Is he getting enough exercise? Long walks? Maybe increase the amount of walks…..
Anyway you can take him swimming? Some vet clinics offer aqua therapy (swimming in a heated pool) if you have pet insurance and your vet orders it for weight loss, it may be covered.
One minute of swimming is equal to 4 minutes of running and it’s easy on the joints.
Exercise improves mood, decreases pain (release of endorphins) and therefore reduces hunger that may be caused due to boredom or discomfort.
