Is there no Chondroitin in these ?
Answer by ParkersmonOct 08, 2022
The green lipped mussel that is added would include natural Chondroitin. So yes it does include it.

13 yrs old but acts like a puppy now!

Baby is on 2 fish oil capsules. 1000 to 1200 mgs. each day. it has helped her arthritis considerably. I ran out of them for a few weeks. Then one evening as she got off the bed, I thought her back was broken and she didn’t want to be touched. Her back looked like an inverted V. It scared me so much! A neighbor gave me fish oil to immediately put her back on it. Unfortunately, I think some damage had been done and she didn’t recover as she had been before. My vet recommended these chews and for several months I thought I had wasted my hard earned money. I am on low income so I was tempted to stop. It was almost a year before I suddenly saw her in a different light. When she goes outside now she wants to run like somebody is chasing her. She plays with her little ball and wants to play fetch. She is a completely different dog! Don’t give up if you try these. It’s my understanding they need to build up in a dog’s system to start to repair the damage before you will see results. I cannot tell you how much she has changed. I am so thankful. I highly recommend these!

Metal shards in the soft chews

I give 2 stars because I normally get my orders with no issues. This particular batch of soft chew had metal shards in the bag and inside the chews itself. I put one in my hand to inspect it closer and I immediately dropped it on the counter because my fingers felt like I touched fiber glass. It's in my skin & hurts. I couldn't imagine a pet parent who didnt notice and gave it to their pet :( I just wanted to let you guys know on the case theres more of this batch people may have recieved. I recieved this order around sep 10th.

Our vet recommended these and a couple weeks into beginning them my golden retriever had way less snap crackle pop in her joints and moves so much more comfortably. Couldn't be happier and she loves eating them too

Synod G4 Soft Chews Joint Supplement for dogs

These chews have really improved Charlie's left hind leg. He has some sort of a joint problem where he hops about every 4 or 5 steps. These chews were recommended by my vet. They have really helped him.

Got this for my senior boy who was just diagnosed with osteoarthritis. He’s been taking these for about 2 weeks now, and we have been “loading”, so doubling his dosage for the first 4-6 weeks, per our vet’s advice. I have already noticed a huge change! He’s not limping nearly as much, much less whimpering when he gets out of his bed, and he jumps up to greet me when I get home from work again! I will be recommending this to all of my fellow dog parents and this will be a staple for my boy from here on out!

Been using this product for our dogs joints for a number of years, even our old girl, and she can still jump up on the bed at 11 yrs old. Thank you.

I see more energy in my dogs

My Aussie and my mix are both 8 and 9 and with these along with top quality wet/dry dog food and treats, I see more energy in them. They even roll around more than usual lol
