Austin and Kat expands functional mushroom line for dogs
Bottom line
Austin and Kat has expanded its functional mushroom line for dogs with three whole-mushroom powders and two concentrated liquid extracts, broadening a category that had already been part of the Seattle company’s supplement portfolio. The new products include powders for Lion’s Mane, Turkey Tail, and a multi-mushroom blend, plus liquid extracts led by Lion’s Mane Extract and 6 Mighty Mushrooms. Austin and Kat says the products use organic mushroom ingredients sourced from M2 Ingredients and are available through its wholesale site and distribution partners. The company, founded in 2014, also highlights that it manufactures in its NASC-certified Seattle facility and operates as a 100% employee-owned brand. (petfoodprocessing.net)
Why it matters: Functional mushrooms keep gaining traction in pet supplements, especially as brands push formats that mirror the human wellness market, including powders and liquid extracts. For veterinary professionals, the expansion is another sign that pet parents will keep asking about mushrooms for immune, cognitive, gut, and aging support, even though the evidence base in dogs remains uneven and product quality varies widely. That puts more weight on counseling around realistic expectations, ingredient sourcing, manufacturing standards, and the difference between marketing claims and clinical evidence. (chewy.com)
What to watch: Watch for whether Austin and Kat builds retailer distribution, adds species-specific claims support, or points to new canine data as the functional mushroom supplement market matures. (nutritioninsight.com)
Austin and Kat is widening its push into functional mushrooms with five new dog supplements: three whole-mushroom powders and two concentrated liquid extracts. The launch extends the Seattle company’s move beyond its better-known hemp and CBD lines and further aligns the brand with a fast-growing wellness segment that is increasingly showing up in pet supplements, treats, and toppers.

The company’s backstory helps explain the move. Austin and Kat was founded in 2014 by Kat Donatello and built its early identity around hemp-based pet wellness products. Today, it describes itself as founder-led, employee-owned, and manufacturing in small batches at its NASC-certified Seattle facility. The mushroom expansion appears to follow the same playbook the company has used elsewhere: premium positioning, controlled sourcing, and a formulation story aimed at pet parents who are already comfortable with supplements as part of everyday care.

According to Pet Food Processing and Austin and Kat’s own mushroom materials, the new lineup includes single-species powders for Lion’s Mane and Turkey Tail, a blended powder, and two liquid extracts, including Lion’s Mane Extract and 6 Mighty Mushrooms. Austin and Kat says it sources organic mushroom ingredients from M2 Ingredients, which it describes as a transparency-focused supplier with controlled cultivation and science-based extraction capabilities. On its site, the company positions powders as minimally processed whole-fruiting-body options, while describing liquid extracts as more concentrated and easier to absorb. (petfoodprocessing.net)
That positioning also reflects a broader market shift. M2 Ingredients has been expanding its role in companion animal applications and recently partnered on distribution of mushroom powders for pet food, treats, and supplements targeting gut and immune health. Industry coverage this year has framed functional mushrooms as part of a larger “human-grade wellness” trend in pet products, where pet parents increasingly look for clean-label ingredients and condition-specific support.

Expert commentary remains more cautious than the marketing. Veterinary and expert-reviewed sources note that mushrooms such as turkey tail, lion’s mane, reishi, shiitake, and cordyceps contain compounds like beta-glucans and other bioactives that may support immune, digestive, or cognitive health. But they also stress that the clinical evidence in dogs is still limited, with stronger support for some use cases than others, and that supplement quality can vary significantly by sourcing, processing, and labeling. UC Davis’ veterinary supplement guidance likewise notes that pet supplements do not need premarket proof of efficacy or safety in the same way drugs do. (chewy.com)
Why it matters: For veterinary professionals, this launch is less about one brand and more about what’s coming through the exam room door. As more supplement companies add mushrooms in multiple formats, clinicians can expect more questions from pet parents about cognition, immunity, GI health, cancer support, and healthy aging. The practical issue is that interest is outrunning evidence. That means veterinarians may need to focus conversations on intended use, concurrent medications, adverse-event risk, manufacturing oversight, and whether a given product is being used as a wellness supplement or as a substitute for evidence-based treatment. (chewy.com)
The other takeaway is competitive. Austin and Kat’s use of an established mushroom supplier, plus its emphasis on NASC certification and in-house manufacturing, suggests that quality signaling is becoming a bigger part of the functional supplement pitch. In a crowded market where many products make similar wellness claims, brands may increasingly differentiate on testing, extraction method, raw material sourcing, and practitioner trust.

What to watch: The next question is whether the category develops stronger veterinary-facing evidence and clearer standards. Watch for retailer uptake, additional species or condition-specific launches, and any new canine research that helps separate broad wellness positioning from clinically meaningful use cases.
