Growth spurts don’t come from protein level. There is an old myth going around that won’t die, because ignorant breeders perpetuate it, that high protein causes too fast growth in large breed dogs. This has been disproven. Period. The real culprits are overfeeding and too much calcium. This has been proven. Period. I’m relatively positive that one of the links that Hound Dog Mom provided on the first page of this thread was to the study summary where these facts were proven. However, you can google it for yourself, just google “calcium levels for large breed puppies” and you will get a few different studies about it. If you want to go at it from the other direction, google “protein levels for large breed puppies.” Try looking for actual science rather than some breeders opinion though, there are definitely articles supporting every opinion under the sun. If in your research, you find that Hound Dog Mom is right, then by all means share what you have learned with your breeder. She needs more current info.
