From Jennifer Kvamme, DVM, writing for PetMD:
Not only are these blood-suckers nasty to look at, all filled up with your pet’s hard won blood as they are, they are also notoriously difficult to dislodge, making it so you have to get up close and personal in order to assure success. Because left too long or not removed entirely, these buggers can cause some serious diseases. So, what can you do to keep your dog tick-free this season? Here are a few ideas to consider:
Using an over the counter spot-on medication that you purchase from your veterinarian, pet store, or online can be a very effective method for controlling both ticks and fleas. These medications are effective at keeping parasites at bay for up to a month. While these medications are great, you still need to be very careful about which one you use. Make sure you read all labels carefully, and if you have any doubts, be sure to get advice from your veterinarian before application.
Pills that are given once a month are readily available for dogs. These medications can work to kill both ticks and immature fleas and will disrupt the life cycle of fleas. They are easy to give and you won’t have to be concerned about small children and cats coming into contact with dogs immediately after application, as you might with spot-on treatments.
Bathing your dog with a shampoo that contains medicated ingredients will generally kill ticks on contact. This can be an inexpensive (though labor-intensive) method of protecting your dog during the peak tick season. You will need to repeat the process more often, about every two weeks, as the effective ingredients won’t last as long as a spot-on or oral medication.
A dip is a concentrated chemical that needs to be diluted in water and applied to the animal’s fur with a sponge or poured over the back. This treatment is not meant to be rinsed off after application. The chemicals used in dips can be very strong, so be sure to read the labels carefully before use. You should not use a dip for very young animals (under four months) or for pregnant or nursing pets. Ask your veterinarian for advice before treating puppies, or pregnant or nursing pets.
Collars that repel ticks are an additional preventive you can use, though they are mainly only useful for protecting the neck and head from ticks. The tick collar needs to make contact with your dog’s skin in order to transfer the chemicals onto the dog’s fur and skin. When putting this type of collar on your dog, you will need to make sure there is just enough room to fit two fingers under the collar when it’s around the dog’s neck. Cut off any excess length of collar to prevent your dog from chewing on it. Watch for signs of discomfort (e.g., excessive scratching) in case an allergic reaction to the collar occurs. Make sure you read the labels carefully.
Another method of topical medication, tick powders work to kill and repel ticks from your dog. These powders should be used with care during application. Be sure that the powder you are using is labeled for dogs before use, as well as for your dog’s specific age. Also, make sure you check the label to make sure that the product is designed to kill ticks as well as fleas. This very fine powder can be an irritant to the mouth or lungs if inhaled, so use small amounts and slowly rub it into the skin. Keep powders away from the face and eyes when applying. You will need to reapply the product more often, about once a week during peak season. Some powders can also be used in areas where your dog sleeps, and in other parts of the household your dog frequents.
Another topical application of medication, tick spray kills ticks quickly and provides residual protection. Sprays can be used in between shampoos and dips, and when you are planning to spend time out in wooded areas — where ticks are most prevalent — with your dog. Be careful when using this product around your dog’s face, and do not use it on or around any other animals in the home.
Keeping your lawn, bushes, and trees trimmed back will help reduce the population of fleas and ticks in your backyard. If there are fewer areas for these parasites to live and breed, there will be fewer of them to be concerned with. If you still have a problem, consider using one of the various household and yard sprays or granulartreatments that are available from your veterinarian, pet store, or local garden center. Just be careful when using these products, as they can be harmful to animals, fish, and humans. If you have a severe problem or you are concerned about the proper handling of these chemicals, you might want to consider hiring an exterminator to apply yard and area sprays to control the ticks and fleas.
After a romp outside in areas where ticks could be lurking, be sure to carefully check your dog for ticks. Look between the toes, inside the ears, between the legs (in the “armpits”), and around the neck, deep in the fur. If you find any ticks before they have had a chance to attach and become engorged, you may have prevented serious illness for your pet. If you do find a tick attached to your dog, removal should be done immediately and carefully, making sure to get all parts of the tick’s body removed from the skin.
While you do have to take your dog outside a few times a day, it is probably not a good idea to allow him to stay outside for extended periods during the height of tick season. Preventing your dog from roaming through wooded areas where ticks are likely to be lying in wait is a very effective way of keeping your pet safe from exposure, but you will still have to check your dog over thoroughly, even after short walks through grass and brush. You may still have a few ticks wandering around your yard, but if you keep things tidy and use preventives for when your dog does go out and check your dog over for any rogue ticks that might have attached themselves, your dog should have minimal risk of becoming a meal for ticks this summer.
