The 9 Best Flea Treatments For Dogs in the UK

1. Frontline Spot On Flea & Tick Treatment for Dogs – Best Overall

Frontline Spot On is a topical flea and tick treatment and our top choice for best flea treatment for dogs. To use spot-on treatments, you separate the hair at the back of the dog’s neck and then squeeze the contents of the pipette onto the skin. The active ingredient spreads via the animal’s skin and sets to work killing fleas within 24 hours of application. Choose the spot-on treatment that matches the size of your dog and ensure that you follow instructions on how to apply it properly, to get the best results.

Frontline not only starts to kill fleas within 24 hours, but it kills ticks within 48 hours. A single pipette offers protection for up to one month, which means that one pack containing 6 pipettes should be enough to offer 6 months of protection. The pipettes are easy to apply, as long as you can convince your dog to stay still for a minute, but you need to avoid petting your dog for 48 hours after application and it can leave a somewhat sticky residue on the skin that attracts other dogs and cats to lick the application area.

2. Beaphar FIPROtec Spot On Medium Dog 6 Pipettes – Best Value

Beaphar FIPROtec is another spot-on treatment that shares several similarities with the Frontline. It includes 6 pipettes, each offering a month of protection for a total of 6 months’ protection. It uses the same active ingredient, fipronil, which also kills ticks as well as fleas, and it is a spot-on treatment that is applied between the shoulder blades at the back of the dog’s neck.

It can be used on any dog over the age of 8 weeks, but you do need to buy the treatment that is appropriate for your size of dog to ensure that you offer the right level of treatment. It is worth noting that some dogs can react to flea treatments, so you should keep an eye on your dog for 72 hours after application and seek veterinary help if a rash presents. Beaphar’s spot-on treatment is inexpensive and comes with enough for 6 months of treatment, making it the best flea treatment for dogs in the UK for the money.

3. Virbac Indorex Household Spray Dog Flea Treatment – Premium Choice

One of the reasons that fleas are so challenging to overcome is because of the lifecycle of the flea. Fleas lay eggs in bedding, on carpets, and elsewhere around the house, so killing fleas on the dogs themselves only delays reinfection. The most effective flea treatment requires a careful multi-pronged attack and can incorporate a household spray like Virbac Indorex.

Virbac claims that Indorex will kill and prevent egg development for 12 months. It is not for use on your pet but should be sprayed on carpets and flooring, furniture, and even on skirting boards and other surfaces. Use the spray daily for seven days to get full coverage and enjoy full protection. A 500ml can should be enough to treat a full three-bedroomed house but you will need to keep pets out of treated rooms for two hours because permethrin can be toxic to cats.

4. Johnsons Dog Flea & Tick Collar

The Johnsons Dog Flea & Tick Collar is a preventative collar that is worn around the neck and that gives off a flea-killing chemical that kills adult fleas and aims to prevent eggs from hatching. The collar uses a chemical called dimpylate and because this is coated around the plastic collar, it can smell strong at first before fading away and leaving minimal to no chemical on the collar after a few weeks or months. Johnsons claim that the collar works for a minimum of four months.

To use, cut the collar down to size and leave it on for the duration of protection that it affords. You can always place the cut-off sections behind cushions for a little extra protection. The collar is cheap, but its effects do wear off quite quickly, and not all owners enjoy success with this type of anti-flea product. Also, the collar is plastic and can become worn and ugly, quite quickly.

5. ProGroom Natural Oatmeal Dog Shampoo

ProGroom Natural Oatmeal Dog Shampoo combines colloidal oatmeal with a host of vitamins, minerals, and other natural ingredients. It helps to detangle fur and it soothes dry and itchy skin. It is not strictly sold or marketed as a flea treatment, but it does have antifungal and antiparasitic properties, which means that it can kill off fleas and their eggs.

At the very least, this bottle of shampoo will leave your dog looking healthier and it will provide them with a shinier and healthier coat, and it can help combat fleas especially when combined with other anti-flea treatments.

6. Capstar Dog Flea Treatment Tablet

The active chemical, Nitenpyram, is fast-acting and will kill adult fleas within 30 minutes of administering the tablets. A single tablet will work for 24 hours, and once the tablet has taken effect, you can use a spot-on or other treatment to get rid of eggs and to prevent reinfestation. The tablets can be given again after 24 hours, according to how serious the problem is, and the tablet can be given with or without food.

The tablets are fast-acting, with owners reporting that they see the fleas falling off their dog within an hour, but they do only combat live, adult fleas, which means that the eggs and larvae will likely cause reinfestation to occur quickly on your dog.

7. Advantage Spot On Dog Flea Treatment

Advantage Spot On Flea Treatment is another spot-on application. Spot ons are popular because they are easy to apply and the chemicals in the treatment are spread around the dog’s coat without having to spray or wash the dog. Choose the treatment that matches the size of your dog and follow the manufacturer’s instructions to ensure proper coverage.

This packet contains four pipettes, each offering protection for up to a month, which means that a single pack will last for four months. As well as fighting fleas, Advantage Spot On Flea Treatment also helps ward off lice, providing your dog with total comfort and protection.

8. Virbac Effipro Spot On For Large Dogs

Spot-on treatments are applied between the shoulder blades at the back of the dog’s neck. Not only does this position help ensure that the chemical is disseminated efficiently across the dog’s coat but it also prevents the dog from being able to get to the treatment and lick it off. However, you do still need to prevent other dogs and cats in the household from licking at the area.

The treatment can be harmful if ingested, so you will need to keep an eye on all household pets and ensure that kids don’t rub the area, for a minimum of 24 hours after the treatment has been applied. The area may look sticky for a few days afterward, too, but you should avoid cleaning or wiping it away. Effipro is quite expensive compared to some other spot-on treatments but if you have tried several different brands, to no avail, it is worth giving this one a go.

9. Bob Martin Clear Flea Bomb Home Fumigation Kit

The Bob Martin Clear Flea Bomb is a home fumigation kit that is described as fast-acting and effective for household treatment. A single application will kill fleas and prevent reinfestation for up to three months. The flea bomb is relatively easy to use: remove from the box, take off the seal and lid, and ignite the wick.

The flea bomb is considered very dangerous to aquatic life so do not use it in rooms with aquariums or water-dwelling pets. It is advised that you leave the bomb to work for two hours after ignition. To prevent headaches and nausea, you should leave the room vacant and consider opening windows to allow the chemicals to leave the room.

Buyer's Guide: How to Choose the Best Flea Treatment for Dogs

Fleas are small, blood-sucking insects. They live on pets but also reside on cushions, in carpets, and other locations around the home. They are irritating and potentially dangerous to your pets, and they can cause bite marks and rashes on humans, too. If you or a pet suffers from a flea allergy, their presence can be especially dangerous. Generally, dogs with long hair are more likely to suffer infestations, but almost any dog breed can be home to fleas. Read on to your treatment options and to find out which is the best option for your dog and your home.

Types Of Flea Treatment

There are numerous types of flea treatment available, each with its own pros and cons.
