I bought this after trying another brand. The other brand worked well but only came in an 8 oz. bottle so this was cheaper and more convenient. I have a bouvier des flandres who has skin allergies so he is always scratching. This salmon oil has helped to reduce his scratching after a week. It has also made all of my dogs' coats shinier. I feed my dogs twice a day, and they eat dry kibble. I have a 23 lb mini schnauzer, 33 lb standard schnauzer, and 85 lb bouvier. I use one pump per meal for each schnauzer and four pumps per meal for the bouvier. I will probably always use this, as long as it continues to help with the skin allergies.
