What are flea collars for dogs and what advantages do they have?

A flea collar for dogs is a product that protects your pet against parasites such as fleas, ticks, or others. It is a piece of plastic or rubber, that can be adjusted, and that contains a chemical repellent. The collar releases the chemicals, which expand and create a protective barrier for your dog.

Here are some advantages of flea collars:

  • They allow the dog to move freely, even in water. The vast majority of collars are waterproof and resistant to any moisture.
  • They last for a long time, usually up to 8 months.
  • Many collars also act as a mosquito repellent, as well as as repellents of mosquitoes belonging to the genus phlebotomies, a transmitter of leishmaniasis.
  • They are affordable.
  • They give you peace of mind, knowing that your pet is safe.
  • They have no order, or sometimes a pleasant oder.

How do flea collars for dogs work?

The main function of flea collars is to expel a chemical that repels parasites and is stored in each collar. The substance is released in low concentrations and distributed all over the dog from head to tail. All you have to do is put the collar on your pet.

The collar is usually one size, and will fit your dog no matter how big or small. It has to be loose enough to fit two fingers between the dogs neck and the collar, so that the dog is comfortable and does not notice the collar. Once you have placed the collar on your dog, it will do the rest!

What types of flea collars are there?

The main differentiation when it comes to flea collars for dogs is whether it is a chemical flea collar or a natural flea collar. This will depend on the ingredients in the collar and it is recommended that it be as natural as possible. The following differentiation will be based on the type of parasite they fight.

There are flea collars that only fight fleas and other more complete ones, which also act against ticks or mosquitoes. Experts recommend being careful when choosing a collar because the chemicals they contain must be suitable for the parasite you want to repel. Ideally, you want to choose a recognized brand because there will be more quality assurance.

How long do flea collars last?

The duration of effectiveness of flea collars for dogs depends on the model and brand. It is longer than other anti-parasitic drugs, such as pills (which we will explain later). You have to read the instructions carefully before buying the collar, but generally they can last up to eight months before their expiration date.

As a general rule, it is recommended that, depending on the time indicated by the manufacturer, the collar is changed at least twice a year. Be careful, because there are collars that can have different protection for each type of parasite. For example: four months against fleas, but six against ticks. Keep in mind what your dog needs!

From what age can my dog use a flea collar?

A veterinarian can always give us the best recommendations regarding age to start using flea collars, but also the collars themselves will have their own indications. There are brands that warn that puppies under six or even eight weeks do not use flea collars. Nor very small breeds with delicate immune systems.

The main reason for this is that the dog can tear off the collar or bite it while playing and suffer some type of poisoning with the chemicals it carries. Puppies under eight weeks have an immature immune system and are not yet able to fight the toxins of these products. Therefore, it is better to avoid possible risks.

What is the best way to use a flea collar for dogs?

In addition to the recommendation regarding the age of the dog, we have other tips, such as:

  • Keep the flea collar out of reach of children, food, and eyes.
  • Wash your hands after handling the collar.
  • Ensure that the dog cannot bite the collar.
  • If you have several, store the product in a cool and dry place.
  • If there is a severe parasite infestation, the collar should be replaced more often than indicated on the packaging.
  • For a better result, it is recommended to bathe the dog before placing the collar  on.
  • Check for allergic reactions, especially during the first few hours of use.

Do flea collars have the same effect as pills and medicine droppers?

The two products, flea collars and medicine droppers, are anti-parasitic, but there are differences between them. Medicine droppers and pills are effective in attacking parasites that are already present, while collars are more preventative. On the other hand, the durability is greater in the case of collars than in medicine droppers.

Pills have a higher price and, in addition, a series of subsequent recommendations must be followed. For example, the dog cannot be bathed during the two days following the application. It is best to study each case and even consult the veterinarian, who will help you choose the most appropriate method. The collar is undoubtedly the simplest, practical and economical option.

Shopping Criteria

Now we will go over the main criteria that you should pay attention to before buying the best flea collar for your dog. Among them are the composition of the product and duration of its effect, since they are the key factors. The collars must also be changed as often as recommended, or they will stop working.

Repellent Composition

The ingredients of the repellent in dog flea collars is very important. Some dogs have some intolerance to the most common substances against pests and it is advisable to go with natural and zero toxic products. There are brands that are increasingly focused on this, and have 100% natural ingredients. Look for this!

Effectiveness Time

As we have mentioned, the effectiveness time depends on each collar and each brand. This is due to the active ingredients and the amount of chemicals on the animal's fur. Try to find the greatest possible effectiveness and keep in mind in the collars that protect against several insects that the protection is not the same in all cases.

Collar Dimensions

Most of the collars on the market conform to the same measurements and all you have to do is cut the collar once it is adjusted. If your dog is very large, there are flea collars specially designed for them that are longer. The size of each collar will be specified on the packaging.
