Our Story
It all began in 1994, with our rescue white lab, Winston, who was diagnosed with arthritis and hip dysplasia. Several vets recommended putting him down, but this was never an option for us.
We began researching alternative medicine while working with Dr. Pedro Rivera, a renowned holistic veterinarian.
After several months, we developed a natural joint formula that gave Winston a second chance at life. Winston went on to enjoy 10 long years of playing with his brothers.
We soon found others who wanted only the best for their pets as well—and that’s when NaturVet was born.
Who are we?
We’re NaturVet! One of the longest-operating and top-trusted pet supplement providers in the nation.
What do we do?
We make supplements that help pets and pet parents live their best lives together. From skin and coat to joint and digestive health to calming aids, NaturVet has everything you need to improve the quality of life of your four-legged friends, from nose-to-tail.

⭐️⭐️⭐️⭐️⭐️ Great Immune Boost for My Dog!
I started giving NaturVet Mushroom Max Advanced Immune Support to my senior dog a few weeks ago, and I’ve already noticed a difference. He seems to have more energy, and his coat is looking healthier too. I love that this product includes powerful mushrooms like reishi, shiitake, maitake, and turkey tail all known for their immune-boosting benefits.The chews are soft and smell a bit like mushrooms, but my dog actually loves the taste and thinks he’s getting a treat! I also appreciate that it includes antioxidants like vitamin C and milk thistle for liver support.It gives me peace of mind knowing I’m supporting his immune system naturally, especially as he gets older. I’ll definitely be keeping this as part of his daily routine.Highly recommend for anyone looking to support their pet’s health with a clean, vet formulated supplement!

This Works!!
This is amazing. Has shrunk my pups lump more than half the size with the first container. He’s also more alert and looks for his walks again. Doing much better for an 11 year old lab mix that had a hard start to life.

It gets rid of the lumps over time
It took about 3 months and this lump my Yorkie had on his back started to go away! After 4 it’s completely gone! The only reason I give 4 is because it is not the softest chew. If you have a Yorkie or a dog who is extremely picky about what they eat, just hide it in something, that’s what I do. I cut one cube up and hide it in his food or one those dog treats made for giving dogs medicine lol.

Obviously best mashrooms for dogs
My senior corgi has a tumor in his nose and I decided to do everything possible to support his immunity system in this fight.Mashrooms are well known supplements too boost immunity system. I was looking on different brands pills/powder/chewable supplements and obviously this one is the best. If you compare ingredients it has in just 1 chewy with other brands – you will see significant difference.The condition of my dog now is stable. I was giving him twise dosage of mashrooms for last few months and I think I can turn to normal dosage now. I do give him a lot of other supplements that all together make his life way better.They are not super soft and time to time my corgi didn’t want to chew them (maybe chewing makes pressure on his tumor that is not visible but is inside of his nose). So I just cut them and mix with yogurt when I give it to him with black and blue berries that as well boost his immunity system.Doctors were saying my dog most likely has cancer and his life term will be about 3-5 months.As today it’s 6-7months since we started to fight for his life – his condition is very stable comparing to what it was before. His nose doesn’t bleed anymore, he is active, eats and drink as normal dog, likes to walk and it’s hard to tell he has any problems untill the night… when he starts to snore because one of his nasal is blocked.If you need to boost immunity system of your dog – I highly recommend this supplements. If your dog will not chew them – it’s always the way how to trick the dog.Defined best value of money and perfect size!

Love this product.
Teddy loves these! It’s a treat for him. Just ordered our 2nd jar. He is 10 yrs now so I’m doing what I can to keep him youthful. People can’t believe his age. He looks and acts like a puppy.

My labrador…
My dog,a labrador is 11yrs, she eats most things….but had to cover in peanut butter for her to eat. She vomited the 2nd day. She has vomited maybe 4x in her life.
Critic is an Old Man –
Not worth the maintenance
This was fun even if impractical
sandra J. Harrison –
Healthy addition to her food
She is very healthy and her bowels are good. She is 5lbs and gets only a piece of the cube each day in her food. She eats it readily mixed in food.
Amazon Customer –
My dog does not like them, but I hide it in peanut butter, so she is getting the benefit. She has a tumor in her throat and this seems to shrink it. I am very happy with my purchase, thank you
Portia –
Excellent service and the ingredients are good too according to research I did on the individual ones. My dog enjoys one a day as a treat after her dinner. This product is not the only approach I use but I can say she’s doing very well after a dire prognosis from the vet some months ago, and it seems to me that this product is contributing to her still being able to enjoy life and keep to her usual routines. I am very grateful for it.
