Keeping your four-legged friend flea-free is part and parcel of being a responsible dog owner.

Fleas can cause pets immense distress and can even lead to more serious health problems such as a tapeworm infection if they accidentally eat a flea carrying tapeworm larvae or anaemia. Flea infestations can also cause hair loss, dry inflamed and irritation skin and rashes that may take months to disappear.

But, as pet-owning Mumsnetters will tell you, the right flea and mite treatment for dogs can act as a preventative measure and help to nip infestations in the bud, alleviating your pet’s discomfort and ensuring your home isn’t invaded by any itchy critters.

Fleas can be a problem all year round, but especially during the warmer months, so it’s a good idea to arm yourself with the best flea treatments, recommended by experts as prevention is definitely easier than managing an infestation. 

According to the British Pest Control Association, if you spot fleas on your dog, you should treat them as quickly as possible as fleas can give your dog tapeworm and cause other problems such as flea allergy dermatitis. So, with all the flea treatment options available, which is the right one for your dog? Whether you’re after a tablet, spot on treatment, flea collar, tincture or powder, we’ve done the hard work for you and found the best flea treatment options for dogs, available right now without a prescription.

How we chose our recommendations

Products tried and tested by real dog owners 

We scoured the Mumsnet Forum to find out which dog flea treatments our users rate highly - and which ones they weren’t impressed by. We took note of the active ingredients in the recommended flea products and paid special attention to whether the product was easy to use and apply (as dog’s temperaments differ from each other), as well as how long it took to work and if it offered long-term protection. 

Bestsellers and expert guidance 

We consulted consumer watchdogs and took note of what they looked for in good-quality dog flea treatments and which brands they were recommending to their readers. We also considered advice from the FDA who strongly recommends getting your chosen flea product vetted by your veterinarian, especially if your pet has any health conditions. You should also carefully read the label, the package insert, and any accompanying literature to make sure you’re using the product correctly and in the right dosage. 

Trustworthy consumer reviews  

Finally, we collated all that information and then looked at other online reviews to see which dog flea treatments had received the best recommendations from consumers across the board, looking out for any criticisms or disadvantages you may want to consider (such as whether the product could cause skin irritations or hair loss, to come up with our final list of best flea treatment products, available right now.

Here are the best flea and tick treatments for dogs in 2022.

What is the best dog flea treatment? 

The most effective flea treatment for dogs is the Indorex Flea Spray. Highly recommended by pet-owning Mumsnetters, this spray kills all adult fleas and dust mites in the home and prevents the development of eggs and larvae for up to 12 months. Just remember it’s a home treatment and not suitable for your dog’s skin. 

How do I know if my dog has fleas?

Usually the signs of a flea infestation are pretty easy to spot. If your dog is constantly scratching, biting their skin (causing hair loss) and the skin itself is red, scabby and irritated, then this all points to fleas.

If you suspect your dog has fleas, you should inspect their skin by parting their fur with your fingers. If you spot tiny dark insects, smaller than ants, which jump or scurry away quickly, these are fleas. Flea excrement looks like finely ground black pepper, so even if you don’t see any fleas themselves, this dirt is evidence that fleas are living on your dog.

Fleas usually favour dogs’ armpits and groin area, so be sure to check these hotspots first.

What do vets recommend for fleas?

The Royal Veterinary College recommends using a spot-on flea treatment which is applied to the back of the neck on a monthly basis. Alternatively, your vet can prescribe tablets that control and kill fleas if other treatments fail.

How do I choose the right dog flea treatment? 

There are a number of different types of dog flea treatment available on the market which do not require a vet’s prescription:

  • Monthly spot-on treatments
  • Oral treatments such as tinctures, powders and tablets 
  • Medicated shampoo
  • Collars
  • Treatments for the home

It’s worth noting that no two dog flea products are the same. When you’re choosing a flea treatment, you should consider the following:

  • Whether you need a treatment for small, medium, large or extra large dog
  • Whether the treatment is suitable for the breed
  • If you’re buying a flea treatment for a puppy, is your dog old enough for the treatment?
  • Are you looking for a one off or ongoing treatment?
  • Can the  product be used alongside other flea treatments?
  • How quickly the product gets to work
  • The active ingredient it contains
  • If your dog has sensitive skin, will the flea treatment irritate it further? 
  • Does your dog have an active infestation? This will determine the type and strength of the treatment. 

What’s the difference between over-the-counter and prescribed flea treatments? 

According to experts at Preventive Vet, some flea and tick treatments such as sprays, collars and spot on treatments like FRONTLINE are considered to be safe enough to be sold over the counter as they aren’t absorbed into your pet’s body the same way a prescription medication is, hence, no prescription is required. While some flea treatments on our list have a veterinary stamp of approval, none need an additional prescription. 

On the other hand some tick and flea treatments need closer regulation as some active ingredients need to be carefully administered in the right quantities, and are therefore only dispensed by medical professionals. In some instances, your dog may also need to be checked before going onto a flea treatment programme, in which case, a treatment protocol (as well as the type of treatment) will be discussed beforehand.
