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
