What is Duralactin?

Duralactin is a nutritional aid for dogs and cats that contains a patented dried milk protein concentrate that is believed to help manage inflammatory conditions long term, and possibly diminish the need for steroids or NSAIDs. Duralactin Canine is available as a chewable vanilla-flavored tablet, and Duralactin Feline is a non-flavored capsule.


Dogs and Cats

How it Works:

Duralactin contains MicroLactin, a patented dried milk protein from the milk of hyperimmunized cows. MicroLactin contains factors that appear to block and inhibit body chemicals from participating in the inflammatory response.


Some cats may be sensitive to milk proteins and/or carbohydrates. If vomiting or diarrhea occurs, discontinue the use of Duralactin and contact your veterinarian.

Customer Reviews
Duralactin is rated 5.0 out of 5 by 20.
Rated 5 out of 5 by from Fantastic!!! I have a 10 year old Chocolate Lab. She has always been a bundle of energy. In the last year she has slowed down considerably due to arthritis. She has arthritis in her paws, ankles, hips, and back. She has a permanent limp because of limited range of motion in one of her paws. It was a struggle for her to get up from a lying position. This product seems to have shaved a few years off her life! She can stand up without a problem. She seems to have more energy. I'm so thankful my vet recommended this product instead of the much more expensive NSAIDS!

Rated 5 out of 5 by from Wow..... Just Wow My 11 year old yorkie developed arthritis in her back knees. She started limping and her entire demeanor changed. I took her to the vet and got her on Rimadyl. It seemed to help very little and after 10 days the vet reported the swelling was still quite severe. I was devastated. I searched 1800petmeds and decided to try Duralactin, Synovi G3 and Yucca Intensive. It has only been 12 days, but I kept thinking she seems better. I started to question whether I was seeing what I wanted or was there real improvement? This morning after she used the potty she ran across the yard to me. I could hardly believe it. Yes, she is still limping (slightly), but she is getting much better, She really does seem more herself and I can tell she is in less pain. I want to thank everyone who took the time to review this product and recommend the other two products as well. My hope is to be able to stop the Rimadyl soon. She gets one half pill twice a day, one Synovi G3 small bite and 2-4 drops Yucca Intensive per day. I mix the Yucca with pumpkin and she cannot detect it. I am THRILLED with the results I am seeing.

Rated 5 out of 5 by from The best supplement we've tried! My 12 year old lab/mutt mix tore her ACL five years ago chasing a squirrel and had surgery. She has been on Rimadyl, Tramadol, and Cosquin since then. Then last year, she chased a squirrel again and tore her other ACL. Our vet didn't recommend surgery with her age (and the first surgery was difficult to endure/she cried in pain for days even with strong meds) and said she may recover some mobility with time. In addition, because of the ACL issues she was putting most of her weight on her front paws. In the past few years the front paws have turned inward and it appears that her tendons have torn (the vet told me the long name for the injury and said that in a younger dog, he'd recommend surgery). She walks slowly and appears to be in pain since her front paws have spread out and turn inward. For the past year, she has spent about 95% of her time in our downstairs family room so she doesn't have to walk up a flight of 10 carpeted stairs to the main living area and she only comes up when it rains. I have tried a few additional supplements over the years, but none have helped / have caused diarrhea. I order Rimadyl from 1800petmeds, so I decided to check if there is anything to help with her walking/pain. I read the reviews on Duralactin and decided to try it. At first, she did not want to eat it, so I put it in her food with some water and wet dog food so it will taste better. Well, within 5 days she was coming up the stairs a couple of times a day! She is back to laying in the front window and waiting for her food in the kitchen at each meal. She has now been on it for three weeks and is doing great! It is unbelievable that she is coming up the stairs every day! I am so glad I decided to try this---after trying so many supplements that didn't work. I still give her Rimadyl, Tramadol, Cosequin, & Omega-3 fish oil in addition to Duralactin :) and she is looking out the front window now!

Rated 5 out of 5 by from Helps with skin allergies, too Used this on my Cocker Spaniel who had food allergies in addition to arthritis and other 'old age' conditions. We changed her food and that helped with the constant scratching. But she still scratched. Once we added Duralactin to her regimen the scratching stopped completely and she had better mobility. Great product!

Rated 5 out of 5 by from It Works with Synovi G3 Sophie, a 10 year old 45 lb blue heeler has had trouble with her knees for the past 3 years. I tried numerous brands of medication until I started to give her one tablet with her morning meal. At dinner, she gets a Synovi G3 tablet. This combination Works! She now runs and jumps like a young dog.

Rated 5 out of 5 by from works well Started using this product about a week ago and am already seeing marked improvement in my dog. He is quite old and has been very lame. He is moving much better, having a much easier time getting up off the floor to stand. I am actually thrilled and surprised at the difference I am seeing.

Rated 5 out of 5 by from Amazing results!! I have a 7 year old male Rottweiler. He is average size, right around 100lbs. He started limping a little about a year ago, even though I've had him on Glucosamine/Chondroitin supplements since he was 2 yrs old (recommended by our vet.) He would hesitate a little when sitting down, and then limp for the first few steps after getting up. After a week on Duralactin twice a day, he no longer limps at all, and acts like a puppy! For his weight, the bottle said to give 1.5 tabs twice a day, but I decided to try just 1 tab twice a day, and that has done the trick. Thank you so much for giving my dog his youth back!!!

Rated 5 out of 5 by from Excellent My dogs story is just like most the other reviews on here. Chihuahua that would suddenly slow down, hide, and whimper in pain when touched. I would give her a half a baby asprin just to get rid of the pain long enough to get her to eat the Duralactin. After 3 days I think it was, she was off to the races! :) SHE THANKS YOU VERY MUCH!

Increased appetite

My cat is 17 years old. Since I started him on Duralactin, he has been eating like a horse :-) Is this a side effect of the medication?
Asked by: Crissy
Please consult with your veterinarian. The increased appetite is not a documented side effect of the supplement and could be a result of changes in your cat's metabolism that your veterinarian may want to evaluate.

Still effective if dog won't chew?

My dog won't chew this. She spits it out but I put it in a piece of cheese she swallows it. My question is, is it still effective if not chewed up because it makes a difference in some medicines.
Asked by: Northernbreedlover
no, it will still be effective if swallowed in the cheese

Can I give my cat the entire capsule? Is it digestable? She won't eat anything sprinkled on her food but easily takes pills.

Asked by: Debby
Thank you for your question. It has been recommended by the manufacturer you twist open the capsule and mix the ingredients with your cat's food.

Is this products safe to give with or immediately after stopping Tramadol?

Asked by: Ginger
You would definitely want to speak with your vet about this product to ensure that it will not counteract with Tramadol and if you can use it once the Tramadol has been removed from your pet's daily routine.
