How it works:
The flea and tick collar releases the two active ingredients in low doses over an extended period of time. The ingredients are then absorbed through the fatty layer of your pet's skin and distributed throughout your pet's body to protect against fleas and ticks for eight months. Seresto can be worn alongside your pet's regular collar.
No matter if you have a cat or a dog, the collars come with a rachet release mechanism that releases when your pet is under pressure, which enables your pet to free himself or herself. It also has a pre-determined breaking point if your pet's head and neck get trapped, which allows your pet's strength to break the collar and get out of a sticky situation.
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.

Doesn't work on ticks with Giant breeds
I bought this product specifically for my 6 Great Danes. I'm finding ticks on a daily basis, including large ones attached UNDERNEATH the Seresto collars! It's not repelling or killing them at all. It may work fine on a smaller dog, but I am very unhappy with how much I spent on these and they are not working.
Wonderful and safe!
I have this collar for my dog and cat. I have two little girls and have had great results. This collar is safe around kids and wonderful flea control for the pets! I won't ever buy anything else!! Love it love it love it!!
the collar is a great buy
i love this collar i have 3 inside dogs and its great not to worry about them carrying . fleas in the house
Seresto collar no longer working
Last year was the first year I used the collars; they worked GREAT! I bought 3 new ones and applied them about 1 month ago and my 2 dogs and cat are itching and licking like crazy. I am seeing live fleas on them. The collars are all adjusted per directions. Now I have to figure out an alternative to use.
My dog had fleas before I put this collar on her. It's been two and half months and I seen no fleas on her. I would buy this product again.
Thank you for your question. Bathing will not reduce the effectiveness of the collar however it will shorten the life span of the collar. Instead of 8 months of protection, it may be reduced to 6 months.
