Flea treatment (dog, 3 months)
Typical UK price: £18–£50
What is flea treatment (dog, 3 months)?
Prescription flea treatments for dogs kill adult fleas and disrupt the flea life cycle. Options include monthly spot-on solutions, long-acting oral tablets (Bravecto lasts 3 months), and combination products that also treat ticks and worms. Regular treatment is recommended year-round, as flea populations survive indoors throughout the winter. Dogs can also pass fleas to other household pets.
Why do prices vary between vets?
- Dog weight — flea products are weight-banded, and larger dogs require larger doses at higher cost
- Product choice — long-acting oral treatments cost more upfront but less per month than monthly spot-ons
- Whether purchased from the vet or via a written prescription — online pharmacies can offer savings of 30–50%
- Combination products — treatments covering fleas, ticks, and worms cost more than standalone flea products
Frequently asked questions
What is the difference between spot-on and oral flea treatments for dogs?
Spot-on treatments are applied to the back of the neck and absorbed through the skin. Oral tablets (such as Bravecto or NexGard) are given as a chew or tablet and work systemically. Oral products are not affected by bathing and some last longer per dose. Your vet can advise on the best option for your dog's lifestyle.
Can dogs get fleas in winter?
Yes — central heating keeps homes warm enough for fleas to survive and breed year-round. Flea pupae can lie dormant for months and hatch when conditions are favourable. Year-round treatment is the only reliable way to prevent infestation.
Can I use dog flea treatment on my cat?
Never use dog flea treatments on cats without explicit veterinary guidance. Many products, including those containing permethrin, are highly toxic to cats and can be fatal. Always use species-specific products.
