My Cocker Spaniel has arthritis so bad. It was so hard for her to get around. Specially having to go up steps. I had tried several other brands then I found NaturVet Joint Health powder. She hates pills, etc. But loves this powder! No problem with her taking it mixed in her food! AND WHAT A RESPONSE! She goes up the steps without any problem, acts much younger now. I love the product. Easy to use too! I mix 1 teaspoon in her breakfast each day! So glad I found this.
