. What should you do?

Lately, it seems like new flea and tick control products have been popping up left and right. I suspect this is due to some of the original patents running out. When a patent expires, other companies can create generic versions of the same product, usually for less money. This inspires the original companies to create new products that they can patent anew. In some cases, new products are introduced because fleas and ticks may be developing resistance to the older products, lowering their efficacy. Most new products, including all those introduced this year, are just new combinations of older ingredients. Here’s a rundown on these new options.

Tick paralysis is caused by a neurotoxin produced by egg-engorged female ticks, who transmit the toxin from their salivary glands to the dog during feeding. The production (and transmission) of the toxin is greatest when the tick has been attached to and feeding from the dog between five and seven days. Five species of North American ticks produce the neurotoxin: the blacklegged tick (a.k.a. the deer tick), American dog tick, Rocky Mountain wood tick, the Lone Star tick, and the Gulf Coast tick. Most North American cases occur between April and June, when the ticks are at their peak reproductive activity.

It’s a good idea to check your dog carefully for ticks after every outing. You may find loose ticks crawling through your dog’s coat....
