But still, many are the dog experts who are against it, considering it violence against the animal. It is common among hunters to make dogs follow their rules.

Why should you buy a dog collar that incorporates GPS?

Dog collars that integrate geolocation technology have become very fashionable. Normally, it has always been more common to integrate the GPS into collars made to train the dog, since it is left untied, but lately there are more collars that can carry it.

Purchase criteria

When you have to buy a collar for your dog you must remember that there is a great variety, depending on what you need. You should also take into account the comfort of your pet. In this section we make a selection with the most important aspects that you should observe when you go to buy one of these products for your cute dog. These criteria are:

  • Closing
  • Features
  • materials
  • Size
  • Weight
  • Ingredients and allergies for deworming collar
  • Additional features


There are different ways that you can close a collar for your dog. When choosing a closure, take into account the personality of your pet: if it is more relaxed or less patient, for example. The important thing is that the collar is simple to put on to cause the least possible discomfort to your pet and you during the process. The most common closures are:

  • Plastic click closure: It is quick to close and open for you. And at the same time it is difficult for your pet to let go of it. You just have to be careful that, when closing, you do not pick the animal’s hair or even pinch the skin because it can be painful.
  • Buckle: It is more tedious to put on, but it is difficult for the dog to open it. Its size is easily adjustable.
  • Velcro: It is inconvenient because it can come loose more easily. But there are those that turn inside a ring to be more secure. Easy to put on.
  • Clasp: Quick to put on, although your dog could remove it more easily than other methods.


As we have seen previously and in a detailed way, there are various functions that necklaces can carry out. You just have to choose the style of collar, according to the needs of your dog or you. According to this, you can find products especially to cover these functions:

  • To deworm or avoid pests
  • To attach to a walking leash
  • To train
  • To prevent him from barking unnecessarily
  • To adorn your neck
  • To cool your pet in summer


The material of a dog collar can make it more or less comfortable for your pet. The most important thing is that it is resistant and of a light material. They can also include materials with complementary functions such as making your dog visible at night. The most common types of necklaces that you can find according to their material are:

  • Nylon: A very common material for walking collars, for those that help prevent your dog from barking or for training collars. It is very resistant, soft and easy to clean. One problem is that in short-haired dogs it can cause friction that can become sores. Don’t leave it on for twenty-four hours.
  • Reflective nylon: Similar features to the previous one, but visible for night walks.
  • Iron: Most common for large, difficult-to-train dogs. It is a heavy material and it is not comfortable for the animal. Sometimes it incorporates spikes as a punishment training method.
  • Leather: Very used, light and of good quality. They last longer. They are recommended for all breeds. They are usually with a buckle closure.
  • Plastic: more common for deworming collars, since these have to be worn 24 hours a day. They do not weigh. They should not be pulled because they can damage the animal’s skin.
  • Fabric: This material is more common for necklaces, as it is not resistant to pulls of any kind.


The size of a necklace is very important for it to fulfill its function. It cannot be very small, because it could cause serious respiratory problems for your pet, with the consequences that this entails. On the other hand, it should not be too large, since the animal could easily remove it from its neck and the accessory would cease to fulfill its function.

Also, with the mania that many dogs have for chewing objects, you could destroy it with your teeth to play with it. This would make you have to spend money on a new necklace. And also, if it is deworming and has an ingredient that can be toxic for oral consumption, it could lead to other health problems. There should be two fingers between the animal and its collar.


It is important that a collar does not feel heavy on your pet because it could cause pain in the cervical area. The necklace must be light. And with a weight adapted to the size of your dog and its strength. There are very heavy training collars, as is the case with those made with iron, but these should not be worn more than the hours in which you use it for that function.

Ingredients and allergies for deworming collar

It is common for products created to prevent or eliminate parasites to contain natural ingredients. On the planet we can find a huge number of plants that many parasites hate and avoid. The most common are geraniol, citronella, lemon, lavender, eucalyptus or cedar. They are always for external pests of the animal.

Some of the ingredients, such as the aforementioned geraniol, can cause allergies in some dogs. The common thing is that the product indicates it. If you see that your pet’s skin turns red, remove his collar and wash the area with plenty of water. If you see that the reaction persists, you can take your dog to the vet for a solution to alleviate the allergy.

Additional features

Depending on the function that your dog collar fulfills, it may be accompanied by some extra elements or others that support that purpose. Sometimes they come with the product you buy. At other times you can incorporate them. In the following lines you will be able to understand what accessories to necklaces are available on the market and how they work:

  • GPS: Some training collars may include a GPS locator that lets you know where your pet is. These are controlled with a remote control, so the training of the dog is done without a leash.
  • Remote control: For collars intended for training, as they are used without the animal tied, the object is controlled with a remote control.
  • Ring: Necklaces made to go out for a walk have to incorporate one. Its utility is to be able to tie a leash to the collar. It can be a normal one or a training one.
  • Batteries: Both the anti-bark collars and some of those made to train, work automatically and are normally propelled thanks to the use of batteries.
  • Identification plate: If the collar is to go outside, it is advisable to put a plate on it that can help other people to identify the animal in case of loss. It is common to put a text as your name and a contact phone number.
  • Ice or freezing gel: If you are going to use a collar to cool your animal when there are high temperatures, inside the collar you can incorporate ice or gel bars that freeze.


It is very likely that your dog uses a collar and it is possible that, at some point of the day, he will have even more than one. Being such an essential element for your pet, it is good that you make a well-conscious purchase and that you know what the market offers, the options you have and what are the advantages or disadvantages of each collar.

There are collars for a myriad of different functions. Even if your only wish is to have your pet in fashion. Either way, a collar must be comfortable for your dog in terms of material, closure or the weight it has. Remember that it must be placed in such a way that it does not squeeze the animal’s throat and that it cannot be easily removed either.
