Factors To Consider When Buying A Flea And Tick Collar

Before you buy some collars, the claims to be the best flea collar for dogs, take a quick ride through these factors, and then assess the product you are going to buy. This will help you find the best flea collar for dogs that actually works the magic.

1. The Formulation

Many of the dog collars in the market are formulated with chemicals. While this isn’t a problem, it’s better that you go for something environment-friendly. Most dogs are allergic to chemicals and using a random collar on your dog might cause serious skin rashes and even burns.

Thus, before you put on the collar, get it consulted with the vet to see if your dog has an allergic reaction to any of the components mentioned in the formula.

An alternative to the synthetic formula is the all-natural formula that still works wonders. It is made of mostly all-natural oils and extracts that are proven to rid dogs of lice, ticks, and fleas. Such formulas may act slow, but the effect stays on for a long time. Also, most of these formulas have essential oils that are proven to nourish the hair coat. Thus, it provides two benefits. Protection against the flea attacks and also nourishment for the hair coat.

The third category is an amalgamation of the synthetic and natural formula. Such formulas still contain the natural or essential oils that would nourish the haircoat and have the synthetic formula that kills the fleas. Collars with such formulation are considered to be the best ones as it would be suitable for dogs with allergies and would also be environment-friendly. Some leather collars do take care of this.

2. Width Of The Dog Collar

Dog collars come in all sizes. Most common ones come in one-size-fits-all type. When buying a collar, make sure that it doesn’t have much width. Wide-banded collars make it extremely difficult for the dogs to move their neck freely. Also, you still have to use any collar or harness to completely control the dog. In that, the flea collar would restrict the movement and make it miserable for the dog.

3. Size Of The Dog

Make sure that the collar you are buying is designed for the breed and size of your dog. The formulation would be different and also the size. Collars meant for large breed dogs may look inappropriate on small breed dogs and vice versa. The best dog collars take care of this fact and come in many different sizes.

4. Type

You can find two types of pest collars online. One that works on contact and the other that requires the pest to intake the chemicals to see the effect. The best flea collar for dogs would be the contact one that kills all fleas and ticks as soon as they come in contact with the formula.

Another classification of collars includes collars that use chemical pesticides and the ones that use ultrasonic noises to get rid of the fleas. The ultrasonic type is rare as its effects don’t stay for too long. It doesn’t kill the eggs or tamper with the lifecycle of the pests.

On this list of the best flea collars for dogs, we have only mentioned the ones that use chemical pesticides to get rid of the pests.

Keep Your Dog Healthy With The Best Flea Collars for Dogs

Voila, with that we have cracked a well-detailed guide on the best flea collars for dogs that are currently under pest attack. Always make sure that you monitor the actions of your dog once you put on the dog collar. If the dogs are using it for the first time, then you need to be very careful.

If the dogs show any kind of discomfort, it is better that you get rid of the collar as soon as possible to prevent any skin problems.


Q1. What Is The Best Flea Collar For Dogs?

The best flea collar for dogs is the one that contains pesticides in it. Sucha collar slowly transfuses the content all over the haircoat and tampers with the lifecycle of the pests. This way the effect of the collar stays for a longer period and the pests don’t make a re-entry anytime soon.

Q2. Do Flea Collars For Dogs Work?

Flea collars are effective for dogs suffering from irritations and other kinds of skin infections due to the pest attack. Instead of using the ultrasonic ones, go for the pesticide-filled collars that slowly kill the pests and alter the favorable conditions so that the eggs don’t hatch.

Q3. Which Is A Better – Flea Collar Or Drops?

Flea collars are certainly better than drops. Flea collars contain the pesticide which is slowly circulated throughout with the help of the body oils. When it comes to drops, you will have to apply it all by yourself. Also, the flea collar formula is waterproof and its effect is felt as long as the collar is on the dog’s body.
