My 6 month old lab puppy is 65 lbs and my vet thinks she’s too big for her age and recommended I take her off puppy food and go to a low calorie diet adult food instead. I always thought it was best to keep Large breeds on puppy food through the first year. What are your thoughts? I have had her on Orijen Large breed puppy food and it seems to be a bit too rich for her as she’s been having loose stools. My vet also thinks it’s making her ‘thicker.’
