Fantastic. Oscar had serious skin problems from being allergic to flea bites. His skin was weeping and sore. Since buying this collar we have never looked back. He is now a beautiful, playfull, fluffy cat.

I don’t like the thought of the type of tick controls that soak into the skin. I’ve used these collars for a few years now and I think there great.

55 Worked well for us
Verified Purchase

I have 2 dogs and we live in red deer country.
Summer last year was really bad for ticks in our fields and I was taking 12-20 off each dog each time they went exploring; previous years we only had a couple the whole season! It was 20-40 ticks walking on my dogs, I was checking them multiple times a day and missed very few so we had very few latched on.
I bought these collars and they massively cut the number I found on them each day.
This year they have them on already and I hope to see no ticks!
They are pricey but they work.
Fleas aren't an issue for us, I shouldn't speak too soon but we've not had a flea in 4 years.

Seresto flea collar

Jennifer Pettman

How can I be sure your Seresto flea collars are genuine ones as there are a lot of fake ones being sold. Thanks

  • VioVet Staff

We stock all of our medications from licensed wholesalers, the same as your vet would receive supply from. We are one of the Veterinary Medicine Directorate Accredited Retails which means we undergo additional measures to ensure a high quality service is provided. You are right to be cautious as counterfit Seresto Collars have been in circulation but I can reassure you the ones we provide are genuine and made by Elanco themselves.
If you ever receive medication from a source you are unsure of then you can ring Elanco (the manufacturer) with the batch numbers/expiry date of the product. They can then verify whether the product was made by them or not.

Large Seresto tick collar , how long is the sell by date if I buy now.


We usually put a large Seresto collar on our Labrador in February how long does the treatment last, she has it on all the time.

  • VioVet Staff

Seresto collars reaming active, releasing the medication to your dog's skin for up to 7 to 8 months. It is recommended a new collar is applied after the 7 to 8 month mark.

Seresto + advocate

Jill Greenwood

  • VioVet customer since 2015
  • From: West Yorkshire, United Kingdom

I use advocate on my two dogs as they are not reliable tablet takers. Can I use the Seresto collar plus their 3 monthly Advocate, or is that too much in their system. If not is their another spot on for worms i can use in combination with the collar instead either on or off prescription?

  • VioVet Staff

You will be giving a double dose of imidacloprid if you use Seresto alongside Advocate. However overdoses of 5 to 8 times the recommended amount of imidacoprid were tolerated well in dogs in a clinical trial, with no adverse side effects. Seresto also delivers only what your dog needs, therefore it will stop dosing with imidacloprid if you have applied the Advocate, until the Advocate wears off (after 1 month).

Taking the above into account it is likely very safe to use Advocate alongside Seresto. It is worth noting you are not covering tapeworms with this treatment plan though. Unfortunately only tabletable wormers will do this. Please contact us at [email protected] if you would like advice on this.

W Brooks

Is this suitable for an 8 week old puppy?

  • VioVet Staff

Yes this product is suitable for puppies over 7 weeks old.
Seresto Collars last up to 7 to 8 months so I would advise picking a collar size (<8kg or >8kg) based on the weight your dog will grow to be within this time period. If you think your puppy will by heavier than 8kg within 7 months then I would choose the larger collar size.

The collar will need to be adjusted as your puppy grows but this can be done easily. The product itself will only dose your dog with the right amount that they need depending on their current size, so you do not need to worry that a larger collar will give too large a dose.

What wormer should be used alongside this collar?


I was led to believe that only certain wormers should be used, if that is the case what wormer should be used alongside this collar?

  • VioVet Staff

One of the following wormers would work well alongside this collar:

A Wormer containing Praziquantel, Pyrantel and Febantel - this will cover roundworms and tapeworms, routine worming recommended every 3 months. Our own brand TermaWorm is a good example

A Wormer containing Milbemycin Oxime and Praziquantel - this will cover roundworms, tapeworms and lungworm if used monthly. Examples include Milpro, Milbemax, Milprazon

Does my dog have to wear this 24 hours a day?


Does my dog have to wear this 24 hours a day, or just when he’s out to protect from ticks?

  • VioVet Staff

Seresto collars must be worn constantly for 7 to 8 months until the product expires in order for guaranteed flea/lice/tick protection. This is because it takes up to for 48 hours for the ingredients to build up until high enough levels in the skin to kill ticks. The ingredients only transfer whilst the collar is on, removing the colar will allow the protection to fade.

Pregnancy Bitch

Jane Lloyd

  • VioVet customer since 2017
  • From: Devon, United Kingdom

Hi is this collar safe to use on a pregnant/lactating bitch??

  • VioVet Staff


Thank you for your question.

This is not suitable for use on pregnant and/or lactating animals.

Is the collar waterproof?


I'm thinking of using the seresto collar and would like to know if it will be suitable for my spaniel as she swims a lot. Is the efficacy affected by water?

  • VioVet Staff


Thank you for your enquiry.

The Seresto ® collar itself is water resistant. Also, because the active ingredients are stored in and distributed through a layer of oil on the pet's skin, being wet won't wash them away.

Hope that helps,
