Unlike other flea and tick protection, Seresto Large Dog flea and tick collars kill and repel fleas and ticks for eight continuous months. Seresto Large Dog flea and tick collars are recommended by veterinarians, stocked by 8,000 vet clinics* and have been trusted* by pet owners for nearly a decade. *Elanco Animal Health, data on file Seresto Large Dog flea and tick collars are for dogs at least 7 weeks old, and there’s no prescription needed. They’re odorless, non-greasy and water resistant to swimming, exposure to rain or sunlight, bathing, and shampoo treatment.** **Seresto Large Dog is water resistant and remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight. Under normal conditions, effectiveness lasts for 8 months. In order to maintain an eight-month duration, dogs must not be bathed more than once per month. For dogs that swim once a month or more, the control duration is reduced to 5 months for flea control and reduced to 7 months for tick control.

How does Seresto for Large Dogs work?

Seresto Large Dog collars make your dog’s comfort a priority by killing fleas and ticks on contact, so pests don’t have to bite your dog to die. Existing fleas die within 24 hours after initial application of the collar. After 24 hours, any new fleas on the dog are killed within 2 hours with protection against further flea infestation lasting 8 months. The prevention of infestations with new ticks starts at 48 hours after application of the collar. 48 hours after application, any new ticks are repelled and/or killed in as quickly as 6 hours. Seresto Large Dog collars protect against common pests like deer ticks, American dog ticks, brown dog ticks, and Lone Star ticks; they’re also effective against chewing lice. Fleas and ticks not only cause discomfort; fleas can transmit bartonellosis or tapeworm. Ticks can transmit Borrelia burgdorferi which causes Lyme Disease. Check the product label for information on potential side effects.

Cautions:

The collar should not be used on puppies younger than seven weeks old or on kittens younger than ten weeks old. If ticks are present on your pet when the collar is applied, they will not die within the first forty-eight hours and should be removed manually. If your dog or cat shows any sign of skin irritation or other reaction to the collar, remove immediately and consult your veterinarian.

Do not allow children to play with collar or reflectors, or to put them in their mouths. Avoid contact with eyes, skin or clothing. Wash thoroughly with soap and water after fitting the collar. People with sensitivity reactions to the ingredients of the collar should avoid contact with the collar. Choking hazard. Contains small parts. Do not place reflectors in mouth. Not intended for use on humans.

Storage:

Store in a cool, dry place away from children.

Only time will tell
[This review was collected as part of a promotion.] I placed the collar on my dog but I can't attest to whether it is currently working or not. I live in Michigan and it is january. There is snow on the ground and it's very cold out meaning there are no fleas or ticks to be found. The size fits my dog and the material is easily clean able ( although I am curious of how effective it is if you have to still clean it off due to getting dirt or other materials on it.) It claims to work for 8 months so you would leave it on your dog for 8 months and if an active dog, it's bound to get dirt or grime on it. I'll be curious to see how it works at the summer and hot weather comes.

Promising
[This review was collected as part of a promotion.] I live right next to a wooded area with deers so my dog frequently has ticks during spring and summer time. I received this product in January so I’m not sure how well it tests out. I have read very good reviews on it. I like how it doesn’t smell like anything and doesn’t feel greasy. I wouldn’t want to put anything like that on my dog.

Easy to put on and made to fit
[This review was collected as part of a promotion.] I wish I had more time to give this review because it’s difficult to tell the effectiveness of it during this time. However, I can say, so far, my dog has had no issues with fleas since he’s worn it. It’s super simple to put on dogs, way easier than cream or shampoo. The size is adjustable, which helps when you don’t really know the neck size. Hopefully it continues to help.

Husky approved
[This review was collected as part of a promotion.] Having good flea and tick prevention is important for my husky, his fur is so thick. He can be a little picky with what I put on him, it has to feel comfortable. So far so good! He has tolerated this collar very well and his scratching has gone down considerably. This is turning out to be a really good option for bug control.

Works great.
[This review was collected as part of a promotion.] The flea and tick color was easy to put on our dog. I noticed after a couple of days he hasn’t scratched himself. The provider seems to work effectively for keeping fleas and ticks off.

Works well for my large dogs
[This review was collected as part of a promotion.] This works great for my dogs. I don’t have a huge issue with ticks, but I do have an issue with fleas and this really seems to help. I’m not a fan of flea collars in general because I’m afraid of the chemicals rubbing on me cause I sleep with my dogs, but so far this hasn’t bothered me!

A summer of no ticks YES please!!!!
[This review was collected as part of a promotion.] I already love Seresto. For my 92 lbs lab mix. It does aggravated his skin. When he has a scratch it doesn't impact it at all no matter how much or how hard he scratches his neck. And no weird smell like other flea colars.
