Protection against (ecto-)parasites in dogs – what is helping?

Ectoparasites such as fleas, ticks, and mites are not only a nuisance for dogs, but can also transmit serious diseases like Lyme disease, anaplasmosis, or babesiosis.

Effective parasite protection is therefore an important part of preventative healthcare.

On this page, you will find a clear comparison of common preventative measures—from chemical preparations to home remedies—along with their respective advantages and disadvantages.

Why parasite protection is so important

Parasites can transmit pathogens, some of which can be life-threatening. Ticks play a particularly significant role, as they can transmit several infectious diseases simultaneously.

Fleas and mites can also cause severe itching, skin inflammation, and, in sensitive dogs, allergic reactions. Consistent protection is therefore not only for your dog's comfort but, above all, for their long-term health.

Chemical parasite protection

Chemical preparations are considered the most reliable protective measures against ectoparasites. Depending on the product, they differ in application, mode of action, and tolerability.

Spot-on preparations

Spot-on treatments are applied as a liquid directly to the skin on the neck. The active ingredients spread across the skin and are effective against fleas and ticks.

Advantages:

  • Easy to use

  • Fast onset of action

  • Broad spectrum of activity

​

Disadvantages:

  • Possible skin reactions in sensitive dogs

  • Highly toxic to cats in some cases

  • Requires regular reapplication

  • More expensive parasite protection

In households with children or multiple dogs, special attention should be paid to safety, fit and possible side effects.

Collars against fleas & ticks

Antiparasitic collars release their active ingredients continuously over a longer period and often offer protection for several months.

Advantages:

  • Long duration of action

  • No need for regular reapplication

  • Continuous active protection

​

Disadvantages:

  • Risk of skin irritation

  • Safety concerns when dogs play or have multiple dogs

  • Ingestion of the active ingredient through licking is possible

In households with children or multiple dogs, special attention should be paid to safety, fit and possible side effects.

Tablets (systemic parasite protection)

The tablets work through the bloodstream and kill parasites as soon as they absorb blood.

Advantages:

  • Easy administration

  • No external active ingredient

  • Long duration of action

​

Disadvantages:

  • Possible side effects (e.g., gastrointestinal, neurological)

  • No defense mechanism before the bite

  • Not suitable for all dogs

  • More expensive parasite protection

Natural remedies & home remedies – what is realistic?

Many dog ​​owners desire a natural alternative to chemical parasite protection. A realistic assessment of its effectiveness is crucial.

Coconut oil

Coconut oil is often used as a natural remedy against parasites due to its lauric acid content. However, the scientific evidence for its reliable effectiveness is limited.

Advantages:

  • Natural ingredients without chemical additives

  • It also conditions the coat and skin

  • Affordable and readily available

​

Disadvantages:

  • Limited effectiveness – not reliable protection in high tick populations

  • Frequent reapplication required

  • Allergic reactions possible

Amber necklaces

Amber necklaces are said to repel parasites through electrostatic charging. There is currently no scientific evidence to support this claim.

Advantages:

  • Natural ingredients without chemical additives

  • Can also be used as a decorative accessory

​

Disadvantages:

  • Very limited effectiveness – no scientific evidence

  • Insufficient protection

  • Not suitable as a sole measure

Essential oils

Some essential oils are advertised as natural parasite repellents. However, many of them are only suitable for dogs to a limited extent or are even toxic.

Advantages:

  • Affordable and readily available

  • Antiseptic and nourishing properties

​

Disadvantages:

  • Risk of skin irritation or poisoning

  • Protection is only short-term at best

  • Frequent reapplication required

Which solution is the right one?

The ideal parasite protection depends on many factors: age, health, living environment, and the dog's individual tolerance.

Chemical preparations generally offer the most reliable protection, while natural remedies should only be used as a supplement. It is important to check the effectiveness of the protection regularly and to seek veterinary advice if you have any concerns.
