I have a 6 week old puppy named Scrappy, the previous
person had him on Cesar puppy food. When I got him I bought him Cesar puppy food cause I didn't want to drastically change his food. Someone told me that when I was ready to switch from Cesar to Science Diet, to mix the portions at first so he can eat it and I did. He ate it, now that I'm ONLY giving him Science Diet he will take maybe 3 licks and back away from the food.... What should I do?
