I have Gus on JWB Lamb and Rice and he is doing well on it for over a year now.

As he is less active now and can have a tendency to put on weight (but is not overweight now) his food is quite reduced compared to the other two 'nuts' (Pippin and DJ)...

He will be 8 years old in a couple of weeks so I was wondering, should I put him on to a senior food?
