How much calcium is too much for a Labrador Retriever? Many sources say over 1.3 is too high. The food I feed my puppy is 1.72 is that okay or will he develope issues?

Hello, and thank you for your question! As a large breed dog, the ideal calcium to phosphorus ratio should be 1.1 to 1.3. So your current food is not ideal but it is definitely not too late to switch! Look for a puppy formula for large breed dogs. Good brands that have this formula include Science Diet, and Royal Canin. Keeping him on a large breed puppy formula until he is at least 1 year of age will help to prevent hip issues as he gets older. I hope this helps, and that Louie is happy and healthy!

Yes. The goal for large breed puppies is a calcium under 1.5% AND a calcium to phosphorous ratio of about 1:1 (some say up to 1:3). As of this year, dog foods will be required to state whether they have met these rules in their AAFCO statement (see link below). In general, most of the reputable pet food brands who label their food as a "large breed puppy food" are following these rules. http://vetnutrition.tufts.edu/2017/02/confused-about-what-to-feed-your-large-breed-puppy-new-rules-may-help/ Hope this helps and best of luck to your big boy Louie!

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Raider is quite the handsome dog! Especially for large breed dogs, it is OK to feed them a puppy food until they are 12-16 months old, as long as they are still active enough to not become overweight. Puppy food tends to be higher in calories than food formulated for adults. You can certainly stick with TOTW for his adult food, as long as it says on the bag that it is formulated for adult maintenance. To answer your question about the ideal calcium:phosphorus ratio- for dogs, the ideal ratio of Ca:Phos in dog food is between 1:1 and 2:1. I hope this is helpful!
