Q: We have been giving this to our two golden retriever puppies (started at 6 1/2 mos old) for almost two months now at the recommendation of our homeopathic vet. WOW - what a great product! Their coats are like satin - among all the other benefits it provides (joints, organs, skin, etc!) and they love it! The pump is great and makes it really east to add to each meal; really good price too.
A:
Positive
