Can my 90lb Rottweiler safely use a 4% deltamethrin flea collar?

I did a little bit of digging to be sure that I'm up to date on the most recommendations for using doramectin in combination with other products. It looks as though parasitologists say that it is safe to use topical flea and tick medications or a Seresto collar during Doramectin treatment. Personally, I don't find the Vetriscience product to be very effective, so you would probably have better luck with over the counter products like topical Advantix (a "drip" treatment) or a Seresto collar. I hope that everything goes well for Janjan!

I don't think you are going to get a clear answer on this. I've included the company's drug information below. https://merckusa.cvpservice.com/product/basic/view/1047301 Their recommendation is to consult with your veterinarian if your dog is pregnant. I have looked for any information about this product in pregnant dogs and cannot find any which likely means that there hasn't been any testing done. So, the answer is that we likely just don't know if this is safe for pregnant dogs. There are flea and tick products that are listed as safe for pregnant dogs, so I would consult with your veterinarian for a recommendation. Good luck! Thanks for using PetCoach.

So Flumethrin is used to kill ticks, and Imidacloprid is used to kill sucking insects such as fleas. This collar is safe to use on Oscar, but like any treatment, there are potential side effects. These include slight hair loss and irritation at the site of the collar. Seresto have been vigorously tested for safety, so you can use it on him without worry. I hope this helps!

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.

The only decent flea collar is seresto. It is labeled for 8 months but the more you bathe them the shorter that period seems to be. So realistically you can get 5-6 months out of it. Bravecto tablets work well as it can last 3 months

Flea collars do not work very well and some are toxic if ingested. I don't recommend using them on puppies, in case it falls off and the puppy tries to eat the collar. I recommend using a monthky product, like NexGard, Frontline, Advantage, or Revolution. You will also need to treat your house with an appropriate flea product.

The Seresto collar is available for any dog under 18lbs. You will require the small dog collar. These collars last eight months and kill fleas and ticks. In my opinion, they are the best thing around for prevention. This is particularly important for your, as you are living in Reading, which has an extremely high population of lyme-infected deer ticks. If you plan on allowing your dog to be submerged in water for any length of time, you should remove the collar. If you do not, the collar is still good but will only last for five months.
