The majority of unsuccessful treatments for fleas are the result of the wrong application. While topical treatments for fleas appear to be simple enough, you should follow the directions on the label exactly before applying the product for the treatment to function properly.

The frontline is available in a tiny tube applicator that has a snap-off tip. Remove the tip by hand or split the hair of your pet in the shoulder blades and then apply everything directly onto the area of the skin.

Many pet owners fall for the blunder of applying the medication for fleas to their hair instead of on the skin. The active ingredients must get through the sebaceous (oil) glands in order to move throughout the body.

If you don’t, you’ll get rid of fleas in a single area of hair:

Also, make sure that you make use of the entire tube to get the most effective results.

The frontline takes care to measure every tube for a full 30 days. Therefore, you must take the full dosage to ensure that the treatment will last. It is also crucial to select the appropriate dosage that is appropriate for the pet’s age and type.

You Should Be Using A Different Medication:


If you find that your Frontline treatment hasn’t been working despite all your efforts, it could not be the appropriate medicine for your pet.

Fleas may become resistant to certain active ingredients, so various brands of topical flea treatments are able to be effective in various regions.

It’s a good thing, Frontline can be an excellent option for pet owners across the US. If Frontline isn’t your ideal choice it’s possible to talk with your vet about alternatives to consider.

The Problem Is Coming From Inside The House:

Frontline kills fleas upon contact however, it’s not able to ward off them. If you treat your pet for fleas but don’t also treat your house in the same way, you’re inviting another infestation.

Flea eggs are also able to last for days under almost any weather and hatch only when the conditions are favorable. This allows them time to rest till the Frontline is gone from your pet’s system before attacking.

After you have treated the pet with Frontline and a sanitizer, take your home for a thorough clean to keep the pests from reviving.

In extreme instances, it is possible to resort to chemical solutions to combat your problem with fleas. Spray the areas that are problematic with insecticides or could start from scratch with an expert tent set up and bug bomb your home.

Other Pets Are Bringing In Fleas:

If you own more than one pet it may be the reason that you don’t think of bringing new rodents into your home.

If you are treating only one animal in the home with Frontline it is important to make sure that you treat every other pet in the household as well. Also, you should maintain your hair as well as clothing clear and avoid walking in the areas of brush that could be the home of unwelcome hitchhikers.

Even if you have only one pet in your home, there could be another furry animal that could exacerbate the pest issue. Mice, shrews, and other tiny pests draw fleas and can easily infiltrate your home if they are not taken care of. If you spot indications of a rodent problem make sure you nip it off before you’re faced with fleas all over your home, too.


In Summary:

In the event that the concentration of chemical compounds is too high or your dog isn’t small enough, it may cause some unpleasant negative side effects for your precious dog.

This could include signs like lack of coordination, excessive vomiting, drooling or convulsions, and even seizures! If your dog is showing any of these symptoms in any way, the most effective option is to bring it to the vet right away.
