Introducing Mirai no Hitosaji: A Senior Pet Supplement for Aging Dogs and Cats

Introducing Mirai no Hitosaji



On July 7, 2026, Dog Diner Co., based in Tokyo, launched a trial size of its popular supplement "Mirai no Hitosaji," specifically crafted for senior dogs and cats experiencing joint and liver health issues. The new 5g sample, priced at 998 yen, is available at the official Dog Diner store on Rakuten Marketplace. This high-quality supplement is not just limited to home pets; it's also employed by racehorses at Ooi Racecourse, solidifying its reputation in both domestic and professional settings.

What is Mirai no Hitosaji?



"Mirai no Hitosaji" is a premium, additive-free, and domestically produced powder supplement featuring key ingredients such as Agaricus (Brazilian), shark cartilage (Japanese), and chitosan (Japanese). Tailored for senior dogs and cats, this versatile powder can simply be sprinkled over their regular food, effortlessly supporting their joints, hips, liver, and overall immune system from within. It particularly appeals to pet owners seeking a holistic care solution for their aging companions.

Trusted by Professionals: Used by Racehorses



This supplement is recognized for its utility in the competitive world of horse racing. It has found favor among professional handlers at the Ooi Racecourse, where maintaining optimal physical condition is non-negotiable. The use of a product designed for elite racehorses in family pets showcases its effectiveness in supporting joints and hips. Now, pet owners can provide their senior dogs and cats with the same trusted supplement used in professional settings with ease.

The Introduction of the 5g Trial Size



The launch of the 5g trial size is a strategic step to ensure that older dogs and cats will readily consume the supplement. Before committing to the standard 50g package, pet owners can test the waters at a manageable price. The small trial size is excellent for picky eaters or those with concerns about their pet’s appetite, making it an accessible option for a first experience.

Comprehensive Care for Senior Pets



Mirai no Hitosaji has been designed to address multiple health concerns faced by senior dogs and cats. The formula features 10.4g of mucopolysaccharide chondroitin and 15.2g of collagen per 100g, which aids in joint and hip health, while 2.8g of beta-glucans from Agaricus support the immune system. Many owners choose this supplement after noticing symptoms such as wobbly hind legs or changes in walking behavior, making it a popular choice among those caring for aging pets.

Human-Grade Quality You Can Trust



The product is noted for its commitment to quality: it is made with domestic, additive-free ingredients, and contains no artificial colors or fragrances. Sourced from organic and pesticide-free materials, Mirai no Hitosaji meets human-grade standards, ensuring peace of mind for pet owners who might worry about their pets consuming the powder entirely. This makes it a repeatable option for those seeking a reliable senior supplement for their dogs and cats.

Starting Early with Senior Care: Ideal for Pets Aged 7 and Up



While the supplement can be effective after aging signs appear, it is ideal to begin administering it proactively once pets reach the age of 7. Mirai no Hitosaji can be tailored for all breeds, from Chihuahuas and Dachshunds to Golden Retrievers and Maine Coons, by adjusting the dosage according to weight. This flexible approach ensures that it is suitable for both young and old pets alike.
