I'd say that high proteins is good are general. It's usually better way for a dog, because higher protein = lower carbohydrates. So as for physical health, I wouldn't be concerned, BUT you have a point w/ dogs being full of energy. If you're not actively doing any sport or walking daily for at least 2-3 hours, I'd say high protein diets are a bit "pointless". You'll see after switching back to TOTW 
It might be just that Acana doesn't suit your dog in general. Maybe EVO or other food w/ higher protein would be ok. This choosing kibble is worse than science 
good luck w/ your doggie
