    Cosequin® DS (Double Strength) is rated 4.7 out of 5 by 173.
    Rated 5 out of 5 by from Works great!!! Had a decent effect on my extremely arthritic 8yr old Lab and was able to cut her from 4 Dermamax a day down to 2. The biggest change was our 10yr old Corgi who had never showed any signs but I gave him some to see if it would make a difference. To my great surprise, he was so excited for dinner one evening that he actually jumped over the sleeping Lab to get to his bowl! I haven't seen him jump that high since he was two!

    Rated 4 out of 5 by from good product I have a Corgi with back leg lameness and Cosequin DS has really helped. Rarely does she limp.
    Date published: 2011-03-03
    Rated 5 out of 5 by from It works I had tried a few other supplements on our 3 year old mix. He started limping when he would get up from laying down. It hasn't even been a month and I'm already seeing a difference. I can't wait for our vet to see the change.

    Rated 5 out of 5 by from Excellent product Both my 9 1/2 yr old yellow lab and my 7 1/2 yr old black lab are on this product. I can honestly say that it has definitley helped their mobility, reduced pain and stiffness--they're having fun again. Black lab used to have extreme difficulty getting up from her bed after a good exercise and now she's jumping, leaping and hopping around as if she were years younger. The yellow lab has had shoulder problems plus an ACL surgery. These pills have helped her tremendously with the added plus of being able to cut back on her antiflammatory/pain prescription meds. I highly recommend this to anyone who has a companion with mobility difficulties! Have had no problems with either one of them being able to tolerate the pills but I always give the pill with food.

    Rated 5 out of 5 by from Perky Boxer at 12 years old My Boxer is 12 and this product is helping to keep him perky! I give several supplements in addition to this one so it is hard to know for sure which is having the greatest impact. My guy gets this, CortaFlex, Fish Oil, Adequan, Traumeel and Ligaplex. My vet is a big believer in the supplements listed above and says that they work well together.

    Rated 5 out of 5 by from Remarkable Difference I have been using Cosequin DS for my elder dogs ever since my 10 year old Corgi had knee replacement surgery several years ago. He recovered so well on it and he needs to be on it the rest of his life. I also put my 14 year old Corgi on it to head off any joint problems that may come his way. Both my Corgis are still active and they eat the tablet with no problem at all. It is the best joint supplement made for dogs! The only downside is the cost it should be made more affordable so everyone can use it.

    Rated 5 out of 5 by from Just The Right Thing! My great dane is 8+ years old and although he doesn't have major issues, we wanted to prevent something from happening. It seems to be working well, he tolerates the med quite nicely. We use Cosequin for the horses and I would not be without it!

    Rated 5 out of 5 by from in love Cosequin has really given my 6 yro Golden his mobility back. Before taking Cosequin 4 years ago Lucky could one walk .5 miles without becoming lame do to hip dysplasia now he can easily walk 3 miles without any lameness. I highly recommend it to anyone who has a breed prone to hip issues

    Rated 5 out of 5 by from HUGE CHANGE I HAVE 2 very active jack russell terriers, one is VERY long legged and big for the breed, she has a tremendous amount of energy like all jacks and can jump 5 feet with ease..she started having soreness from her rough play and after several visits to the vets with no problems found on xrays or other tests we put her on this product, she is so much happier and not lame anymore...i now feed it to her 1 yo brother he is very small but active as well they are both doing great on it...

    Rated 5 out of 5 by from Great product, our dog has been using it for almost 6 months as a preventative measure. No issues yet! I was slightly disappointed in the canine smartpak though. I was under the impression that the pills were going to be put directly into the food packets, but they were in their own little baggie. Next month I will just go back to buying the big bottle.

    Rated 5 out of 5 by from Good stuff can see a real difference in mobility since using the product, not a cure of course, but definitely a big help

    Rated 5 out of 5 by from Dogs Love Them My dogs think these are treats so they are obviously tasty to them - and they come running for them when it's time for them each day. We have 3 large breed dogs - 2 Goldens and 1 Lab - and 2 out of the three are on the Cosequin DS now. This is the best product that I've found on the market and I would definitely recommend it to anyone who has a dog with dysplasia.

    Rated 5 out of 5 by from WONDERFUL joint supplement My 7 y/o German Shepherd occasionally limps after a long day at the barn. I have been giving him 2 pills/day for about 7 months and he's doing excellent! The best thing about these pills is that they're chewable and he LOVES them! He's picky when it comes to pills, so I was worried I would have to push them down his throat, but I don't have to!! :)

    Rated 5 out of 5 by from Great Product This product was recommended to me by a friend who has a dog with some joint problems. My dog is 12 years old and has had ACL surgery on both hind legs. She still has a lot of vitality. She moves easier and seems less stiff. It is also easy to administer the chewable tablets. I just put them in with her food.

    Rated 5 out of 5 by from Excellent Medication I have an 11 yr old Sheltie, who has just developed arthritis in her left front leg. She was really starting to limp, but since I started her on Cosequin double strength, the limp has gone away. She is walking and running just fine. Thank you so much.Mystic Blue

    Rated 5 out of 5 by from It Works I've used every kind of joint supplement for my elderly golden retriever with mixed results. I decided to give this one a try and I'm glad I did. Nothing at first but after several weeks on the product, his mobility has definitely increased. I have no problem with him eating the tablets either. I'd recommend you give this a try if your dog is facing serious joint problems.

    Rated 4 out of 5 by from Great Product Both my dog and horse receive Cosequin. It's the only joint supplement with the research to back it up. It works great and being involved in both the veterinary and competitive horse (hunter/jumper) world, I've heard nothing but great things about it. I will continue to use this product throughout my animals' lives. Compared to some other joint supplements it may seem a bit more pricey, but I really believe that I'm getting what I'm paying for!
