When I first brought home my little puppy Suzi the breeder had her on Puppy Chow. I knew that was a low quality food too. Then I thought Science Diet was better due to the fact the vet sold it and had samples in his office.
As I became a member of YT I found out Scienc diet was NOT a quality food either

SO I started doing a little research and learned about how bad the corn and other fillers were for out Babies. A wondeful lady sent me samples of Life's Abundance , and a little cookie. Suzi loved the Cookie, but did not like the food. THat was a no go for her.
Then I found A puppy Kibble that is made By Nature. This one to me looked very good and nutrious. AND they also make canned. I checked on the food list , and the kibble rated a 4. not that great, but not that poor either. However, the CAnned made by the same company scored A 6. That is the highest rating given. However the canned is expensive, but when feeding a little dog , it goes far.
I am feeding Suzi both now. She eats the canned right up , and I leave the kibble down for her all the time with fresh , bottled water. I try not to feed her the canned too much because i want her to eat her kibble too.
i DO NOT think it is bad to feed both canned and kibble . It gives variety and it is the best of both worlds.
I also give Suzi human foods such as, Yogurt, cheese, White chicken meat , rice, only in moderation, and not too often.
Best wishes to you , I know how difficult it is to find a great food for your furby.
I am curious as to if anybody has ever heard of the Kibble i am referring to? Nobody has mentioned this one before? Even though the canned has a rating of A 6.
