I came across this article recently that talks about "Blackie" a 19 year old dog that is doing well in a shelter in New London, ON Canada. The main topic of the article is that more dogs are living into their later teens more often than any time in the past.
The author mainly attributes the phenomenon of dogs being fed better diets than they ever have been in the past. I'm curious to hear what you're all feeding your senior dogs and if you either adhere to a raw diet or have tried one.
I switched to a no grain diet with Rusty, who I had previously had on a common dog food's senior diet formula. He's a pretty healthy guy already, so it's hard to tell if there were any short term effects, but I'm hopeful that the change will go a bit easier on his digestive system in later years.
