Both of my dog's are dead...
This was before I read about dog food, they were always on Science Diet from day we got them, Misty however was on Purina when she was a puppy. They both had really bad health from the start.
Misty had a rare weird blood disease at age of 9-10 her life was a rocky start to begin with she had a illness called non-genetic blood cell disease which you can read more here

When Misty started to get ill I rush on internet and did so much research it was beyond what I found that I had imagine!
We put Misty on pedigree and I didn't like the results at all, then tried Newman's Own then we decided to home-cook prepared her meals throughout her life. She had to be on meds and we had to rotate cooking and kibble. Then we finally stick with Canidae all other source of kibble like Innova, Cali Natural, Eagle Pack were just impossible to find
And Lacey however died of spleen cancer results of that she was on science diet and was living off of table scape she died at age of 12.5 yrs old
I went here to compare to other food with Natura food as well
