Our Jake is almost 13 years old. He is a Doberman and their normal life expectancy is 10-12 years. Jake has arthritis and is very weak in his hind end. He often falls over so he doesn’t move much. Mostly sleeps. After giving him a few days worth of the Canna treats I noticed he seemed to be around more. After just 3 boxes he is up and running, begging at the table like the old Jake we knew and loved. He seems much happier and he will continue getting these treats for as long as he is with us.
