Food & NutritionCan I keep feeding my dog Hill's a/d prescription diet long-term?
Prescription diet A/D is high in calories so it may not be the most suitable diet for long term. You have to monitor Coco's weight to determine when this food needs to be discontinued. Also it isn't necessarily a puppy food, so it's best to go back to his normal large breed puppy diet primarily and then if you want to mix in just a few tablespoons of the A/D to keep him interested, that may be completely fine until he reaches sexual maturity and no longer has high calorie food demands, which is typically around 8-12 months of age in large breed dogs. I hope this helps!
