When I started providing the GNC pet vitamins to my dog, I noticed positive changes within a week. Firstly, my Collie started eating more food and became more playful. Secondly, the coat became softer. Highly recommended for all dog owners.
In case you want your dog’s immune system to be strong, you have to provide the GNC multivitamins for dogs. My canine likes eating them, so I experience no issues with providing them twice a day to my buddy! Five stars!
