Features to Consider When Buying Flea Collar for Dogs

Dogs can’t express their opinions about something, so you’ll want to pay extra attention when buying something that concerns them. A collar that’ll stay around your dog’s neck for 8–10 months should cover some essential features. Check them out here.


Any good flea collar for dogs should be waterproof. It’ll save you the hassle of continually monitoring your dog to make sure he doesn’t get it wet. We all know dogs love water activities, whether it’s bathing, swimming, or playing under the rain.

Buying a waterproof collar will also ensure that the dog stays protected all the time. That way, you don’t have to be around him during his playing time.

Long-lasting Effect

Some dogs take a lot of time to get used to a new collar. So, replacing it frequently will be a hassle you’re in no need of. The shortest road is to get a collar with a long-lasting effect, ranging from eight to 10 months. Of course, the longer, the better.

Collars with shorter spans will be more affordable, which is why a lot of people get tricked into buying them. However, replacing the collar every few months, even if it’s affordable, isn’t cost-efficient. You’ll find yourself paying the same amount again and again.

Safe Ingredients

Although collars with synthetic insecticides may be more efficient, sticking to natural ingredients is the better option for your dog’s safety. All pesticides are toxic on some levels. Even if the collar is labelled safe, it’s definitely not completely safe, even if it’s not too harmful.

If you’re getting a collar infested with insecticides, make sure you’re buying from a trusted source. Illegitimate companies may include toxic materials without disclosing them.

You’ll want to check the toxicity level of the collar if it contains any of these materials:

  • Propoxur
  • Lufenuron
  • Permethrin
  • Tetrachlorvinphos

Right Size

Buying a collar in the right size for your dog seems easy, but it’s not. You’ll want the collar to be tight enough to release the ingredients but loose enough to pass over your dog’s head. We see dogs wearing wrong-sized collars all the time, and it’s mostly because their owners forget to measure their necks before buying. 

The best thing to do is to take your dog’s measurement before buying. Additionally, you should check the manufacturer’s size chart and abide by it. You’ll hopefully end up with the right size.

Even better, you can get a one-size collar that fits all dogs, like the options in our list below. It’ll save you the hassle of checking size charts.

Pleasant Scent or Odorless

The last thing you want is irritating your dog with a strongly scented collar, especially when he’s already not a big fan of the collar. A lot of collars on the market have scents too strong for dogs. When choosing the one for your pup, make sure to get one with a subtle, pleasant smell.

Alternatively, you can ditch the scented idea and get an odourless collar. That’s the better choice if your dog gets easily irritated at scents.

Flea Collars for Dogs Reviews

Here’s a roundup of the best flea collars for dogs on the market. We picked these options in terms of efficiency, durability, and safety. No matter which one you choose, you can be sure you’re getting a reliable product.

WOLFWILL Flea and Tick Collar for Dogs


  • 10 months of efficiency

The Wolfwill collar is one of the longest lasting collars on the market, staying effective for ten months. It doesn’t only repel fleas, but it also protects your dog from ticks, lice, and pests. On top of that, it’s waterproof, so your dog can play around all he wants while wearing it.

The collar measures 26 inches, and it’s fully adjustable to fit all dog sizes. For smaller dogs, you’d have to adjust its length, buckle it, and cut the rest off. You can leave 2–3 extra inches for adjusting, though.

If your dog gets easily allergic, you’ll love the fact that the Wolfwill collar is hypoallergenic. It’s eco friendly too, so it’s safe for both your dog and the environment.


Toldi Flea Treatment for Dogs

The Toldi collar keeps spreading the formula on your dog’s body for eight months. It costs more than all the options on this list, so we’d have liked a longer lasting efficiency. It’s still pretty sufficient, nevertheless.

The collar comes in one size that fits all dogs. It’s 25 inches long, and it’s fully adjustable. Not to mention that it comes in an attractive purple colour that’ll keep your dog trendy among his pals!

Moving on to the material, the collar is made of a top-notch plasticizer that’s flexible and durable. It’s not brittle, so it won’t irritate your dog.

  • Waterproof
  • 8 months of efficiency
  • 25 inches long universal fit

The Fenvella Flea and Tick Collar is another great option that will keep your dog protected for up to 8 months.

This collar is allergy free, and includes 100% healthy ingredients with six kinds of natural healthy formulas.

The waterproof design means that you don’t have to worry about your dog taking a bath or going for a swim, and the collar fits most dogs as it is a univeral fit with a super long, flexible strap.


Vienapoli Natural Flea Treatment for Dogs


  • 100% natural and hypoallergenic
  • Waterproof
  • Produces a soothing lemon smell

When it comes to efficiency, the Vienapoli flea collar is hard to match. It’s designed to slowly release the active ingredients on the dog’s skin throughout a period of 24 hours. Therefore, it ensures staying efficient for the longest time possible.

The collar is 100% natural, so you can rest assured your dog won’t be exposed to synthetic ingredients. Additionally, its formula is hypoallergenic, so it’s safe for allergic dogs. The ingredients include citronella, lemon, clove, peppermint, and eucalyptus. Combined, they leave a nice soothing smell on your dog’s coat.

The collar comes with a robust buckle that doesn’t come off during activities. Once you plug it and cut the excess off, you can be assured it won’t come off your dog.



A good quality flea collar can help to keep your healthy, and as the best collars offer 8-10 months of efficiency it is an inexpensive purchase that can offer significant benefits.

All of the collars we have reviewed will do an excellent job, although our favourite is the WOLFWILL Flea and Tick Collar. 

At ten months of efficiency, it’s one of the longest lasting collars on the market. Plus, its formula is hypoallergenic, and it’s waterproof.
