Sisters and Bazzy’s Kefir founders Yumiko and Ayako have created frozen, pet-friendly treats that are free from allergies. Using the immunity-boosting effects of kefir, the sisters developed the new pet treats from the cultured probiotic, and it seems that it helped solve their dog’s skin problems. This set the sisters on their journey to create a health-conscious pet food brand that aims to shift the industry toward healthier foods.

Kefir Contains Friendly Bacteria and Has Many Science-Based Health Benefits Related to It

Kefir is often used as a probiotic because its friendly bacteria and yeast improve gut and skin health and act beneficially against allergies. Bazzy’s Kefir uses vegan-friendly coconut milk with kefir grains and produces treats that can boost immunity response, skin support, decreased inflammatory response, antibacterial & antifungal properties, and bone health. It also has great nutrients like vitamin B12, magnesium, calcium, folate, and more. Apparently, kefir provides more benefits for animals than yogurt and for a more extended period of time.

Kefir Has Been Made for Hundreds of Years

Many people do not know about kefir and its qualities, but it has been around for hundreds of years, and many use it today. Now, Bazzy’s Kefir has made the benefits of this product available for dogs as well. The company makes its new product by adding kefir grains to blueberries, peanut butter, and vegan-friendly coconut milk. Located in Southern California, it also offers its products on its website. After working with pet-friendly businesses in the area, the two sisters are now planning to add their products to local stores.

Bazzy’s Kefir maintains a good website where people can find information about everything related to animals, including tips on how to help pets with surgery recovery and a guide to the best dog parks in LA. The company clearly demonstrates that the people involved with it have a true passion and love for animals, as well as the environment. This shows in the products they make and their mission.
