What is Vetri-DMG?

Vetri-DMG is a liquid supplement that strengthens your pet's immune system. It has many other benefits that make it easier for your dog or cat to stay active and free from viruses and other dangerous foreign 'invaders'. Vetri-DMG is strongly recommended by veterinarians for pets with chronic illnesses including seizures, infections, diabetes, endocrine issues, heart problems, feline leukemia, allergies, asthma, and arthritis.


Cats and Dogs

  • Supports your pet's immune system in order to fight off viruses, bacteria, and other foreign microorganisms
  • Helps your pet's body cope with stresses
  • Helps your pet stay active by enhancing circulation and muscle recovery
  • Supports glucose metabolism which is helpful for diabetic pets
  • Aids in cardiovascular health which is great for pets with heart disease
  • Promotes antioxidant activity in the body
  • Helps with liver detoxification
  • Reduces lactic acid buildup which is very helpful for working or active dogs
  • No known side effects
How it Works:

Vetri-DMG is administered on a daily basis (twice a day for the first two weeks). DMG is a water-soluble nutrient produced naturally in both humans and animals that helps the body use nutrients efficiently at the cellular level. DMG has been proven in clinical studies to increase antibodies which helps keep your pet free from viral and bacterial infections. As a bonus, it also helps support stamina and circulation, so your pet can be happy, healthy, and active.


If your pet is pregnant or may possibly be used for breeding, consult your veterinarian before using Vetri-DMG.

Customer Reviews
Vetri-DMG is rated 4.7 out of 5 by 22.
Rated 5 out of 5 by from love this product Usually when the vet recommends a supplement, I use it but usually don't see any need to continue it later. This was suggested for a kitten with upper respiratory problems. It really helps him a lot. I've been giving it to him for a year now. He stays very active and alert. He loves to take this "medicine"--begs for it. I've been very impressed. I plan to keep giving it to him.

Rated 5 out of 5 by from Boosted immune system, brought her back to life About 6 months ago, my cat, who has feline leukemia, stopped eating, was constantly vomiting, sleeping, and cringed whenever I touched her. She would still come in and sleep on me, but had no energy and whimpered a lot. When I found out that she had leukemia, the vet led me to believe I could make her as comfortable as best I could, or look into euthanizing her. I spent hours searching online for possible medicines that I could give her, even considering some pretty ridiculous and potentially stupid cure options. I found this and used it in conjunction with a Pedialyte and baby food mixture fed to her with syringe. Within 2 weeks, she was eating dry food again, running around with the other cats, and even more energetic than she'd been in the months leading up to this crisis. I still give her a small dose each day of Vetri-DMG, and I think the cost is a small price to pay for having my cat healthy and happy.

Rated 5 out of 5 by from This product really works! My cat had a severe allergic reaction to Tidy Cats Lightweight Kitty Litter. He had runny eyes, a runny nose with congestion, and was sneezing and coughing. Once I discovered the problem, I stopped using this litter, and ordered HomeoPet Nose Drops for him. This helped his coughing and sneezing within a few days. Then I saw Beanie's review that mentioned combining HomePet Nose Drips with Vetri-DMG. So then I continued giving him the HomePet drops 3 times a day, and added the Vetri-DMG dose once per day as described. This combination worked wonders! Now his eyes look so much better, his nose drips less, and his sneezing and coughing have practically stopped altogether. This is the immune boost my little boy needed. Thank you to Beanie and 1-800-Petmeds!

Rated 5 out of 5 by from Great product I have a short hair domestic cat who has suffered from upper respiratory infections for three years. No one could seem to tell me why she was getting them. Since trying this product (along with the HomeoPet Nose Relief), she rarely even has a runny nose any more and she is much more active -- she is 17 1/2 years old and is acting like a kitten again! She is also diabetic and there has been no interaction problems with her insulin. I found it took a few weeks for it to get in her system but once it did, the results were wonderful. Thanks so much for this product!

Rated 5 out of 5 by from Saved my cat's life My kitty is almost 6 now. She is an orange tabby. After her first vaccination, she got a big itchy sore on her neck and head and was diagnosed as having eosinophilia. She was put on steroids and after a year she appeared to be getting headaches and then had several seizures. We finally went homeopathic and topical steroid to keep the itchy sores in remission, and found the vetri-dmg which I have been giving her for 4-5 years for possible seizures. Last month I decreased the dosage of the vetri-dmg to almost nothing thinking she may not need it anymore and she had a seizure. I put her back on the vetri-dmg and she has not had one since. The product is wonderful. It is nice to know it really works. Being on phenobarbital and steroids is no life for a cat. I am so happy she can live a normal life because she is so sweet and has been through so much.

Rated 2 out of 5 by from Quantity too small I gave this fair as it has only been 2 weeks before I ran out -- I have a GSD! At the dosage for a large dog, the amount is ridiculously small. At over $13, I will look else where...

Rated 5 out of 5 by from A High Paw from Lady Ghost Our cat, Lady Ghost, Whispurr, asked me to write this on her behalf. She was diagnosed with diabetes about a year ago and we could not afford to treat her with insulin. Other than upgrading her food, we are trying to keep her as comfortable as possible. I saw the advertisement for Vetri-DMG and decided to try it. Lady Ghost absolutely loves it! She will come and ask for it every night.and lick it right off of the dropper. I don't know if it just tastes that good or if somehow she knows it help her feel better. It hasn't cured her diabetes but she can still jump up in the window to get some sun, eats well, and purrs when we pet her. I believe it has allowed her to keep a good quality of life longer than if she didn't get it. Just ordered some more per her request.

Rated 1 out of 5 by from Made my pets condition worse My pet cat has allergy's he has been to a vet & they gave him a shot that seemed to help but it didn't last long his symptoms returned fast My poor cat is constantly inching biting & scratching his eyes are red & irritated, he is eight years old & has suffered with allergy's through most of his life, I have tried other more expensive products but I simply can't afford to keep paying the expenses for my kitty that is why I opted to try Vetri-DMG I researched & also read other reviews & thought this product might at least offer some relief to my long suffering cat Long story short I fallowed the directions & my cat would eat the product fairly easily, but after two weeks I noticed his eyes became more red & he seemed confused & aggressive, the product did nothing to help my cat so I stopped administering it as soon as I realized that he was getting worse. I would not recommend this product unless you have had previously positive experiences with it because you risk harming your pet, it is not worth the risk.

Is this something that you need to give them for the rest of the animals life? Or just temporarily?

Would it be okay to dilute the DMG with water? My bird would need ½ a drop, which would be impossible to give but I figure if I do a 50/50 dilution then I can give her one drop of the mixture and it would be the proper amount of DMG. 

Asked by: BKnight
DMG is a water soluble nutrient. This product may be less effective if diluted. You may want to consult with your veterinarian to see if it is okay to dilute this product for your furry baby.

How does one administer the drops? Can the drops go in dry dog food?

My cockapoo is 33 lbs. Per the dosage guidelines, he is supposed to get 1ml per day. However the instructions read 2x daily for the first 2 weeks. Do I give 2ml per day or split the 1ml between 2 meals, which would be .5 ml 2x a day.
Asked by: Les
Thank you for your question. It is suggested to give the medication directly into your pet's mouth because it is such a small amount of medication. However, you can mix it with food but it is suggested to do a small amount of food to ensure that they eat the entire amount. The amount given is based on the weight of your furry pal and it is best to split it half in the morning and half in the evening.

rosemary extract in dmg (for cats)

should i be concerned about the rosemary extract that is used in DMG for my cats. I don't want to give them something for their overall health if it is just going to cause problems later on in their lives.
Asked by: ilamc20
Thank you for your question. This product does not have any known side effects and it is perfectly fine for you to adminster to your furry pal.
