Buy now

Why we chose it

Our pick for the best overall flea treatment for dogs is Sentinel Spectrum. It has a rating of 4.7 out of 5 stars on Pet Circle.

Sentinel Spectrum is a chewable flea treatment for dogs of all sizes. It helps protect against heartworm while controlling fleas by stopping them from breeding. The brand also claims it treats and manages all major intestinal worms and tapeworms when given regularly. It should be given every month, preferably on the same date.

Customers praised the product's efficacy, versatility and taste. Most buyers said their dogs eat the chews like their favourite treat, making treatment a lot easier than more traditional options. While it's on the expensive side, most customers said it is worth it as it helps control and treat various issues, like heartworm and fleas. A few others had difficulty administering the chews, but this seems to be an isolated issue.

Tropiclean Natural Flea and Tick Spray

Best natural flea treatment for dogs

• Easy to use

Cons

• Not everyone is a fan of its scent
• Reviewers said the sprayer doesn’t evenly coat their dogs’ fur

Buy now

Why we chose it

For the best natural option, we recommend the Tropiclean Natural Flea and Tick Spray. On Amazon, it has a rating of 4.2 out of 5 stars from over 2,000 reviews.

Tropiclean's Flea and Tick Spray contains EPA-approved natural essential oils like clove oil, lemongrass and cinnamon oil. It also doesn't contain pyrethrin or permethrin. The blend helps kill up to 99% of fleas, ticks, larvae and eggs. It is also suitable for dogs and puppies 12 weeks old or older.

The general sentiment is that this is an effective natural flea treatment that repels fleas and ticks. Customers said 2-5 sprays are more than enough to coat their medium-sized furry friend with the treatment. However, larger dogs may need more sprays for better protection. It has a pleasant citrus scent, but some buyers found it overpowering.

NexGard Spectra

Best flea tablets for dogs

• Easy to administer

Cons

• Expensive
• Not suitable for younger puppies

Buy now

Why we chose it

NexGard Spectra is our choice for the best flea tablets for dogs. It has an average rating of 4.8 out of 5 stars on Amazon and on Pet Circle.

NexGard Spectra is enriched with insecticides and acaricides to kill fleas and other parasites before egg production. It also helps control flea allergy dermatitis and prevent issues due to intestinal worms. This chewable treatment is easy to use, providing your dogs with ongoing protection against adult parasites, including those that can infect humans.

Thousands of customers were impressed by the product's performance, versatility and ease of use. Because it's a monthly flea tablet with a tasty flavour, dogs tend to gobble it up just like any delicious treat. The tablets are quite expensive, but most buyers said their efficiency is well worth it.

Cons

• Some customers said it leaves their dogs’ fur dry and matted
• Doesn’t control paralysis ticks

Why we chose it

With a rating of 4.0 out of 5 stars on Pet Circle, we picked Fido's Flea Shampoo as the best flea shampoo for dogs available online.

Fido's Flea Shampoo contains natural insecticide and pyrethrin to control lice and fleas on dogs and cats. However, it is not suitable for controlling paralysis ticks. Its mild, soap-free formula won't irritate sensitive skin, leaving your dogs' fur shiny and soft. This shampoo is also available in 250ml and 1L options.

According to customers, this flea shampoo produces a rich lather that evenly coats their dogs' skin and fur. It effectively controls fleas while leaving the fur healthy-looking and soft. It also rinses cleanly without residue at all. A few customers said it dried out their dogs' fur, but this seems to be an isolated case.

Seresto

Best flea collar for dogs

• Effective for up to 8 months

Cons

• Tick control is only effective for up to 4 months
• Expensive for just a single-collar pack

Buy now

Why we chose it

If you're looking for the best flea collar for your dog, we recommend Seresto, which has a rating of 4.7 out of 5 stars on Amazon.

Seresto is a flea and tick collar that repels and kills ticks and fleas through simple contact. The collar works by releasing active ingredients in low doses, offering up to 8 months of flea protection and up to 4 months of tick control. According to the brand, because of its minimised contact, ticks and fleas won't have a chance of biting your dog. This then reduces the chance of irritation, tick paralysis and blood loss.

Customers praised the product's performance and ease of use. It is odourless and water-resistant, ensuring that your dogs are well protected against fleas and ticks without causing any irritation. Several reviewers also said it is non-greasy, which makes administration a lot simpler. Apart from reducing the transmission of tick-borne disease, it helps kill paralysis ticks.

Today's Seresto deals

• Safe to use for puppies 8 weeks old or older, weighing at least 2kg

Cons

• Only up to 12 weeks of protection against brown ticks
• Not cheap

Why we chose it

BRAVECTO Spot On is our pick for the best flea and tick treatment for dogs. It has a rating of 4.5 out of 5 stars on Pet Circle.

BRAVECTO Spot On is a topical flea and tick treatment that treats and prevents flea and paralysis ticks for up to 6 months. It also helps control brown dog ticks and flea allergy dermatitis. Additionally, it is suitable for controlling sarcoptic mange and flea tapeworm. It is also safe to use for puppies over 8 weeks of age, weighing at least 2kg.

According to reviews, this topical treatment is easy to use and provides lasting tick and flea control for their dogs. A pack costs over $70, but most buyers said it is worth the hefty price tag given its efficacy and versatility. One customer said it doesn't have any visible side effects, while others added that it's the ideal option for picky-eating dogs who don't like chews. It only offers up to 12 weeks of brown tick control, but this doesn't really bother most customers.

• Affordable

Cons

• Requires monthly application

Why we chose it

For controlling fleas and worms, we chose the Advocate Flea, Heartworm and Worm Control as the best treatment option. It has a rating of 4.9 out of 5 from over a hundred Pet Circle reviews.

This flea and worm treatment contains fast-acting ingredients that kill various parasites, including fleas, heartworm, intestinal worms, lice and ear mites. Each pack comes with 6 tubes (1ml each) for monthly application. It has a water-resistant formula that kills fleas and ticks within 3-5 minutes of contact.

The general sentiment is that this is an affordable all-around flea and tick treatment suitable for dogs and puppies. The 1ml tubes are easy to administer without leaving a greasy film on dogs' skin and fur. But compared to other topical treatments for dogs that offer up to 8 months of protection, the monthly application may be tedious for some customers.

Today's Advocate Flea, Heartworm and Worm Control deals

• Suitable for puppies and kittens

Cons

• One pack only contains 3 individual 0.25ml tubes
• Leaves a greasy film according to customers

Our team recommends Revolution Flea Treatment Drop as the best flea treatment for puppies available online. It has a rating of 4.3 out of 5 stars on Amazon

The Revolution Flea Treatment Drop is a monthly topical treatment for controlling and preventing heartworm, roundworm, tapeworm and hookworm. It also manages lice, ear mites and sarcoptic mange in puppies. It has a spreadable formula that becomes waterproof after 2 hours. Each box contains 3 tubes of 0.25ml that must be applied once a month for continuous protection. It is also suitable for puppies and kittens aged 6 weeks and older.

Customers praised the product's easy application, efficacy and versatility. Apart from fleas, it helps kill and control different parasites, ensuring your pups are protected and healthy. It doesn't have any odour but leaves a sticky film on the skin. However, customers said this goes away after a couple of hours.

Frequently Asked Questions

How often should you use flea treatment on a dog?

It is best to use flea treatment on a dog every 4 weeks all year round to avoid infection.

Is oral flea treatment for dogs better than topical?

Both are safe and effective in protecting your beloved pet from fleas.

Topical flea treatments do not pass through the skin barrier and are absorbed into the bloodstream. They are best suited for dogs with a history of reactions and who do not tolerate oral flea treatments. However, this flea treatment typically leaves a residue and can be washed off during baths.

Oral flea treatments do not leave any messy residue. You also don't have to worry about the solution being washed away during baths. However, some owners might have difficulty giving oral flea treatment to their dogs.

What possible side effects can a flea treatment for dogs cause?

Some flea treatments can cause skin irritation, diarrhea and vomiting. Consult your vet to find the best type of flea treatment based on your dog's age, health and sensitivity.

How do you know if my dog is allergic to a flea treatment?

To determine if your pet is allergic to a certain flea treatment, look for the following symptoms:

• Runny nose
• Hair loss

• Watery eyes
• Itchy skin and rashes
• Difficulty breathing
