I have an 18 month old named Silva who was orginally on Iams from the breeder, I switched her over to California natural b/c of another local breeder recommendation she has been on the herring and recently on the chicken, Lately she has been having digestion issues (diarrhea) I also read that with better food there is less shedding and less tear stains, which she does have slightly. I also have been checking out the site and noticed alot of members give salmom oil and pumpkin. I am certainly confused. What food and treats are recommended (I do live in Canada so not sure if some foods would be available here) and also treats?? Any input or opinions would be appreciated!! Thanks in advance!
