We send out products according to the recommendations of the manufacturer and the World Small Animal Veterinary Association.
Our tails.com subscription protect against fleas, ticks and worms: the products we use kills fleas for 8 weeks, ticks for 4 weeks and wormer that only needs to be administered every 3 months in adult pets.
This means flea/tick spot-on will arrive every month and wormer every third.
There are many other factors and variations that our veterinary team takes into account when determining the schedule and during very high flea season the vets may decide to use slightly stronger spot-on medications.
