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.

Web page excellent, prescription food was half the price that my vet prescribed for my cat and quick delivery. Thank you, I will definitely recommend you.
I was sent a text and email saying my order was out for delivery and would be delivered later that day. I was at work and my neighbour said they would take the delivery. My neighbour waited in all day, but nothing arrived.
I received another text and email saying the same thing the following day. I called pet drugs online to confirm delivery was happening and explained situation. I received no apology and was told it was due to “cyber monday” meaning some orders didn’t leave the depot.
This is the second time my order from pet drugs online has been delivered on a different day, after a text and email saying it was out for delivery and would be delivered that day.
My order did arrive, however I will not be ordering from pet drugs online again
