Parasite Control

At Crieff Vets we stock a wide range of worm, flea and tick products. It can sometimes be confusing and difficult to find the correct product(s) for your pet given the large number of product choices, routes of administration and combinations of parasites treated. Therefore, one of our team will be happy to advise you to ensure you get the most suitable product for your pet.


Puppies and kittens are infected with roundworms from their mother and should be wormed several times at fortnightly intervals. Adult dogs & cats should be wormed every 3-4 months on a public health basis to reduce roundworm infection of children. Dogs that scavenge may need to be wormed more often for tapeworm. Outdoor adult cats usually need to be wormed every 3 to 6 months for tapeworm, depending how much they hunt. Occasionally very successful hunters might need treatments at shorter intervals.


Wormers are available as powder, liquid, tablets and spot-on preparations. The right choice depends on the age of the animal, round or tapeworm control and ease of administration.


Lungworm is known to be an increasing problem in the UK. Animals are infected by contact with slugs and snails. Lungworm can cause respiratory problems and bleeding disorders which can be difficult to diagnose and treat. Control programmes for round and tape worms often do not control lungworm and specific products are required.


There are a number of different products available to prevent fleas. There are a number of different spot-on products which provide 4 weeks protection or a tablet for dogs which provides 3 months protection. These products kill all fleas on the animal within 48 hours of administration. Some products also treat worms, lungworms and mites or protect against ticks.


If an animal is already infested with fleas then they should be treated with one of the above products but it may also be necessary to treat their environment. The majority of fleas live in the environment and can then re-infect the animal, so regular vacuuming and insecticidal sprays for the house will also be required to control a flea outbreak.


Ticks are a significant problem in our area. Although still relatively rare, there is an increasing awareness and risk of tick-borne disease in the UK. It is, therefore, important to prevent the tick biting the animal in the first place rather than just removing them once they are attached and feeding.


Ticks can be prevented on dogs using products that either repel them to prevent attachment or kill the ticks  very soon after they have attached and before there is any chance of spreading infection. These products include spot-ons, tablets and collars.    


As some insecticides used in the dog products can be toxic to cats, the choices for prevention in cats is slightly more limited. The spot on products for cats therefore do not repel ticks but will kill them within 48 hours of attaching. There is a collar available which does repel ticks and prevent attachment but some cats will not tolerate, or lose, collars.
