The normal way in which a dog would receive a flea treatment would be oral tablets, topicals, shampoos, and collars. Oral tablets are consumed by your dog eating them, either alone or mixed with their food. Topical delivery is usually achieved by the application of the liquid on your dog’s back usually from the neck region, shampoos are usually applied while bathing your dog with them, and collars are usually placed for a longer period around your dog’s neck.

With this in mind, you will need to consider your dog’s characteristics and behavior before choosing a method of delivery. For example, a dog that is always getting wet cannot be receiving flea treatment through the topical method. Oral Tablets are best for them.

A last word of note, even though using the collar method is still in use, the latest happenings have put a huge health concern question on them. We would advise all to tread cautiously with them for now.


It is no secret that insecticides that can kill insects are used to make flea and tick products. With that in mind, it is important that you do your own research to verify which kind of chemical is being used in the product you are interested in and verify for yourself that these chemicals would not be harmful to other people or pets in your household.

For example, it is a known fact that some of the flea and tick products used for dogs are actually very harmful to cats. Some are known to initiate allergic reactions in children.

When not so sure, always consult your vet doctor for directives.


Products usually come with expiry dates and flea treatment products are no different. Apart from the expiry dates, they should have a frequency of application on how often to apply it to your dog. Some may need to be applied weekly, others may need to be applied monthly. It all depends on how long the treatment remains potent in the dog.

This also affects how much you will pay for the flea treatment product you want.
