Chondro Flex II is a joint support supplement formulated specifically for dogs and cats. It is designed to promote joint health and mobility, and it can be particularly beneficial for pets with arthritis, joint pain, or those at risk of developing joint issues due to age or breed.

Key Benefits:

  1. Joint Support: Chondro Flex II contains a blend of ingredients that provide comprehensive support for joint health. It includes glucosamine, chondroitin sulfate, and MSM (methylsulfonylmethane), which are known to promote the production of cartilage, support joint lubrication, and maintain joint flexibility.
  2. Joint Comfort: Chondro Flex also includes ingredients like MSM (Methylsulfonylmethane) and hyaluronic acid, which have beneificial properties. They can help reduce joint discomfort and promote a more comfortable range of motion in dogs and cats.
  3. Pain Relief: Pets suffering from joint conditions often experience discomfort and pain. Chondro Flex II helps alleviate joint pain and inflammation, allowing your dog or cat to move more comfortably and freely. It can help improve their overall quality of life by reducing pain associated with conditions like arthritis.
  4. Enhanced Mobility: By supporting joint health and reducing inflammation, Chondro Flex II can improve your pet's mobility and range of motion. This is especially beneficial for older pets or those with joint-related mobility issues, as it allows them to engage in physical activities more easily and maintain an active lifestyle.
  5. Cartilage Protection: Chondro Flex II contains antioxidants that help protect and maintain the integrity of cartilage. It assists in preserving the cushioning properties of the joints, which can slow down the progression of degenerative joint diseases and protect against further damage.
  6. Easy to Administer: Chondro Flex II is often available in the form of chewable tablets or soft chews, making it convenient to administer to your pets. Many dogs and cats enjoy the taste, which simplifies the process of giving them their daily dose.

It's important to note that while Chondro Flex II can provide significant benefits for joint health in dogs and cats, it is always advisable to consult with your veterinarian before starting any new supplements or treatments for your pet, especially if they have pre-existing health conditions or are taking other medications. Your vet can provide personalized recommendations based on your pet's specific needs.

Proprietary Blend of Ingredients:

Chondro Flex is a powerful joint care formula that provides maximum nutritional support for dogs and cats with a predisposition to degenerative joint disorders. Chondro Flex contains the highest quality Glucosamine, Chondroitin, MSM, Ester-C?, and chelated minerals to effectively reduce inflammation and support the maintenance and repair process of connective tissue.

Active Ingredients:

Glucosamine and Chondroitin help keep joints and connective tissues resilient, lubricated, and mobile. Chondroitin is also necessary for healthy cartilage as it absorbs water to keep the cartilage hydrated and cushioned.

Anti-Inflammatory Agents & Antioxidants:

Chondro Flex contains MSM, an organic form of sulfur. Healthy connective tissues and cartilage contain proteins with flexible sulfur bonds. Once the sulfur combines with glucosamine and chondroitin, they form collagen, a substance that gives cartilage its structure and flexibility. Antioxidants also play a significant role in the overall health of your pet and its joints. Vitamin C helps heal and construct cartilage to keep your pets mobile and happy.

Excellent Supplement
January 9, 2017
I was buying these from the vet's office and found them at a more reasonable price thru Entirely Pets. We have a 10 1/2 year old Great Dane who takes 2 of these daily with great results. His old legs are still shaky, but he is doing well and does not need any other medications.

I have used ChondroflexII on my present dog with hip dysplhagia and and have recommended this to others with same results as it really calms down and SLOWS down arthritic changes. There are OTC and other products, but this is the one for me. .
Maggie Loves it
October 23, 2016
It crushes so easy with a spoon. Sprinkles over her food. A Maggie is not limping now. More energy. About to finish the 2 for eight weeks. Older dogs with arthritis need it!

nice pricing
November 23, 2015
I first was given a script from my vet for my fur-baby and was paying around $60 and kept going back. After multiple purchases; I looked online for the same thing and I was shocked to find it at a lesser price. It is the exact same thing but it does take a full week to get to you.

I don't know if the product is making a difference but if my vet says to use it--then I do.

Murphy thinks these are treats, he gets one every night when he goes to bed and beats me upstairs. He knows I have his tablet in my pocket.

Great price and fast service! This product has kept our Lucy going for several years. She's 16 now and can still act like a puppy when playing.

I think it helped

I bought this for our 8 year old German Shepherd who has problems with his weak elbows. In the recent years this has become a real problem, we could see how hard it was for him to get up or to jump or cross even low obstacles (like stairs). Since we've been adding this supplement, things improved. Visibly! It's obvious his pain is lesser, he has more energy and is more playful. It took some time for the supplements to start working (we've started seeing results after approximately 3 months), but they sure do work!

Chondro-Flex II = Great Stuff!
April 14, 2014
I've been using Chondro-Flex for 18 yrs and it really does an awesome job.

My Male JRT was 15 when I lost him and just as limber as when he was 5. He took it daily for 10 yrs.

My Female JRT is 13 and she acts like a pup. She will always be on it.

There are other products out there, but my Vet recommended Chondro-Flex and I have stuck with it.

I would rate this as #1 in Joint Supplements.

My dog Zoey was born with arthritis in her front paws. She is now going to be 12 years old. She had "knee replacement" due to an injury last year and has some trouble with that but her arthritis has pretty much stayed in check. I also use it for my other dog who is 10--have had her on it since we adopted her at 2 years old. I will be putting my youngest baby on it as well-- she's not yet 2 years old.

All the chewable tablets in this size bottle remained whole, all the way to the bottom of the bottle, unlike the larger bottle. Although it costs a little more in the long run to buy in smaller quantities, you are less likely to find the bottom tablets broken into tiny bits or turned into powder.

Will never go anywhere else for the products I purchase for my wonderful dog Max. Purchasing this product here, I was able to order 2 bottles for less then the price I paid for one bottle at my Vets office.

Wish I knew they were expired before I purchased
November 24, 2012
I should have know something was up when the price was so much lower than normal so I shouldn't have been surprised that the product was expired when received. Be careful what you order.

Review for Chondro FLEX II (120 Chewable Tablets)
November 4, 2012
I like the ease of giving your product to my dog and My dog really likes the taste of the chewables, but what I would like to see is an expiration date of the product when ordering so I do not order to many and they expire before they are gone.

Good stuff!
October 23, 2012
I've had my 11 yr old Dogs on this product since they were 2 yrs old ( just for precautionary measure ) and they both still run and jump like they are pups! So glad I started my girls on this product early in life! ;-)

Good, but not Great
August 15, 2012
I decided to try these for my dog because it said they were chewable and he would not chew the other chewable joint supplements I bought him. I would have to put them in some food or in a treat even though they are allegedly chewable. When I got these the first thing I noticed is that they are virtually impossible to break in half even thought they are perforated. My dog still will not chew them, so they have to go in some food again. He takes double strength joint supplements 2x a day and triple strength if he needs a little extra help on certain days. I think these are doing a good job and they are a great price, but wish he would chew them and most importantly, I wish they were easier to break!

I have purchased a product similar to this that my dog would take but she absolutely loves these. She eats these before she eats her dog food.

I've used this product for about a year and love it. I have two performance dogs that do agility and it helps them. I also have an older dog (12 yo) and she is still very active.

Great Product
February 15, 2012
Chondro Flex II works great for my older cats as their joints were stiffening up and I can see the difference in their mobility. They even tear through the house occasionally like they used to when they were younger (and they will be 15 yrs. old this year).

Purchase this for my "elderly" puppy. She still thinks she is a puppy, but her legs think otherwise. You can really tell a difference when she misses a dose or two. Thank you

My 12 year old spaniel mix was having a lot of joint pain that actually caused him to yelp when he jumped down from a chair. He was also limping frequently and was very stiff. This product has made him much more comfortable. He still has his stiffness, but does not limp as often and does not yelp with pain. It is not an instant cure, but over several months I can see a definite difference.
