Is there no Chondroitin in these ?

Answer by Cockers5dvmOct 08, 2022
The green lipped mussel that is added would include natural Chondroitin. So yes it does include it.

February 2025 the price of Synovi G3 had risen to $69.98 for 240 count packaged in a sturdy plastic bucket. the current Chewy price for Synovi G4 is $75.70. Not only has the Price gone up, the dosage per piece has been halved. So to get the same dosage you would have to buy two bags. Here's the math: $75.70 x 2=$151.40. $151.40-69.98=$81.42. That's more than double the 2025 price for flimsy packaged product with broken pieces. The ingredients don't appear to have been changed. Only difference between G3 and G4 is the size of the chew and the packaging. That's outrageous.

Quality Supplement - At least it was

Back when it was a Bayer product, this was the supplement my Boxer's Orthopedic Vet recommended after her TTA. She did amazing with it. (That was a few years ago)

Back when it was a Bayer product, this was the supplement my Boxer's Orthopedic Vet recommended after her TTA. She did amazing with it. (That was a few years ago) Currently is seems different, and my current dog turns her nose up to it. Even her favorite "cover up treats" to disguise it won't work. Even other dogs I know who are not picky about food at all turn their noses up at it. I gave it 3 stars because I believe it would still be a good supplement. But it's not good if you can't get a dog to eat them.

Product change is disappointing.

I have been purchasing Synovi G4 Hip and Joint chews since 2018. I am very disappointed with the new packaging and pricing of this product. This has been stated

I have been purchasing Synovi G4 Hip and Joint chews since 2018. I am very disappointed with the new packaging and pricing of this product. This has been stated from other reviewers as well. The 240 chews only last for two months now instead of 4 months with a hefty price increase as well. The chews are stuck together in a sticky mess where you have to attempt to pull off an estimated dose of the medication. I doubt I will continue to purchase or recommend this product in the future.

Reduced quality - double the price!

I purchased these for our dogs for YEARS! I was always very happy with these. For years the came in the tube and the servicing size for my dogs was 2 a day. Now

I purchased these for our dogs for YEARS! I was always very happy with these. For years the came in the tube and the servicing size for my dogs was 2 a day. Now they changed the product, sell it in a pouch, they reduced the size by 1/2 and they are gross and crumbly when they arrive. I know have to give 4 as a serving size. So, basically they cut the size in 1/2 but charge the same for the same amount and you have to double the dosage. Will find something new as this is a disgrace!

Poor Quality

I have been giving these to my dog for 6 years now and have seemed to help with his joints and mobility. Now that the product has changed packaging and dosage along

I have been giving these to my dog for 6 years now and have seemed to help with his joints and mobility. Now that the product has changed packaging and dosage along with the size of the product the quality has declined. Not to mention the price is way more than it used to be. The last bag came in one big lump with the treats stuck together and the bottom of the bag full of liquid. I will most likely be looking for a replacement for the future.

We absolutely love Chewy and this order was a great reminder of why. While we previously had a bad experience that was due to FedEx (not Chewy), we decided to give them another try because we’ve always loved their customer service, and they didn’t disappoint. This order arrived smoothly and everything was perfect. Chewy consistently goes above and beyond for their customers and pets, and we’re so glad we stuck with them. Highly recommend!

My vet recommended these

My 12 year old German Shepherd loves to fetch ball. She runs so hard that her right hip started hurting her. It was very painful and noticeable. My vet recommended

My 12 year old German Shepherd loves to fetch ball. She runs so hard that her right hip started hurting her. It was very painful and noticeable. My vet recommended giving her Synovi g4 and shortening the distance we threw her ball. And shortening her time playing by just a little. And it made a big difference. So far she still plays and no pain or limping. Love this product!!

Difficult to Separate

New packaging - a pouch - and configuration of the chews (smaller and very soft & stuck together) and dosage recommendations have brought me to the point of choosing a different brand of joint supplement next time around. The pouch packaging results in a glob of chews that are often broken up, hard to separate, and difficult to ascertain at times how much constitutes one chew.

Product quality has declined

Our dog has been on this for a number of years ever since our vet recommended it. Sadly over the past 6 -8 months it’s changed. It used to be shipped in a box

Our dog has been on this for a number of years ever since our vet recommended it. Sadly over the past 6 -8 months it’s changed. It used to be shipped in a box. The morsels were a good size and didn’t fall apart and my dog only required 1 twice a day. Now the morsels have shrunk by half and they ship into a bag which causes the morsels to stick together and more often than not they are broken apart so you don’t know if you are giving enough. Additionally the packaging now says based on my dog’s weight (which hasn’t changed) he has to have 2 morsels twice a day. And the cost of the product has increased. I no longer think it’s effective and I’ve had to switch to something else. I can’t recommend this product.

Not happy with Bayer

I have been giving my dogs Synovi G4’s for the last nine years and have been very happy with the product when it was produced by Elanco. This time however I received the “new” Bayer version and was shocked to find that I paid the same price for smaller chewable that were essentially half the dosage of the older version, basically a 100% increase in price. Not only that but they were sticky and wadded together in a big clump. I will not be buying this product again.
