I was recommended to buy this food by my vet after my large labradoodle was getting recurrent ear infections and itchy skin, as she said food intolerances can cause both. We haven't had an ear infection since, but the coolest thing is that his poops are now smaller, denser, easier to scoop up, and much MUCH less smelly. That is, if I'm honest, almost a bigger selling point than the healthy ears for me! I never realised what a difference a high quality food can make. And he seems to really like the big chunky kibble bits. Expensive, but worth it for me -- especially if you buy more cheaply online.
