Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 30 lbs

Hello, I am wondering what type or brand of flea collar you would recommend for dogs? Additionally, would you suggest flea collars with natural based ingredients, such as resin power and citronella or collars what utilize active chemical ingredients such as imidacloprid and flumethrin? Thanks in advance for any help.

If you'd like to use a flea collar, I'd recommend Seresto. It's a good brand of flea collar, and while I personally do not like flea collars, it's one of the few I'd recommend. I do not like flea collars because I find them to be less effective than a spot on treatment, and they can and do cause skin irritation and rash. Flea collars with natural ingredients do not work at all, and I never recommend them. You need one with chemical ingredients to kill the fleas. If you are interested, I can give you the treatment program I always recommend. First, I would give Sam 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. Good luck, I hope this helps!

Hello my dog jack russell terrier has fleas and I need to know what do I need to use to get rid of... I want to buy a collar but I am not sure if it won't be too strong for her.....
The only flea collar that appears to work well is the Seresto collar. And even then, I can have a slower rate of kill for the fleas. The top products on the market our oral products such as some Perica and next guard. For most pets, these are good options that I recommend to call your veterinarian first and doublecheck. Also, you will need to treat all the pets in the household for six months to make sure you get through the entire fleet lifecycle. Best of luck.

I put a soresto flea collar on my dog that doesn't seem to be working. Can i put activyl topical on him as well?
No, it's not recommended to combine those. Take the Seresto collar off, and I can give you a flea treatment program for Indi. 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.

Are flea collars useful? I have a cheap one $5 Adams brand but I wonder if it's worth $52 for a name brand one. Dog recently had fleas and switched to Advantix from PetArmor but wondering if the extra step is necessary?
The Seresto flea/tick collar is the only one on the market that is safe and effective - the others, including Adams, are often dangerously toxic for the dog and not effective at all for fleas in my experience. Advantix is definitely a better choice than PetArmor, but the most effective option available for fleas and ticks currently would be an oral medication like Nexgard or Bravecto. I would recommend getting a prescription from your veterinarian for one of these medications, if possible - this will eliminate the need for any topical medication or flea collars, and will also work much better.

How to get rid of fleas on our small dog without the guard medicine they put on their back? Is a flea collar good?
Comfortis (tablets) is what I would recommend as very effective and reliable. Otherwise here is a list of good quality flea (and ticks) treatment. Spot ons: Revolution, Advantage, Advantage Multi, Seresto ( collar) (ticks as well). Personally I don't recommend collars as they are less reliable in terms of efficacy. A good house spray would be Indoorex. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi I was wondering what flea medication works the best my morkie puppy is 13 weeks and we got a flea collar and spray her with once a day medicine and she had multiple flea bumps along her neck and head and it's just in those areas and it's bad in my
Great question! Flea collars are not very effective, as you are seeing unfortunately. I can give you an effective flea treatment program for Indy. First, I would give her 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, as it will be a continuing source of fleas if you don't. Wash her 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. I hope this helps!

Do you prefer Modesto collars or frontline topical for flea control?
I prefer spot-ons and chews over collars. The only collar I would recommend is Seresto. This, in my opinion would be superior to Frontline, as in many areas there are resistances to Frontline already.

I live in Florida what do you recommend for flea treatment? I tried the Ceresto collars it worked at first then nothing.
I recommend oral flea & tick preventatives. There are several brands, and all are effective: Nexgard, Simparica, and Credelio are monthly, or Bravecto which is given every 12 weeks. My top two are Nexgard and Bravecto. These are prescription products available from your veterinarian. Hope this helps!

Hello! Do you recommend flea collars? I hear more cons than pros and I wanted to get a professional opinion before I get one for Mia?
I think that certain flea collars can provide good protection against fleas and ticks for the right dog in the right area. Seresto is the product that I most often recommend. The collar has to stay on all the time, and bathing or swimming can alter the effectiveness of the collar, so if Mia is frequently in water or you don't want her to wear a collar all the time it might not be a good choice. Preventic is another collar, but there is concern for toxicity if the collar is ingested and there may be some concern if there are children or pets in the house that will be chronically exposed. I have also seen over the counter collars that have essential oils or pyrethrins as the active ingredient - in my opinion these don't work well. Your best bet is to ask your vet which collar they think would work best in your area.

What type of product do you recommend for flea and tick control? I don't want to give my dog a oral medications and I've tried seresto collars but he got fleas and ticks anyways.
I can give you the flea treatment program that has always worked for me. First, I would give Oscar 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.

What do you think about "natural" flea collars for cats as a substitute for those made with insecticides? What cat flea collar do you recommend, if any?
Unfortunately, there is no evidence that any of these "natural" alternatives work well for fleas, and I have never seen any of my clients have much success with them. If you want to use a flea collar, I would recommend the Seresto collar - it's safe and non-toxic, and is usually quite effective for both fleas and ticks.
