To keep your pet fully protected, annual vaccination is required. However, your pet’s risk profile is assessed with the aim to give protection with as few vaccinations as possible. Which is the best wormer and flea product for my pet? There is no simple answer. There are wormer/ flea products which treat both worms and fleas in one simple drop on the back of the neck, pills taken by mouth or as a treat, and long-acting flea prevention injections which last 6 months. Ask the vet or member of staff for advice. Please remember for some products we do need to see your pet prior to dispensing.
