  • My dog refused to take turkey tail mixed with food. I worry that this will not be accepted either. How often does that happen?

    Thank you for your question! We haven't had any returns due to palatability issues since this product was released. Since this mushroom supplement is a soft chew, it may be more palatable than capsules, tablets, or powders. However, it's possible some dogs may not eat the product. We offer a 100% guarantee on all PET | TAO products. You can view our refund policy here in case your dog doesn't enjoy the soft chews.

  • My dog has mast cell tumors. If used as directed, how long before improvement is seen? Also, she is currently taking prednisone; is it safe to take both?

    Thank you for your question! All supplements take a few weeks to start working in your pet's body. No supplement has been tested to cure a condition, but the mushrooms in Complement Immune such as reishi have been shown to have anti-tumor effects. It is safe to take Complement Immune along with other medicines. Learn more here:

  • Will this help neutropenia

    Thank you for your question! Results may vary depending on the type of Neutropenia. Our vets think Complement Immune may help raise the amount of circulating WBCs in your pet's blood. To learn more about Complement Immune, check out these blog posts:

  • Why are there no reviews on this product?

    Thank you for your question! We are working on some new technology that will ask customers after each purchase to leave a review. We haven't implemented that yet, so there are no reminders going to our current customers asking for reviews. Also, many of our customers purchase through vet clinics or stores, and not through our site, which has left the product pages lacking in reviews. It is something we're continually trying to improve and work on!

  • Have you thought about removing the rosemary? Rosemary is a seizure trigger for dogs w/seizures. I would LOVE to give this product a try - it has great ingredients - but can't take the chance of lowering Jesse's seizure threshold. So disappointing...:-)

    Thank you for your question! PET | TAO's veterinarians believe the amount of rosemary in Complement Immune isn't high enough to lower a pet's seizure threshold. We do recommend showing Complement Immune's product label and ingredient list to your veterinarian to see if they approve of its use in your pet. Thank you for your interest in Chinese Medicine and the powerful mushrooms in PET | TAO's Complement Immune!

  • PET | TAO Complement Immune Supplement - I have a 9 yr old with allergies and 2 mast cell tumors low 2 in 4 months. I feed nutritionists prescribed home-cooked diet and supplement with multi vitamin copper, Choline, omega 3, Calcium carbonate and Phosphate, Quercetin and Canine System Saver. I see the Vitamin A – 1,050 IU, Is this too much Vitamin A considering he is already receiving A in his multivitamin? I am interested in the combination of mushrooms but feel the added vitamins may be too much considering he is already receiving them in his multi.

    Thank you for your question! I'm sorry to hear your dog is struggling with allergies and mast cell tumors, what a tough combination. Complement Immune is a supplement that can support both of these conditions in dogs and cats. According to the Merck Veterinary Manual, the Vitamin A requirement for dogs is 3,333 IU/kg of diet fed, with up to 333,300 IU/kg of diet considered to be safe. So, even a small (2lb dog) could get up to 333,300 IU and it would be considered safe. If you'd like to double check, I'd recommend checking out your vet's opinion of Complement Immune to see if they think it would be safe in conjunction with the other great food therapy techniques you're using.

  • Hello, Do you have a UK website please, this is where i live and would like to place an order. Thank you.

    Thank you for your question! You can email us at with your address and we will look into whether the UK allows import of Eastern herbals and our other products.

  • My dog has been recently diagnosed with Cushing's disease. He produces to many steroids & has begun the medication, Vetoryl 60 mg. capsules daily. Will be re-evaluated in 30 days. We did talk about supplements (pre and pro biotics and something for joint health) & diet, however, have not made any decisions since its only been 3 days. He is 8 yrs. old. Which of these supplements do you recommend we begin him on?

    Thanks for your question! If your vet recommends a probiotic and joint supplement, check out PET | TAO Harmonize GI and PET | TAO Harmonize Joint. From a TCVM perspective, dogs with Cushing's are often supported by an energetically cooling diet. Check out PET | TAO Chill and see what you think! We also carry Eastern herbs to support dogs with Cushing's. Check with your vet to see if any of these fit your dog's situation - then, request authorization here:

  • What is the dosage? I have 2 large Shepherds. I also am seeing many dogs being diagnosed with many aggressive cancers. I’m love heard great things about these mushrooms and am hoping to utilize them as a proactive measure a long with their current home cooked human grade diet.

    Thanks for your question! 
    For dogs that are 51-100 pounds, give 2 soft chews twice daily. For dogs that are over 100 pounds, give 3 soft chews twice daily. This supplement is a great complement to food therapy and herbs.
