There is no difference in the ingredients of Real Mushroom Human Products vs Real Mushroom Pet Line. (continue to read labels)
The variance is volume of product and dosing. If you have large dogs or multiple dogs ordering human versions of the product may be effective.
When you order Mushroom powders, they are generally easier to add to your dog’s food and create the right dosing than capsules. Just be aware too much “powder” in your dog’s food bowl may change the texture (require more water) and taste of food making it more difficult to get the dog to eat. Having said that – my dogs don’t seem to mind mushrooms at all
Tinctures (ie Myco Dogs) can sometimes be easier to dose if your dog is not eating well, but they may not be as economical.
You may have to experiment for your dog (or yourself) and perhaps even combine tinctures and powders as needed.
Like everything we talk about – quality of the product matters.
