My dog Roscoe is extremely sensitive and picky, and I've tried various products. These are the only ones that seem to be making a difference. Because he is picky, I sometimes put the contents of the capsules in his food, or at times wrap the capsules in peanut butter. That's been working well. I am hoping this continues to improve his general health, as my Vet told me that mushrooms have strong immunity benefits. Great supplements, excited to explore this brand more.

I decided it was a good idea after much research to start my dog on some supplements. Rooted owl was a great choice and had everything I was looking firbin. An immune supplement. My dog takes them with no issue, hes been much more active and energetic as well as generally all around well being seems to be up. Im very happy with the results so far, I will be trying to joint supplement next.
Not a Hit With My Pups
Rooted Owl was total failure with my pup Megan. She apparently didn’t like the taste or smell and wouldn’t eat it even if the capsules were wrapped in cheese.
Rooted Owl was total failure with my pup Megan. She apparently didn’t like the taste or smell and wouldn’t eat it even if the capsules were wrapped in cheese. She picked the cheese off and left the capsule multiple times. Didn’t try it with Emley my border collie as she’s on seizure meds and I didn’t want to mix it with those.

Love the rooted owl supplements and this one for general immunity is great. My smaller dog is a picky eater so I try to hide the capsule in his food or at times with peanut butter. Have seen great results!
Clean Ingredients Pack a Punch!

I had originally planned to give this supplement to my 7-year-old cat, but the size of the capsule was bigger than I could get him to take. Also, the product details on the Chewy website said to avoid breaking the capsule and spreading the contents on food, so instead I gave them to my dog (easily disguised in a bit of cheese). What I really like about this supplement is how clean the ingredients are. No fillers, and the only inactive ingredient is the capsule itself. While we haven’t seen the benefits yet (takes 2-8 weeks), just the fact that he takes the capsules willingly is a great first step! It’s a great supplement for allover health, and specifically mentions using during the winter, so our timing is perfect. This brand also has other supplements for other conditions that are worth exploring as well.

These are great mushroom ingredients from Rooted Owl. My dog takes capsules daily with the food and likes the flavor. Mushrooms are meant for general immunity and inflammation and plan on using it daily!

I have a new found love for mushrooms especially since i recently lost one of my pups to cancer. That rough experience lead me to learn more about mushrooms and their health benefits to dogs. These capsules are nice and convenient for dosing accurately (according to the products labels) i personally break mine open and sprinkle them into my dogs food which he doesnt seem to mind and mix into the wet food for my senior dog who also doesnt seem to notice or mind!

Arrived on time and packaged well. Powder in the form of capsules which are large so you’ll have to open them and mix the powder in their wet food. My one cat is eating but the other one is not. I guess they can smell something is different. Not sure how to rate this since I do not know if it’s actually making a difference in their health or not so gave 3 stars.

I have been using these pills on my 2 dachshunds and Chihuahua. They all suffer from allergies. After 2 weeks of taking it, I noticed they are not scratching and they are eye booger free. The capsules are hard to open but once I did, I mixed with their food. They all ate it with no complaint. I would definitely continue with this product.

So far we are enjoying the use of this vitamin for our cats! Unfortunately only one of ours was willing to eat her food with it crushed up on top, but since she tends to has seasonal allergies and sicknesses, this is a product I would consider and continue to use for her. Plus I love that it has minimal ingredients!
