Is it normal for my dog to have a flea after monthly prevention?

It might be a flea that jumped on him after the application, this can happen but if you find more than one and they are alive then the product you are using is likely not working and you need to change it to something else such as Bravecto, Advantage or Revolution.

If you’re noticing increased itching in that area and you found a flea, you may try switching the flea prevention to see if that helps. Fleas can become immune to products. The top products on the market are oral products such as Nexgard and Simparica. Most pets can use these products but you should talk with your veterinarian before switching. They are administered once a month and at this point appear to work very well. If the itching goes away, then you know it was related to flea bites. Best of luck.

It is safe to reapply the Frontline now, but in my experience, it doesn't have great flea protection. You may have better luck with Advantage products or a Seresto collar. The best flea protection is the prescription oral flea preventatives, like Bravecto or Nexgard.

Unfortunately toward the last week of the month these ampules sometimes wear off, meaning your dog can have fleas and the fleas can lay eggs, but as long as you treat him regularly those eggs and any reaming fleas will be killed.

I would refrain from reapplying this topical product, because you cannot be sure how much of it was rinsed off and it is best to not overdose him. Also the biting and scratching can be normal for any pet that has just received flea preventative if there was a large infestation of fleas. The "itch cascade" as we call it can last even after the parasites are gone, and often pets require a short course of steroids or a steroid shot to stop the itch completely. Your best option at this point, if you still see evidence of fleas or ticks, is to follow up with a medication called Capstar. This is the only flea ridding product that can be used in conjunction with topical flea preventatives, because it does not last in the pets system very long. You can safely redose the Pet armour in 2 weeks time. However I will say I am not a fan of this product and find there are better, more effective ones on the market. For instance, Bravecto, Nexgard, Advantage Multi, just to name a few.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Fleas can be frustrating to eradicate even when using a quality product like Bravecto. You may wish to consider a product like Capstar or even a topical flea medication in addition to the Bravecto. Products like Frontline Gold, Vectra and Advantix tend to work well. The flea life cycle sometimes necessitates that you also treat your household and even your yard to fully eradicate the infestation. Regular laundering of pet bedding can help but you may still end up needing to have an exterminators help. Finally, make sure all pets in the household are treated with a safe, quality flea preventative as often house cats that have not been treated can harbor fleas. Good luck!

Bravecto is generally a very good product and at this point, especially with not seeing any fleas, it’s unlikely that they are the cause of itching. I don’t recommend to apply another product or to give the Bravecto early. Pets can be itchy for many reasons. Itching on the feet can be a sign that she walked through a chemical or plant that may be causing an allergic reaction. Also try to recall if she has had any new foods or treats as that could cause itching too. Lastly, environmental allergies can flare up when our homes are closed up in winter time with the furnace circulating large amounts of dust, dust mites and other indoor allergens. At home you can start her on an omega 3 fatty acid supplement for dogs, this will help improve skin health. You should also call you veterinarian and ask about antihistamines or if they think she needs something stronger. Bathing her in a oatmeal dog shampoo and conditioner can also help decrease itchiness. Most dogs can be bathed once a week. I hope this is helpful and please feel free to post any additional questions.
