  • Two Easy Ways to Start Earning Rewards!

My 10-month puppy eats less but is active. Is it time for adult food?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 10 months and 12 days old | 78 lbs

Our 10 month old puppy has changed his eating habits from three times a day to maybe once a day. He is still very playful and bounds of energy. Weight seems to be maintained at 75 lbs. Is it time to slowly change his food to regular dog food? Only concerned because he was a chow hound to only eats in the evenings. It seem to start after his visit to the ER for a bee sting and benedryl. But that was several weeks ago. Still loves treats. Any suggestions would be great.

If Teddy is still acting completely normal, eating his regular amount and maintaining his weight, I wouldn't worry too much. Some dogs will prefer to only eat once a day and do just fine. The 9 to 12 month range is when I normally recommend transitioning to an adult food, so you could start doing that and see if he wants to eat once or twice a day. If he starts losing weight, doesn't have the energy he used to have, or develops vomiting or diarrhea, I would be concerned there is something more serious going on and would have him examined by your veterinarian.

    If Guido is eating less but seems to be maintaining his weight and is otherwise acting normal it may be that he doesn’t need as many calories as you are offering. If he is losing weight or if you notice any soft stool, diarrhea, vomiting or other symptoms you should see your vet for a physical exam. I typically don’t recommend switching to adult food until a year of age.
