Absolutely swear by this stuff. I was having my dog to the vets every other week due to her yelping every time she moved. They would just put her on painkillers and anti inflammatories and send her home. Been using this for around 4 months now and she hasn’t been yelping or back to vets since!!! Started giving it to my other dog as well as she is getting on at 11 years old and she is like a puppy again can’t recommend this product enough and the weight she has lost since due to being more mobile is incredible.
