Why Prescription Flea & Worm Treatments Matter
Parasites are more than a nuisance — they can cause serious illness in dogs and, in some cases, pose a risk to human health. Using effective, prescription flea and worm treatments is one of the simplest ways to protect your dog.
Fleas
Fleas are common year-round and can survive in even the cleanest homes.
They can:
-
Cause intense itching and skin disease
-
Trigger flea allergy dermatitis
-
Transmit tapeworms
-
Lead to anaemia in young or vulnerable dogs
Many over-the-counter products are no longer fully effective and may not break the flea life cycle.
Worms
Dogs can carry worms without obvious signs.
Worms can:
-
Cause vomiting, diarrhoea, weight loss, and poor coat condition
-
In extreme cases can cause blindness
-
Be particularly harmful to puppies and elderly dogs
-
Be passed to humans, especially children
Regular, reliable worming is essential — even for dogs that appear healthy.
Lungworm
Lungworm is increasingly common in the UK. Dogs can become infected by contact with slugs, snails, or contaminated water.
Lungworm can cause:
-
Coughing and breathing problems
-
Bleeding disorders
-
Lethargy or sudden collapse
-
Seizures
-
In severe cases, it can cause death.
Not all flea and worm products protect against lungworm. Specific prescription treatments are required. These can be requested before or at the time of your appointment.
Why Choose Prescription Parasite Treatments?
Veterinary-prescribed parasite treatments offer the highest level of protection for your dog. They are:
-
Clinically proven to be safe and effective
-
Effective against life threatening lungworm
-
Tailored to your dog’s size, age, health status, and lifestyle
-
More reliable than many shop-bought products.
-
Rigorously tested and recommended by your vet due to their efficacy and safety
-
Designed to protect against the parasites that pose the greatest risk
Using non-prescription products can carry risks:
-
Accidental overdose or use of an inappropriate product can cause serious side effects.
-
Some parasites have developed reduced sensitivity or resistance to ingredients used in over-the-counter products
-
If a non-prescription product fails, there is often a waiting period of several weeks before a prescription treatment can be safely given
-
Over-the-counter products are not licensed to use the most effective active ingredients
