Hi Schiplab,
It may also help if she juggles his normal day to day routine a little - perhaps changing the times he is exercised and putting in an extra walk. Suggest also offering him his meals at a different time and also make the meals a slightly smaller quantity and with something unusual added for a few days - for eg. tinned sardines, cottage cheese or add a little warm chicken broth.
HTH, please keep us posted. Regards, Teri :)
