Seresto Large Dog

Seresto Collars are for the treatment and prevention of fleas in dogs and cats and for the protection against tick infestations. The collars can also be used as part of the treatment for Flea Allergy Dermatitis.

They are a grey, odour free collar supplied for cats, dogs 8kg and under and dogs over 8kg. They provide protection for up to 8 months. The active ingredients are imidacloprid and flumethrin.

Why Seresto? Unlike other flea treatments, Seresto releases it's active ingredient at very low doses which means the protection can last between 7 and 8 months. Once the collar is applied to your animal's neck, you do not need to do anything else until the 8 months is up and then the collar is simply replaced. This means you do not need to remember your monthly applications!

How to apply a Seresto Collar:

. Remove collar from the 100% recyclable tin and pouch. Detach plastic remnants from collar

. Put the collar around your pet's neck and push the end through the loop

. Tighten up the collar until there is a 2 finger width distance between the collar and your animal's neck

. Any excess collar should then be cut off

In growing pets, additional collar length should be left on so it can be adjusted accordingly.

Ideally, the collar should be applied before the beginning of the flea or tick season.

This is a prescription item and will be sent once a valid prescription is received.

If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.

Offer of 3 different delivery options yet when it came to check out process website would allow me to change so I ended up with extra charge for express delivery which I didn't need
Also offer of payment was taken away - PayPal was one of the options yet again was nowhere to be seen once I started check out procedure
only good thing is you can place repeated order so don't have to worry about running out if you forget to buy

Dear Romana.

Thank you for your feedback. Whilst we offer Royal Mail 1st and Second Class as an option for most products, we do state on our delivery pages that Food orders over 2kg will be sent out via courier as they are heavy items. As a result Royal Mail 1st and 2nd Class are not presented as options when a food item over 2kg is added to your basket. This is to ensure that we offer the most competitive delivery price to you as the shipping costs are lower than Royal Mail and also have the added benefit of being guaranteed next day with a one hour delivery slot which our customers greatly appreciate.  We also offer free deliveries on food orders over 6kg. As I am sure you can appreciate delivery options have to vary for this reason and you have not paid any extra charge as it was the cheapest option available.

The Paypal option is normally present for most standard orders but not for regular orders like the one you placed as we are unable to process repeat Pay Pal transactions (and Pay Pal transactions also have a 2.5% surcharge to cover the extra processing charges we incur with Pay Pal which not all customers want to pay and are happy using their normal credit card as a result).

I hope this expains matters but please do not hesitate to contact me on if I can be of any further help.

Kind regards

Jon (E-Commerce Manager)

Thank you for your reply Jon - my apologies for not reading delivery options properly - as for PayPal I'm surprised about that extra cost and fully understand why it's not an option

Feel free to take my unkind review off your site

Kind regards

Extremely fast delivery of quality products


always fast and excellent service


Easy to use website - good information - cheap prices


great value for money and no hassle at all


Shocked that I could buy medication for my dog so cheap. Order was delivered promptly will definately be using this company again, nice to browse products from comfort of home instead of going to pet stores where you can get into a minefield of similar products without knowing if it is the right product you need at the time.


good reliable and swift service. I would recommend to friends and will be ordering from you again.


Great price and super-quick delivery...thank you!
