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.

Seresto is a prescription item and will be sent once a valid prescription is received. Please follow the instructions given by your vet.

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.

Great service and delivery. Products turned up in great condition.


I ordered Royal Canin Veterinary Diet Urinary Wet Feline CHICKEN in box of 48 Sachets. Next day, I received correct product - but BEEF flavour. I was most concerned that an incorrect product had been sent as this is a Veterinary Diet! As I had opened the box without realising that it was the wrong variety, I was told that they could not accept its return. After explaining that I would not expect them to make such an error when picking a Veterinary Diet from their stock - and having checked with the Manager - I agreed to order another box of the Chicken variety and keep the Beef variety to save having the inconvenience of the return procedure.


Excellent service. Ordered my product through their easy to operate website n it arrived very quickly.


Excellent service next day early deliver

Delivery next day


excellent price, delivered quickly


I always recommend pet drugs online to my many doggie friends,always reliable and helpful and always at a super. price


Prices are good but the delivery timeframe with royal mail is way off pet drugs state 3 to 5 working days for second class when second class is 2 to 3 days they seem to be very slow in dispatching the goods which is why they add 2 days onto the delivery its wrong every time I order from other companies with royal mail second class its here in 2 days not 4 days later.

On 22 Aug 2016 Pet Drugs Online responded:
Hi Andrew, I was sorry to see this. We dont priortise Royal Mail 1st over 2nd - it all goes out the same day and then we are in the hands of Royal Mail. We adverstise 3 - 5 working days as in our experience it takes longer than 2 - 3 days Royal Mail say (we dont like to over promise!). Kindest regards, Simon

On 22 Aug 2016 the customer added:
i dont see how the delivery takes longer than 2 to 3 days unless you post it out late your good at always seeing the customer as wrong!! i have a friend who works for royal mail and i can tell you its not often there is massive 4 day delivery on sencond class when ever i order off other companies they use the same delivery method as your self and ive always recieved my item on the second day!! end of the day instead of tring to fob off customers try listening to them to improve your service !!!!

Prices good, service excellent. The products arrived very promptly, well packaged.
I like the fact that it is possible to check details on products on the website, making it easier to know if they are suitable for the animal.
I have bought from the company several times now and I will continue to do so. It is an easy site to use with clear instructions.


I am more than satisfied with the service pet drugs online provide. They have been very efficient and friendly in dealing with each request for products. A trustworthy firm.


Very good Value cheaper than the vets


This is the first time I've ordered from Pet Drugs on Line. Very happy with service and will recommend to friends.
