I actually don't care much for sprays, in general - there are much better options for flea/tick control in dogs. My favorites are oral medications like Nexgard or Bravecto, but a Seresto collar or topical medication like K9 Advantix can also work well.

If you really want to use a spray, I would suggest Frontline spray - it isn't always terribly effective for fleas, in my experience, but works well for ticks and should be safe. Many of the other over-the-counter sprays contain very harsh chemicals that can be dangerous, so I don't usually recommend them unless you have no other choices.

Yes, I would use better drops for your dogs. The cheap ones don't work as well because the active ingredients are not as strong as the ones you can get from the vet. I don't recommend using Frontline because I personally have seen resistance to it, as have colleagues of mine. I recommend using Advantage or Revolution, but as an oral flea treatment, NexGard is good, as well as Comfortis and Trifexis.

If you want an over-the-counter product, go with Frontline but there are issues with resistance to this product. Otherwise I recommend to call your veterinarian and discuss one of the top products such as Simparica or Nexgard. I hope this helps and enjoy your trip.

Do flea and tick shampoos and sprays work? What are affordable alternatives?

Unfortunately, I have not seen good success at all with any flea/tick shampoos or sprays - in addition, many of these products can be toxic, so I don't recommend them. If costs are an issue, you should be able to get K9 Advantix fairly inexpensively over the counter - this works well for most dogs, and costs less than prescription products. A Seresto flea/tick collar is also a reasonable option - it's a bit more expensive up front, but provides protection for eight months so per month, it's one of the least expensive options available.

My dog has fleas. Are flea collars effective, or are oral meds better?

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.

Spot ons: Revoulution Advantage Advantage Multi Frontline (ticks as well) Tablets: Trifexis/comfortis Bravecto (ticks as well) - for dogs Collar: Seresto ( (ticks as well) House spary: Indoorex

What's the best flea control for my dog: topical, collar, or chew?

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.

What flea and tick products are dangerous or toxic for dogs?

I occasionally see toxicity issues with some of the over-the-counter topical flea products like Hartz, Sergeant's, etc. - this is more commonly a problem in cats, but can sometimes be an issue with small dogs as well, especially if they've been dosed above their weight range. All of the prescription flea/tick medications currently on the market (Bravecto, Nexgard, Simparica, etc.) are quite safe and effective.

What's the best way to protect my dog from fleas: natural or products?

Natural products just don't stand up to pests like fleas and it will leave you very frustrated as a pet owner trying to get rid of them. J would stick with a good quality flea preventative such as Bravecto, Nexgard, Simparica or Comfortis. Frontline has largely grown out of favor because it has been ineffective in a lot of pets. The only over the counter product that may work in my opinion is Advantix or Advantage multi. Best of luck with your flea problems and I hope you get some resolve soon.

My dog has fleas. What's the best treatment? Are flea collars safe?

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.
