Murph is on JWB Turkey and Rice and has been for the last year. For all he is 2 years old he is still on their Junior diet as he needs the extra calories as he a very lean dog. I also add Nature diet on top and he is doing well and holding his weight quite nicely.
Before JWB I had him on Arden Grange Performance and Prestige but he didn't gain any weight, so I tried him on Barking Heads both the Lamb variety and then the chicken but they made him have quite sloppy poos.
