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.

Always professional, helpful and friendly. Speedy service and such good value too. Their prices can't be beaten. I always buy from them if I can.
Easy to use website, easy to purchase at a good price and great delivery. Trust is everything with treating our pets. I trust PDO.
Happy with both the product and the prompt delivery just wished the delivery charges weren’t so much!
pet drugs online are very efficient - the food comes the next day and is £10 cheaper for a tray of food than my vets - their website is quick and easy to use -would recommend highly
Excellent communication, speedy arrival, time slot given on day of arrival (although it would be even better if the timeslot was given the day before arrival) and the delivery was prompt. It was easy to change delivery address on day of arrival as I needed to go out.
Product as ordered and delivered on time. Request for feedback every time one makes a purchase is irritating.
Quick and efficient service whether over the telephone or online.
Prices are good and delivery has always been on time.
