What do I do with the inner piece of the collar?

This piece is necessary during the injection molding manufacturing process but it needs to come off before putting the collar on your pet. You can either throw it away or, as this piece is active and also full of natural repellent active ingredients, place it under the rug of your front door or inside the dog house or any other place to help prevent pest infestation.

Is the cat collar a breakaway design ?

Our collar has a breakaway system (punctured hole to make the system more fragile) designed to break under the strength of a struggling 4.5 lbs cat, which corresponds to a 120 Newton force and which is sufficient in nearly all circumstances. To date, we have shipped millions of cat collars and fortunately, not one incidence of accident has been reported.  Although we are able to produce a weaker breakaway collar, we are convinced consumers would prefer the current design since the weaker style will on occasion break too easily and be at risk of breaking even as the collar is fitted on the cat.

Why are we moving to natural repellents ?

Main reason : Flea collars containing organophosphates are dangerous for both humans health, especially children health, as well as pets health. That is why, the French National Agency of Veterinary Medicine decided to withdraw the permit for sale of Diazinon, Propoxur and TCVP based collars, that are still widely commercialized in America. More recently, US EPA decided to ban Propoxur-based collars.

Indeed, while adults or children are petting your animal, insecticides are absorbed through the skin and may harm the nervous sytem. It is the same for pets.

Thus, we have developed natural repellent products to take care of people and animals' health.

How can we fight against fleas? The key : Prevention

There is no need to treat with powerfull insecticides as the flea is easily eliminated by common insecticide, but there is a need to treat often and everywhere, using a preventive approach. Often, because the fleas which have survived to the initial treatment (because under the form of the more resistant egg or nymph development stage as seen previously) have to be also eliminated to avoid an other infestation. Everywhere, because fleas, larvae and nymphs are deeply entranched in the carpets, pillows, furniture tissus, etc.

We advise to use household insecticides to be sprayed regularly on surfaces that are proned to have fleas, larva and nymphs (dog house).

The vaccuum cleaner also helps diminishing the numbers of eggs and nymphs. One method is to vaccum just after spreading insecticide powder to prevent fleas from multiplying themselves inside the vaccum cleaner bag. 

Pets bedding are typically a flea nest. You can either change them, which would be the best, or take advantage of the summer to put them inside a plastic bag with a good dose of repellent powder inside.

Some laboratories propose some more elaborated products. These formulations are said to be long lasting: they are typically effective over several days or several weeks. These are interesting products as you do not have to treat as often and they guarantee the insects elimination. They are obviouly more expensive than natural repellent products and most of them have health issues associated with. Please let us know what you use and we can send you the toxicology profile of the active you are using.

There are also specialty products containing an active ingredient preventing the larva to develop into its nymph form, which is the morst resistant form. Recent studies have been performed inside our laboratory to show that these products are effective but last a relative short period of time. Furthermore, they are very expensive. They can be purchased under gas propelled spray that is a one time use.

For "industrial" surfaces, such as garages, gravel, we can use stronger chemical or physical treatments (lime, sodium hydroxide, fire,...). Fire treatment is perfectly suited for large cement surfaces such as the ones found in kennels. 

You then need to avoid that the insects re-appear. The best in that case is to protect the potential carrier.

You need to effectively treat all your pets at home with a repellent collar for instance and if possible ban the access to your house to foreign animals. A new pet you are bringing in needs to be systematically treated.

Overall, the most efficient way to fight against pest is the preventive way : prevent the pest from coming instead of fighting it when it has already nested in your home and pet. Our natural repellent line is particularly suitable for this purpose. And because it is safe, there is no concern with the frequency of application (following packaging instructions) as opposed to synthetic insecticide products.

Can the fleas attack the human beings ?

In general no, but certain people are an exception and are "devoured" by fleas.

In these cases, bitings generally occur around the ankles and the calves and appear themselves as small red stains which strongly itch.

If it is the case, consult your doctor and start a complete desinfection and clean-up of the house.

How do repellent or insecticide collars work?

Collars advanced technology is using the properties of some specific plastic materials.

The active ingredient is incorporated inside the plastic matrix itself and is being released from this matrix under a constant speed over a long period of time. The active ingredient migrates to the surface of the plastic under the form of micro drops or powder depending on the active molecule. Since the release is very slow, the product can be effective for several months.

At the end of the product life, the content of the active ingredient inside the plastic is very small and the collar is becoming more rigid; you then need to replace the collar with a new one.

How a flea collar carried around the neck of my pet can protect its whole body?

When we touch a window or a mirror, we leave a print. It is due to a fat called the sebum which soaks our epidermis and our skin. The sebum has a very important role; it is in particular a nutritive and softening factor for the skin.

The skin of the dog and the cat is also covered with sebum. It is this sebum which will transport the active ingredient. Indeed, the molecules used in the collars are very soluble in the sebum. They will diffuse via this fatty layer on the whole surface of the body. Thus, a flea collar carried around the neck protects the animal completely, from the head to the tip of the tail.

My house is infested with fleas. Despite all my efforts, I cannot get rid of them. What can I do ?

It is quite difficult to get rid of fleas from the house. Different from what most people think, fleas do not live permanently on the animal but on the floor, on carpets, pillows, etc...

Fleas generate eggs. From the eggs, a larva follows different development steps to turn into a nymph and to finally become an adult insect. Nymph are inside a cocoon and they have the particularity to stay "asleep" a very long period of time and to turn into an adult insect after some time that can last for several months. It is the reason why we can see fleas appear in a house left empty for several months in the absence of animals.
In that case, these nymphs can wake-up, for example when they start feeling vibrations on the floor.

The adult insect has to bite a target (a dog, a cat or an human) in order to feed himself with blood. After feeding, the flea is falling on the floor where it lives and deliver its eggs. And so on....

Fleas and larva are affected by most of the common insecticides: insecticides used on animals (collars, powder,...) or household environment insecticides. But we still recommend to follow the preventive approach with natural repellent products before the season starts. It is healthier and preventing is much easier than fixing the problem !

However, the eggs are not affected by those and nymphs are quite resistant to those.

So an effective treatment consists in breaking the flea cycle and to prevent the fleas to deliver new eggs.

I treat my dog or my cat with an insecticide product (shampoo, powder or spray), he/she wears a collar and he/she still has fleas. How can it be possible?

If it is the case, it probably means that the environment in which your pet lives is infested with fleas. As a matter of fact, and different from the common belief, fleas do not permanently live on the animal. Fleas are more often on the floor, in carpets, pillows, etc... Fleas "jump" on the animal only when they need to be fed with blood.

The treatments you are using kill fleas that are present on the animal. But as there are a large amount of fleas in the environment, new ones replace dead ones giving the impression the products are not effective. Therefore, THE ENVIRONMENT NEEDS ALSO TO BE TREATED.

Once it is treated, you will have to prevent fleas to come back by treating them as soon as they re-appear with a shampoo, a powder or a spray. Ideally, you will permanently have on your pet a collar. You would need to replace it at the end of its life as described on the packaging; it would permanently protect your pet against fleas.

Can I use a soft shampoo for baby to wash my dog ?

Dogs are distinguished from humans by their skin much finer and thus more fragile: dogs skin comprises 5 layers of cells corneas different from the human skin which comprises 9 of them.

The other difference relates to the pH. The human skin has an acidic pH of approximately 5.5. The human shampoos take it into account and are also acidic in general.
On the contrary, the pH of dogs skin is rather basic (between 8 or 8.5).

The human shampoos, even soft, will not respect the balance of the pH of the dog skin and it is consequently not advised to use them.
Even for an adapted shampoo, it is necessary to avoid too frequent washings. A skin washed too often will become very fragile and sensitive to eczemas. One or two shampoos per month is a maximum frequency. In the event of local "accident”, you can always locally use a lotion “without rinsing”.

The dry shampoos make it possible “to cleanse” and to scent the hair without wetting the animal and subjecting him/her to aggressive detergent agents.

I already have products for my dog; can I use them for my cat ?

Not at all !

Cats and dogs do not belong to the same species and they are as different from each other as a rabbit from a horse !
Especially, they have a different metabolism and a different physiology. In other words, what can be safe for one, can be a deadly poison for the other one.
Cats are fragil animals and a large number of chemical substances cannot be eliminated by their liver.

So, it is very dangerous to take a risk in regards with this question; numerous cases, some with tragic ends, have happened. 

It is the reason why you need to use the products specifically designed for your pet. They have been studied and developped to be safe to their health and for their well being.

If you have any doubt, please contact your veterinarian before doing anything. He is a specialist and he will know how to direct you.

What can I do if I feel the collar scent is too strong?

It is sometime difficult to develop a natural collar which is both effective and odorless. If you feel the scent is too strong, you can first leave the collar out from the packaging from 1 hour to 1 day outside before putting in on your pet. Then you can also remove it when your pet is inside your house and put it back when he/she goes outside. And remember to wash your hands with soap after handling it.

Can I use Alzoo collar with different product brands?

If you have used another natural-based brand of spray or spot-on within the last 15 days, shampoo the fur around the entire collar area prior to using the ALZOO Collar. (Since ALZOO Collars, Spot-on, and Spray have been developed so that they can be used together, this is only required with another natural brand).

Is the collar waterproof ?


Is the spot-on waterproof ? Can I wash my pet with shampoo after applying the spot-on ?

Yes and no. The spot-on is formulated with almond oil. Almond oil has 3 purposes:

a- protect the skin from the active

b- help diffuse the active throughout the skin

c- protect the active from rainfall.

So if your pet is outside when it is raining, the active will not disappear as it will be protected by the almond oil, which is water resistant. But if you wash your dog with a shampoo, the shampoo will "dissolve" the oil and a spot needs to be re-applied after you wash your dog.

The spot-on appears oily. Is it normal ?

Yes. Almond oil has real benefits: a- protect the skin from the active, b- help diffuse the active throughout the skin and c- protect the active from rainfall. If you want to minimize the oily sensation when applying the product, space out the hair and apply slowly directly on the skin in the back area of the neck; then go down the spine of your pet and apply slowly while avoiding to put too much product on one spot. That way the product will be well dispersed and adsorbed on your pet skin.

If you see a stain on fabrics coming from the spot-on, a classic stain remover, degreasing agent will easily remove the stain.

How do I know I poured half a tube for small dogs ? 

Half a tube corresponds to about 60 drops.


What size of flea sport or flea collar product to use for a given size of dog?


For our product, we advise :

-small size <35lbs

- medium size: 35 to 74 lbs

- large size for more than 74 lbs

What do I do if I have hard time fastening the collar ?

If you are experiencing this, we suggest adding just a little bit of vegetable based cooking oil to the buckle (either 1 spray, or 1 drop or you can rub it on with a Q-Tip). This should make it easier for the collar to pass through the buckle.
