The Pros and Cons of Advantix for Your Pet

Flea, tick, and mosquito control for dogs, with caveats

Advantix is a topical treatment for dogs that repels and kills fleas, ticks, and mosquitoes. Many owners use it to keep infestations from starting and to protect their dogs from parasites that can do real harm.

It has clear strengths. It also has drawbacks that weigh more heavily in some households than in others, and a home with a cat is the obvious example. Below are the main points on each side, as a starting point for deciding whether it fits your dog.

Pros

Most of what owners like about Advantix comes down to how much it covers and how little effort it takes.

Effective flea and tick control
Advantix repels fleas and ticks on dogs and kills the ones that do manage to get on. That helps prevent an infestation from taking hold, and it spares your dog the discomfort and the possible health risks that come with flea and tick bites. It is also known for acting quickly, so a dog that already has fleas should usually get relief before long.
Mosquito repellent
Advantix also repels mosquitoes. Where mosquitoes are common, that matters more than it might seem, because they can transmit diseases such as heartworm that are harmful to dogs. A repellent probably won't stop every single bite, but it can lower the risk of your dog picking up a mosquito-borne illness.
Waterproof
Once it has been applied, Advantix is waterproof. It keeps working after a bath or a swim. For dogs that love the water, that means protection against fleas, ticks, and mosquitoes continues without a gap every time they go in.
Convenient application
You apply Advantix directly to your dog's skin. That makes it easier to treat on schedule, and staying on schedule is what keeps flea and tick control effective. There is little mess. You also don't need to get a pill into your dog or keep a collar on it, which many owners find far less of a hassle.
Long-lasting protection
A single application typically protects against fleas, ticks, and mosquitoes for up to a month. You don't have to reapply often, and with fewer treatments to remember there are fewer moments when your dog is left unprotected and uncomfortable because a dose came late.

Cons

The drawbacks are mostly about safety, both for other animals in the house and for dogs that don't tolerate the product well.

Toxic to cats
Advantix contains permethrin, which is toxic to cats. If you have both a dog and a cat, this is the drawback to take most seriously. A cat can be exposed through direct contact with a treated dog or by grooming it, so you have to keep the two animals from that kind of contact to avoid poisoning the cat.
Possible skin sensitivity
Some dogs develop sensitive or irritated skin where Advantix was applied. Keep an eye on your dog in the period after each treatment, looking for signs of discomfort or any other adverse reaction. If you notice something, it is sensible to ask your vet about it.
Not suitable for every breed
Advantix may not be suitable for certain dog breeds, or for dogs that already have health conditions. Known sensitivities or existing medical issues could be made worse by the product. If your dog falls into one of these groups, check with your vet before the first application to find out whether it is safe.
Possible adverse reactions
Most dogs tolerate Advantix well. Some, though, get mild to moderate reactions at the application site, such as redness, itching, or irritation. Watch your dog for a while after you apply it, and contact a vet if a reaction appears.
Age and health restrictions
Very young, elderly, and sick dogs may not be good candidates for Advantix. Dogs with existing medical conditions may also need extra consideration before it is used on them. Your vet can tell you whether the product is appropriate for your dog's age and state of health.

Conclusion

If you also keep a cat, talk to your vet before you buy Advantix, because keeping the two animals apart after every treatment is the price of using it. Puppies, older dogs, and dogs with health problems need a vet's opinion first too. For a healthy adult dog in a dog-only home, the main thing left to watch for is a skin reaction after each application.
