Medicinal Mushrooms
This powerhouse blend of four medicinal mushrooms has been used for centuries to support immune health — and modern science is catching up. These mushrooms contain beta-glucans and other bioactive compounds that help activate your dog's natural immune defenses, promote healthy cell function, and support overall vitality. Together, they work to strengthen your dog's body from the inside out so they can fight off threats before they become problems.
Goji Berry, Rosemary & Flavonoids
Packed with potent antioxidants, this trio helps protect your dog's cells from oxidative stress and free radical damage — two of the biggest contributors to aging and immune decline. Goji berries deliver a concentrated dose of vitamins and minerals, while rosemary and natural flavonoids create a protective shield around your dog's cells, helping keep their immune system sharp and their body resilient no matter their age.
Echinacea
Known as nature's immune booster, echinacea has been trusted for generations to help the body mount a strong defense against invaders. For dogs, it helps stimulate the production of white blood cells — your pup's frontline soldiers against illness. Whether your dog is fighting off seasonal challenges or you just want to keep their immune system in peak condition year-round, echinacea provides the natural support they need.
MSM & BCAAs
MSM is a natural sulfur compound that helps reduce inflammation and supports comfortable joint movement, while BCAAs (branched-chain amino acids) fuel muscle recovery and help maintain lean muscle mass. Together, they ensure your dog stays active, mobile, and strong — so they can keep up with walks, playtime, and all the adventures that make life worth living.
Magnesium Citrate
This highly absorbable form of magnesium plays a critical role in over 300 biochemical reactions in your dog's body. It helps relax muscles, supports a balanced nervous system, and promotes calm behavior — making it especially valuable for anxious or high-strung dogs. Plus, magnesium strengthens bones and amplifies the effectiveness of the other ingredients in this formula, ensuring your dog gets the maximum benefit from every single scoop.

Not sure about the Tummy chews. The K9 immune is good. I'm hoping it gets rid of the fatty lumps on Tucker.
I just received this stuff.Haven't really had an opportunity to use it to see if it works or not.It's pretty hard to judge something the packaging is fine.I'll let you know more after we've used it
this really works. I already use your ear cleaner. Paired with the immune powder it is really making a difference
Immune support has been great, but I actually had to stop giving it daily to my 2 year old. He seems constipated. It has firmed up my 15 yo’s bm’s also and he’s had diarrhea for 9 months. Not completely there, but working on it
It seems to help My grand dog feels a bit better. He is going to be 11yrs in January. He has arthritis and has slowed down some. But since I started use the K9 Immune powder he seems to be getting around better. I know it’s for other things as well. Thank you
My Winston has been taking it for about two weeks now and he seems to be more energetic and happier since he's been on it
Great product but upsets my dogs stomach.
Sophie is a large chocolate lab. We live on a ranch and she would play hard and then be unable to move for a few days. She would try and lift both hind legs, not jump to her favorite sleeping spots, and was visibly uncomfortable. We did not want to keep giving her prescription pain meds. We started trying this product and got her the chews as well. Over the next few weeks she gradually improved. Now she acts several years younger and is a HAPPY fur baby! Thank you for giving her a quality life back🐕🦺🐾🐾❤️
My dog enjoys the flavor and eats every bite
Dogs love it !
Charlotte is eating well and most of all eating her food with K9 in in it. We are hoping the lumps shrink or go away, but they are still there' She has been eating and that's a plus. We will keep you posted about my baby girl. Thank you for the follow up Mary
So far I feel like this product is helping my dog.
Excellent product and service
Our older GSD loves the K9 Immune. The big fatty lump on her chest has started to decrease a little. She has way more energy and the K9 Immune must taste good as her appetite has increased after the first month. I saw her running for the first time in years. Great product Fer sure!!
Hopeful
Seems to have added a little pep to my 11 year old terrier's step!
Make sure you have taken this account off of automatic refill
My dog is doing better with the product
Love the product
Seems to be helping
My puppies consist of 7 months old to 15 years old. They all have had a boost in energy. They seem happier and are definitely more vocal. K9 immune support has been very good for our puppies. They thank you and I thank you.
My dogs feel so much better when this is a part of their diet. They both have yeast overgrowth issues and this seems to help.
"DIXIE" is my 15 years old mainly Manchester Terrier, the one for whom I'd made this order, due to the developed pouch within one side. It has begun to go away, now that she's taking this aid regularly-!
Manny is less itchy, but not completely. Still on guard daily for ear "gunk" Have EarDog Cleaner- do 2x/day Have made the cookies , etc
Millie seems to love it in her food! Hope it works for her.
Here’s the detail on this one. Yes, it is helping in lots of ways. She does have more pet back into her. But she is still scratching. And the lumps on her side and a new little one on her back. I don’t think they have gone away. And I don’t know if it’s just this one or that one that happens to be the tummy one that happens to be helping her in regards to she doesn’t have much of diarrhea anymore, but she is going like a dog but a couple times when she does go. And I forgot to add we still have a whole bag and half of a bag left.
I started using the immune support in the hopes of helping my elderly dog, Cass, with his numerous bumps & lumps he had developed in recent years. But we have 6 dogs & I have given it to them on their food daily for a month. First, Cass’ eyes (which were always runny, full of tears & oozing goopy stuff) cleared up so nicely! Bless his heart! I know he feels much better because of it. Second, my dog, AT, was always scratching. He has the most beautiful brindled coat & didn’t have fleas. But he was always scratching. This immune support has helped his itching immensely! We will continue to use this wonderful product to see what other issues it can help the dogs with. Hopefully, we will soon notice a difference in Cass’ lumps.
Vode eats all his food. With no problem. So,far. Thanks
really to soon to tell
The k9 Soothe works well .Stops itching fast praying my baby gets well soon it hurts to see her going through this and everything I have tried so far has not worked as good as k9 Soothe just hope I can afford to keep it up until she gets well unfortunately my budget is tight at the moment
Seemed to help size of bumps
My pups seem to be healthier and more active. Love this product.
Sam is 14 years and has many health issues and as of late since being on Immune Support has a noticeable pep in his step. Thank you so much for giving him a good chance for a longer and better life!
Well, I was not sure dogs would love it . I was expecting them to put their nose up to the powder . I was shocked, they love it Well I’ve been putting on food daily for the past week and noticed an increase in energy . No lumps gone yet, or decreased in size, but I will update after it’s been in their system for a while.
Our doh has no problem with it
I started few months ago bumps on her back...Dog Immune support, Dog Dental powder & K9 Belly Bless from Pup Lab still waiting to see results !
My dog just love it Thank You
I have seen a remarkable difference in my 12 year old golden. It has helped him so much
Marlee loves the product, I sprinkle it on here food and she laps it up.
