To make sure you get the best from your plan it's important you use the correct dosage which is based on your pet’s weight. If you're buying the ManyPets Flea, tick and worm plan for the first time, you'll get a chance to tell us your pet's weight before you purchase.
If you're already a customer and need to update your pet's weight, you can do this in the My Plans area of our website.
It's also important you follow the application instructions carefully. Remember you should never share treatments between pets.
