My French Bulldog has fleas. Can I give him Comfortis for treatment?

Advantus chews or CapStar may be options for flea control. The only drawback is that they are given daily. Comfortis, Credelio or Trifexis are probably your best options as they are more effective that the daily chews.

Nexgard is an excellent product that provide tick protection in addition to flea prevention. Bravecto is a similar product, but it provides coverage against fleas and ticks for 3 months. All of these medications require a prescription. I would recommend discussing them with your vet to determine the best fit for Charlie.

These two medications work in different ways, and it should be fine to give Frontline now. You may also want to ask your vet what they would recommend as the best flea preventative in your area if you’re seeing fleas despite using Advocate.

Comfortis is a great product and should start killing fleas within 30 minutes. If you are still seeing fleas there are a few things to consider. First, make sure you give the Comfortis on a full stomach and make sure the dog keeps it down (sometimes dogs vomit after taking it). There are also probably fleas in the environment/home. I would recommend vacuuming all carpeted areas in your house and washing all of the pet's bedding. Even with the best flea control it can take up to 2-3 months to get the flea problem under control. Make sure you treat all the other pets in the household as well

Hmm - it's odd that the Trifexis doesn't seem to be working as well, because it actually has the same active ingredient as Comfortis. The only difference is that it has an added ingredient for heartworm prevention, otherwise it's exactly the same drug. In my experience, both are extremely effective for fleas. I wonder if perhaps Tessa is continuing to pick up fleas from somewhere in the environment? It does take a few hours for a flea to die after biting her, so if she is continually being re-infested from the house or yard, it's very possible that you might see live fleas on her even if the medication is working properly. If you think this might be the case, I would recommend treating your house and yard with a premises spray such as Knock-Out. If you still want to get her something else for fleas, I would not recommend giving a Comfortis dose on top of the Trifexis, because this would just be giving a double dose of the same drug - I would be concerned about possible side effects from overdosing this medication. Instead, you could consider using a topical flea medication this month such as K9 Advantix, since this is a completely different medication that doesn't interact in any way with the Trifexis.

You will need to go to the vet to get the following products. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30. minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home.

Comfortis is a prescription product so you will need to see your veterinarian. If you can has been examined within the last year, they may be able to approve the medication for you. You will also need to call your vet for pricing. It's typically cheaper per dose to buy it in a 6 months supply rather than a single dose. Ask if any rebates are currently running as this could help as well. To fully get rid of fleas, you will need to treat all the pets for 6 months. I hope this helps.
