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
