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." Strongly recommended by veterinarians for pets with chronic illnesses including seizures, infections, diabetes, endocrine issues, heart problems, feline leukemia, allergies, asthma, and arthritis.

Vetri-DMG is rated 4.65 out of 5 by 20.
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.

Rated 5 out of 5 by from No More Allergies! I don't normally write reviews, but this product has impressed me so much and made such a difference with my two pets (12yrs old and 9months old) that I had to share my experience. We moved to a new house and my dogs had some allergy problems with something outside.... One was diagnosed with rhinitis and the other just had bad conjunctivitis. I wrote to the petmed pharmacy and they suggested DMG. I used it and BOTH of my pets cleared up within 2 weeks!...and the bonus for me has been watching my grumpy 12yr old chichi act like a happy 6yr old...She is jumping around again!!..:) This is a great product and I recommend to anyone who has pets as a good daily vitamin for their dogs to be at their best!!..

Rated 5 out of 5 by from Energy booster I have a 13yr old Bombay cat who is about 18#! He's a little bit of a chunky monkey, but not too bad for his breed. He has a baby sister who is a Bangel mix and she keeps him on his toes! This product is great! It has put a pep in his step, and he now is back to chasing lizards and chasing the baby every now and then! He's more interactive, plays more and his coat is super soft!!

My dog in on Phenobarbital and Pottasium Bromide, she is diagnosed with idiopatic epilepsy, can I give her Vetri-DMG?

Asked by: Magaly
The Vetri-DMG has no known side effects. However, you may want to consult with your vet to see if it is safe to give this to your furry baby along with the phenobarbital and potassium bromide.

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.

Can I give this to my FeLV cat along with the VitaChews for cats?

Snappy has feline leukemia and is 5 lbs, about 4-5 years old. I want to know if I can give her both the Vetri-DMG liquid and the VitaChews for Cats. Would that be too much for her? Or is that the best thing to do? Thank you!!!
Asked by: Rosie
Hi Rosie, have you "asked the vet" on this site about your cats situation? He is Dr. Dym and he's been treating my cat for well over a year now. He is an excellent natural homeopathic vet and he recommended Vetri-DMG liquid to her about a year ago and she has been taking it ever since. I would recommend you ask him as well as your regular vet. God Bless! Rachel
