Review: This works!! - We have 3 fur babies. 2 of them have sensitive skin and struggle with seasonal allergies . After adding this to their food twice daily the skin issues and allergies have disappeared!! We also feed them clean grain free organic dog food and do not give them unhealthy people food or snacks. The change has been AMAZING ! No more bumps or red itchy areas on the skin. Clean up the diet, use this in their food and you will see a change!! 10/10 stars for this product..
Review: Mushroom Blend with clean and organic ingredients!!! Paw-fect for my fur baby!! - I recently added Bark & Whiskers Mushroom Blend to my pup’s routine, and I’m genuinely impressed. What I love most is that the ingredients are clean and organic, no fillers, no unnecessary junk. Ever since I started giving it, I’ve noticed a softer coat, shinier fur, and more energy during walks. Also, digestion seems smoother. The mushrooms they use feel high quality, and the powder mixes well in her food, without altering the taste or texture. If you want something natural and powerful to support your dog’s overall health (skin, coat, immunity), this Mushroom Blend is definitely doing its job, worthy of 5 stars!

## Questions & Answers

**Q: How many ounces?**
A: 8 ounces.  our 27 puond dog gets two scoops per day (scoop comes i n jar) and it lasts about one month.

**Q: How long does this last?**
A: It depends on the size of your dog or cat.  My dog is 93 pounds.  I give him just a little under a Tbsp. a day on his dry kibble mixed with water.   One jar will last me about one month.  This is the largest serving size at 2 1/2 scoops.  If you dog is smaller it will last longer.

**Q: Why does this product have warning: california’s proposition 65 ??**
A: Mushroom Complex contains naturally-occurring lead that is found in low amounts in some of the plant-based ingredients we use in the supplement. Lead is naturally present in the soil, and as such, it can accumulate in certain plants. Dr. Mercola is aware of this but feels that the benefits that can be gained from taking the product far outweigh any risk associated with the minute amounts of lead in the product.

**Q: Why are so many different mushrooms used in this one?**
A: I believe that this combination gives the advanced immune support that is needed for an anti-cancer regimen.  The Reishi especially is known in Japan to actually reduce the size of cancer tumors. I'm using this on my dog who has had adrenal carcinoma and is doing very well.

### ⭐⭐⭐⭐⭐ Good product. Seems to reduce fatty tumor growth
*by L***A on February 13, 2026*

Really has seemed to help significantly reduce the fatty growths my dog has developed. Haven’t noticed any new ones since consistently feeding him this with his dinner. He’s 10.5 years old now. I had noticed 1 skin tag but no new other growths which he used to have many of.
