Lifesaver for Kennel Cough!
This stuff works great, and even my picky dogs love the flavor! We initially bought when our labs contracted kennel cough from daycare, and it cut their recovery times to just a few days vs. over a week! Now, we keep by their food bins and give before and after they’ll be going to stay at doggy daycare. So easy to use – just squeeze the dropper to fill and again to dispense. We put directly in our dogs’ mouths or on their food.

Very good general supplement
I have been giving this supplement to my Great Dane with a heart condition for over a year, so I have gone through several bottles of it. It seems to be a very good general antioxidant supplement. As a matter of context, this supplement has been just one part of a regime of medications and supplements for my dog, so I cannot speak about its effectiveness if given on its own, which is why I only gave 4 stars. But I have liked it enough to continue to give it and my dog has shown significant improvement over the last year on the protocol she’s on, of which this is a part. The appearance of the product has been consistent throughout the year, which makes me believe the quality is also consistent. One thing to note – this is a standard size capsule, NOT a chewable tablet as it says on the bottle in the one picture (must be an old picture because the bottle that I have does not say this). Overall, I’m happy with the components of this supplement and intend to continue to give it.

It’s Working!
We have a pretty anxious kitty with feline herpes (viral rhinitis or the “kitty flu” if you will), and have had a hard time getting his sneezing under control. With a full dose of lysine he was still sneezing (though not nearly as bad).I’d had about enough of it and his vet had not worried adding anything to his medication. I figured being really safe and just another amino acid, DMG was worth a try.Well, he’s been on it for about a week or two (only 0.25mgs as we wanted to start slow since the vet wasn’t consulted) and the sneezing has finally subsided!We’re only using it while the illness is showing symptoms till we can discuss its use with his vet so I can’t speak to its ability to keep the virus from remitting, just that it helped get rid of his symptoms (finally!!!).I am overjoyed that this worked as I was cautious to try other remedies on the market (like Echinacea) since they can have serious side effects (and being an amino acid (building blocks of protein), this medicine is very safe).Edit: We have been using this product for several years now. It is a mainstay in his treatment for FHV/FVR.I would like to stress that this is NOT a cure, but it makes a big difference (certainly more than lysine).When we first started using this product we were already using lysine with very little improvement. DMG was a game changer! We went from regular sneezing, runny nose, poor appetite, and recurrent bacterial infections that had to be treated with antibiotics to stop unending sneezing fits… to needing antibiotics once a year when something happens to stress my kitty out enough that it compounds the chronic viral infection and he gets a secondary infection. He has made it some years totally free of sneezing and we can get him to accept a larger variety of foods (though the downside is he’s interested in human food now, lol! gotta remember to not put garlic on my chicken).His vet is even impressed with the improvement that this product has made in keeping the sneeze attacks away. It ABSOLUTELY reduces relapses and could potentially lead to medication-induced remission (my kitty’s longest run thus far is two years, through two moves!)!I would absolutely recommend this product to anyone who has a cat with FHV/FVR!And for those who don’t: My cat has always been indoor only, but I tend to pet any cat I see… and I carried this virus into my house on my clothes. This is entirely preventable. Get your cats vaccinated! Even your indoor-only cats!

Dont get scratched up by a scabby cat
This stuff is amazing! I have a calico cat who is 11 years old and has a lot of white on her. Like very fair complected humans, cats that are mostly white are prone to suffering from dry skin. Dry skin is many times the root cause for excessive iching which leaves cats raw and sometimes bleeding. Damaged skin is very prone to allergic reactions and secondary infections. Simply put, dry skin can be simply hell on a cat.This poor cat had so many raw spots on her back, from the tip of her nose to the base of her tail, that they were visable at a distance when she walked through the room. They also covered both shoulders and she had so damaged one spot between her ears that it formed an abcess. I took her to my vet who had previously prescribed the below listed drip meds which id been adninistering for several years. Non of the other cats had this problem and I noticed that the condition got worse during the winter. She was convinced that the cat must be crawling with bugs. She searched and took skin samples but found no trace of them.I treat my cats with flea drip and worming drip that I buy from my vet and apply monthly. I continued spraying kitty hysrocortizone on her which gave her only temporary relief and made her very hard to catch but at least it did something. I switched to a Burts Bees product which worked better and I was less concerned when she licked part of it off. The problem was that for it to be effective, i had to apply it almost daily. She looked like a wet mop most of the time. She loved when I rubbed the spray in but she started to only come out when she was hungry.Then I read the reviews on these Vetriscience drops. I was unable to rate the taste because she was now so shy that she ran away when I approached her while she was eating. I tried squirting them in her mouth but she never recieved the full doseage. She usually started scratching and then got away.You may be thinking, “Why bother with that cat!?” You wouldnt believe it from the way shes been acting but she used to be the most friendly and affectionate cat on the farm. I found her abandoned as a very young kitten and we have always been close friends. I was just starting to get used to being scratched up when she started approaching me again. I had been treating her with Vetriscience drops for about 2 weeks but she was getting only 25% of the recommended doses. I examined her back. There was clearly at least a 50% improvement in the condition of her skin!I was pretty sick of the scratches, wished she could get the full dose, get well and give ME a chance to heal. I was putting the meds away and noticed a tube of Cat Lax which is administered by smearing the dosage on the top of the cats front foot. If she was licking herself all the time, why not just squirt the meds on her back?It has been almost 14 days and she is nearly all healed. So am i for that matter. I highly recommend trying Vetriscience drops on your cat to treat skin irritations or allergies. There are only a few meds I keep on hand and restock before Im out. This one has just earned an honored spot on that shelf!

This product really helped boost my two cats immune system. They both have the herpes virus which they pass back and forth to one another so I treat both of them at the same time with the Mmg liquid. I also decided to take the Dmg myself in capsule form for my immune system. I highly recommend this product from this seller ***super fast delivery***

My dog’s mood improved a lot after he started these supplements. He seemed to become a lot happier and less cranky. He was recently diagnosed with Sudden Acquired Retinal Degeneration Syndrome (SARDS) and I was told them these supplements can help protect the retina while the dog is treated with other medications to try to stabilize hormones. I doubt he will recover his vision but as long as he returns to being a happy boy, I’m happy.

I have started giving them every other day. Normally if I hear a sneeze, immediately gave some, thankfully next day back to normal. I don’t know what taste like both cats have no problem with it. One likes licking whist the other I give directly.Recently I bought similar name claiming the label has been changedBought this first time 2020/2022/3Than the new one claiming it’s been certified & it’s my cat that’s reacting badly to it. It started to froth in the mouthI wish this seller will come back soonM desperately need this tonic for my sensitive flat face 1 yr 4 mths oldManage to stop his cold a few times with this than I ran out of the originalThe other seller insisted they’re got certificates etc
Amazon Customer –
This is really good and highly recommended by some of the best Vets in the world. But if should be priced approximately and not at the present rate. This price is just not workable.

I ordered this to build my dog’s immune as he had kennel cough. Excellent stuff and has no taste so my dog has no problem taking it. I am a big fan of VetriScience products and so far, I love all of the ones I have tried for my dog.. I normally order this line from my vet but seeing it on Amazon made it easier this time to order.Decomposure Pro is another favourite of mine from VetriScience,
