Why Frenchie owners pick Frenchies vs Mushrooms
- Seven mushrooms with amounts. 243 mg each. The two turkey tail products give you one mushroom; Pet Honesty gives you 14 with no amounts.
- Omega-3, turmeric and vitamin C on the same label, which none of the three single-purpose products include, and ours is flax, not fish.
- Made for a Frenchie's dose. One scoop for a 25 lb adult, half for puppies and sensitive stomachs. The capsule products dose per 20 lb and land a 25 lb dog between one and two.
- No chicken, no fish. The common Frenchie triggers stay out of the jar.

Questions Frenchie owners ask
Which mushroom matters most for a French Bulldog?
Turkey tail is the most studied for immune support and it is in all four products on this page. Reishi, shiitake, maitake and cordyceps appear in the blends.
Is a single-mushroom supplement better than a blend?
Better is the wrong word. A single mushroom is easier to measure and rule in or out; a blend covers more ground. If your Frenchie's issue is mainly itch and skin, a blend that also carries omega-3 and turmeric does more jobs per scoop. If you want purity, go single.
What does a proprietary blend mean on a mushroom label?
It means the label lists the mushrooms but not how much of each is in a serving. Pet Honesty lists 14 mushrooms that way. Frenchies vs Mushrooms prints 243 mg for each of its seven extracts.
How long before I see anything?
Weeks. Every one of these companies, ours included, describes gradual change. Give any of them a full container at the right dose before you decide.
We compare what each company prints on its own product page. Supplements support normal body functions; they do not treat, cure or prevent disease. Ask your vet before starting any supplement, especially for a dog with a thyroid condition, on medication, pregnant or under 8 weeks.
