Is it okay for my 15-month-old large dog to finish puppy food?

Growing puppies have specific nutritional requirements that differ from adult dogs, particularly with respect to their calcium and phosphorus balance, and an overall increased calorie demand. Vitamin and mineral deficiencies for a growing puppy can result in a variety of problems, so as a result, a puppy should not eat adult dog food on a regular basis. An occasional bite from their older housemate’s bowl should not pose any problems, but stick with puppy food as their dietary staple.

Ideally, growing dogs should be fed puppy food as their nutritional needs are different, especially for minerals such as calcium. Energy demands and protein levels are generally higher for growing dogs so as long as she has not become significantly overweight or has any lameness/joint pain this diet would be unlikely to have any side effects!

The young puppy should be on puppy food in order to provide the balanced nutrition she requires for healthy growth and development, a large breed puppy food is recommended for optimal joint health. It is not ideal for adult dogs to be on puppy food as they may continue to 'grow' and become overwieght so you will have to monitor very closely if he has access to puppy food that he does not become obese

Yes, puppy food is a "hotter" diet higher in protein and carbs. It is formulated for a growing puppy that needs the extra nutrition. An adult dog may gain excessive weight if fed a puppy formula regularly. The higher protein content may also put undue stress on the older dog's kidneys. If possible, feed then separately or take up the puppy food if you free feed.

That should be OK for one bag. If possible after this bag I would go back to a puppy food for another month or two months depending on how large your puppy is. Some labs will continue to grow for 12 to 18 months of age others plateau around 10 to 12 months. If there's any doubt if your puppy us on the growing stage you can ask your veterinarian.

It's fine to feed Gizmo the large breed puppy food since it's designed for puppies (which should be fed up until one year of age). The large breed part just refers to the size of the dog. I hope this helps!

Yes that is perfectly ok. They are both balanced dog foods. Just check the bag to see how many calories per cup so you can adjust as needed (meaning if more calories in the puppy food you will have to feed a little more adult food or vice versa). I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
