Fleas are more than just an itchy nuisance - they can cause serious health issues for your dog and invade your home. This guide explains how to get rid of fleas on dogs and how to prevent future infestations.

Key Takeaways

  • Spot the signs: Look for excessive scratching, flea dirt, and irritated skin.

  • Treat both pet and home: Fleas spend 95% of their life cycle in the environment, not on your dog.

  • Consistent prevention: Regular flea treatments and home hygiene stop infestations before they start.

  • Act early: Fleas reproduce fast; early detection saves time, money, and discomfort for your dog.

How Do I Know If My Dog Has Fleas?

Fleas are tiny, but their effects are obvious if you know what to look for.

Dogs with fleas often:

  • Scratch or bite at their coat more than usual.

  • Groom excessively, particularly around the neck, hind legs, and base of the tail.

  • Have small black specks in their fur (flea dirt) or notice scabs and red lesions on their skin.

  • Show signs of restlessness, pacing, or agitation.

Other signs your house has fleas:

  • If your dog starts avoiding carpeted rooms they previously visited, it’s possible they have been bitten by carpet fleas.

  • You may even spot fleas on bedding, carpets, or furniture.

  • Keep an eye out for bites on yourself or other family members too - fleas don’t live on humans but can still cause discomfort.

The Dangers of Fleas on Dogs

Fleas are more than just irritating - they can cause serious health issues.

  • Skin allergies: Flea bites may trigger Flea Allergy Dermatitis (FAD), causing inflamed, itchy skin.

  • Tapeworms: Fleas can carry tapeworms, which infect dogs if accidentally swallowed. If your pet does contract tapeworm, as well as treating the worms, you will also need to manage the flea problem at hand, otherwise your pet will quickly become reinfected.

  • Blood loss: Severe infestations, especially in puppies or older dogs, can lead to anaemia.

Because of these risks, early detection and treatment are essential to protect your dog’s health.

How to Get Rid of Fleas

Fleas spend most of their life cycle in your home, not on your dog. Roughly 95% of the flea life cycle is spent as eggs, larvae, and pupae found in carpets, bedding, and furniture.

A successful flea strategy involves treating both your pet and your home.

1. Spot-on Treatments

Spot-on flea treatments are applied directly to your dog’s skin, usually between the shoulder blades. They are fast-acting and help protect both your pet and your home from infestation.

  • Kills fleas, ticks, and biting lice, depending on the formula

  • Some contain insect growth regulators (e.g. (S)-methoprene) which prevent flea eggs from hatching, breaking the life cycle - VioVet vet, Dr Nicholas Garside BVetMed MRCVS, states.

  • Easy to apply compared with oral tablets - ideal for fussy or nervous dogs

  • Dose as often as the product datasheet advises for ongoing protection. This is usually every 1 or 3 months

Our spot-on flea products offer the same trusted active ingredients as top brands for less, quickly and effectively killing fleas, ticks and biting lice.

2. Collars

Flea collars offer long-lasting protection, up to 7–8 months depending on the product, in a single application - making them a convenient alternative to monthly treatments.

  • They work by slowly releasing low doses of active ingredients through your dog’s skin and coat to repel ticks and/or kill fleas.

  • Many collars feature repellent action, so ticks don’t need to bite to be affected.

  • Once fitted, the collar should be worn continuously and checked regularly - especially for growing puppies, as the fit may need adjusting over time.

3. Oral Tablets

Oral flea treatments work systemically, killing fleas when they bite your dog.

  • Suitable for dogs who don’t tolerate topical applications

  • Quick-acting and easy to dose according to weight and size

4. Treat your home

A clean home is key to breaking the flea life cycle. "About 95% of the flea’s life cycle is found as eggs, larvae, and pupae in carpets, bedding, and furniture - not on your dog".

  • Vacuum carpets, rugs, and furniture thoroughly.

  • Hot wash pet bedding at 60°C (where possible).

  • Use household flea sprays like Indorex Defence or Dechra RIP Fleas.

Repeat home treatments every three weeks to target newly hatched fleas from pupae.

Extra tips:

  • Use flea treatments for all pets, even those not showing symptoms.

  • Apply flea treatment according to product instructions without skipping doses.

  • Follow instructions carefully: do not bathe or swim your dog for 48 hours after application of spot ons, and repeat treatments as recommended.

  • Flea infestations can take 2–3 months to fully clear. Stick with your treatment schedule, and don’t be alarmed if fleas reappear temporarily - it’s normal as eggs continue to hatch.

How to Prevent Fleas on Dogs

Prevention is always easier than treating a full-blown infestation. You can reduce the risk of fleas by:

  • Checking your dog regularly: Use a flea comb to inspect the coat and skin.

  • Using preventive treatments: Topical applications, collars, or appropriate oral medications.

  • Maintaining a clean home and garden: Regularly vacuum, wash bedding, and keep your garden free from debris.

  • Speak to your vet: For advice on the best preventative treatments, both for your home and your pet, and make sure you're clear on how regularly you need to repeat them.

Dog Flea FAQs

How often do you flea a dog?

Fleas are persistent year-round. To protect your dog, apply flea treatment according to product instructions without skipping doses. Be especially diligent for dogs that go off-lead, visit other pets, or live in multi-animal households.

Can a human get dog fleas?

Fleas can bite humans but cannot live on us; they need a furry host.

How long can fleas live without a host dog?

Adult fleas can survive for several days without a host, but most of their life cycle occurs in the environment. The eggs and pupae can survive without a host for months by laying dormant in the environment.

How do dogs get fleas?

Dogs can pick up fleas from other animals, wildlife, or even the environment when out on walks or play dates. Fleas can also hitch a ride into your home on clothing or shoes, and once inside, they quickly spread.

Are cat and dog fleas the same?

They are very similar, and both can infest either species, though they prefer their primary host.

How long after flea treatment can I bathe my dog?

Most spot on treatments require a 48-hour window before bathing to ensure effectiveness. Oral treatments usually do not require a wait before washing is permitted. Bathing may reduce the length of time that collar treatments work. It’s important to follow the manufacturer’s guidance on when to bathe and the frequency of bathing, as found in the product datasheet.
