Does anyone have any experience with this brand? I've been giving Bentley Orijen since he was two months old (he's 10 months old now) he does good on it but I notice he drinks and pees a lot, and his pee is too yellow. I was wondering if it's too much protein for him? It's 42% protein so I decided to change to grain-free Acana, which is 32% protein. He's currently loving Acana, he's eating the acana kibbles and leaving orijen kibbles on the side lol ....
Am I doing the right thing?

(I was thinking about waiting a month or two and see if he doesnt get as thirsty with Acana or if his pee stops being so yellow)
