I switched my dogs to Canidae All Life Stages about 1 1/2 weeks ago mainly cause of some gas issues and hair loss and I have noticed no change in either. Is there a recommended length of time before there should be a noticeable change. Also I have read other forums that state with "better" food their dogs pooped less and ate less. Mine seem ravenous all the time and they go 5 or 6 times a day. I am guessing this means I should try another brand, but I don't want to jump the gun. Any thoughts??
