River & Wren botanical blends can be used alone, in rotation, or in a combination with any of River & Wrens additional botanical blends and toppers. Our blends contain naturally dried whole-food herbs that promote an unsavoury environment for pesky biting insects. Our toppers are expertly crafted, using herbs that deter fleas, ticks, mites and other biting insects. We recommend you start to use this topper from Feb to Oct. Botanical flea & tick blend can take six weeks to become effective.
Directions:
Before use, shake the pot. This versatile product can be added directly to the bowl or mixed with water, kefir, bone broth, natural yogurt, raw, cooked or wet diets, to create greater palatability. 
Recommended guidelines:
1 teaspoon per 10kg bodyweight. 
Always consult your vet if uncertain. Not suitable for pregnant or nursing canine mothers. 
Our recommendation is to commence the usage of our flea and tick topper no later than six weeks before spring until end of autumn. It's also important to take a break during the winter.
