Common Uses

Fennel seed is great for cases of flatulence, and has a more palatable flavour for cats and dogs who dislike mint.

Fennel is also high in vitamins and minerals, making it a good supplement to your pet’s diet. It can also increase appetite and reduce bad breath due to antibacterial properties.

Fennel leaf tea can be used as a skin and coat rinse for repelling fleas.


For relief of chronic cases of gas, fennel can be added directly to the animal’s food.

For relief of acute cases of gas, a cooled fennel tea made from 1 teaspoon of fresh or dried seeds in 8 ounces of boiling water can be fed at a dose of 2-4 tablespoons for each 20 pounds of the animal’s body weight, or added to the drinking water. A glycerin tincture also works, at a dose of 10-20 drops per 20 pounds of animal’s body weight.
