Shiny Coats
April 10, 2020
Recommended by my Vet as more effective than other oral joint supplements for my 12 year old pointer's hip problems.
Cannot tell for sure if joint issues are improved in Hannah but the coats on Hannah (12) and Dutchie (9) have never been so glossy.
These pups have been very active hunting dogs and constant companions. They are spoiled and are fed a very nutritious diet. To see their coats sheen-up in two weeks after starting them on Welactin tells me it is good for my best buddies.

Merchant Response:The quality supplements are usually pricy. We do what we can to pass the savings. Glad to hear that Wellactin is working for Hannah and Dutchie.
  • Glossy coats and hoping it supports aging joint health.
  • Expensive but so are other joint supplements that my vet says are mostly destroyed in the stomach before a chance for absorption.

I originally put my dog on Wellactin to help with a partially torn cruciate ligament, but it is also helping to keep the itchies at bay. My Golden often has an allergic reaction at various times on her belly, but so far it has not returned!

Welactin with Natural Omega-3 Supplement
July 19, 2016
I mix this supplement with my dog's dry dog food at her dinner time. This product keeps her coat shinny and her skin moist. And she loves it so much that she continues to lick her bowl when she is done eating!

Looks good.
July 5, 2016
I Just started giving my dog this product and he seems to like it. Omega 3 is supposed to be good for his coat and his health. I will know more as I continue using this product, but my guess is that it's going to be an excellent product and like us humans, we all need Omega 3 to maintain good health. You should try it as well.

Started using Welactin with my two boyz that has passed away 2 years, and the other a year ago. Although they were older, I could see the difference in their coats. When I look at their pictures today, I still can see how handsome they were although 17 years at the time of their passing.

Great value
July 14, 2015
My dog has issues with her skin and joints. She has been taking this for a few months and it seems to be helping. Skin is definitely better and she seems to be moving a bit better. This price is great compared as to what they charge for it at the vets.

Will continue to purchase Welactin. It seemed to stop the flaky skin my dog had.

Thank you.

I notice a difference in my dogs scratching. I believe it's due to this product helping her spring allergies along with a raw diet.

Recommended by a surgeon at the U of MN
April 27, 2015
My puppy Sam had OCD surgery on both shoulders at the U of MN small pet hospital. The surgeon recommended that we give him 1 1/2 tsp. of Welactin everyday. He loves the taste on his food. His breath smells a little fishy, but it's a great Omega supplement.
By Izzy
Perfect supplement for my dogs
April 9, 2015
I'd been searching for an omega-3 supplement for my 3 dogs that I could add to their food without causing an aversion to the "fishy" taste. Welactin is perfect. It's an easy application and they eat every bite. I highly recommend this product.

Welactin is a must for a shiny coat
February 17, 2015
My vet originally recommended Welactin for my black lab mix puppy who was having some skin issues. We have been giving him this oil every night for 4 months. His coat is beautiful and he loves the taste--gobbles his food. This product costs 50% more at my vet so I'll be buying it here from here on out.

I use this to help with my Lab's arthritis. His vet suggested the dosage based on weight. I think it helps him, plus his coat is shinny.

beautiful coat
August 30, 2014
This "vet recommended" product Welactin has been going into his food for about two years. I know it does other things beyond a beautiful coat..which is what he has. I am glad this is part of Winston's wellness program. ((( / )))

I have an 11 year old lab with hip dysplasia and knee injury. this has made a huge difference in his comfort and pain. I was told by my vet to double the dose and split it between his 2 meals each day We are on bottle number 9 now and noticed a difference after 2 weeks.

Welactin for dogs
July 25, 2014
So far my dog likes it on his food, however, it's yet to make a difference in his hair filling in, I'm still waiting. It was recommended for his black skin disease for this pomeranian that has lost some hair on his hinds legs and lower body and neck.

Welactin natural omega-3 supplement
July 22, 2014
I buy this omega-3 for my yellow lab and she loves it. I just put a little in her dry food and it seems to help with her shedding and also helps with her constipation. I would highly recommend welactin omega-3.

Great product
July 14, 2014
I've been using Omega 3s on my dogs for years. I fine Welactin to be one of the best and easy to use. Comes with a spoon so you can measure and pour so you aren't dealing with cutting into fish capsules. My dogs coat is night and day from using it and I live in a dry climate.

Great Purchase!
May 29, 2014
This product was originally recommended by my Vet for my dog's dry skin. I bought it there and then found that it was much less expensive at Luckily it is an over-the-counter item.
This is also good for my dog's heart, kidneys, brain, joints, and immune system, so even better!
She does not mind me putting it on her breakfast kibble, and it does help make her coat nice and shiny too! Her skin is still dry at times, but this definitely helps!
Thank you EntirelyPets for carrying it and at such a reasonable price as well!
By poodles r.
great product. great price.
April 29, 2014
Our vet recommended Welactin as a source of high dose Omega3. Our standard poodle has elevated ALT values which sometimes can be reduced with antinflammatory supplements such as Omega 3. His ALT values have gone down, although still not within normal limits. We will continue giving him the Welactin and hope for ongoing improvement :-)
By Kate
Easy to use - my pet likes it!

Welactin has been a help in keeping my dog's arthritis in check. It also helps keep her coat in good condition. It is easy to use and she likes it.

The only fish oil I'll use
February 25, 2014
This product was recommended to me by a veterinary eye specialist when one of my dogs was suffering from a degenerative retinal disease. Although it couldn't stop the progression of the disease, we do believe it slowed it. I've been giving this to all my subsequent dogs and have received numerous compliments on the condition of their coats and just their overall condition.

Very disappointed. Opened the bottle, and the product was rancid. This is the 2nd time this has happened to me with this company, so unfortunately, I won't be ordering from them again. What a shame....they have such good prices, but I'm tired of literally throwing money in the trash!
By clumberpaw
Good for coats
January 23, 2014
I've used this for many years, all our dogs have liked it and I'm hoping it does all the good things fish oil is supposed to do. We now have two spaniels that we bath every other a week and they do have beautiful coats.
