Query: Pet Naturals of Vermont Hip and Joint Extra Strength for Dogs Chicken Liver -- 120 Chewables

I’ve been giving these to my two dogs for 2-3 years now. One of my dogs has hip dysplasia and had great pain until I started giving her Glucosamine. I’ve used Glucosamine with my dogs for years. The nice thing about this formula is its liver flavored-which the dogs like-and it’s fairly inexpensive compared to some brands I’ve seen. The dog with the hip problem does very well with this and I plan to keep buying it.
