I don't know about a definitive answer, but I never feed my dogs puppy food. As soon as I've gotten them I begin the switch to adult food. I just don't want to encourage fast growth and the problems associated with that.
Interesting I just checked that out and turns out if your vet said that, well Timberwolf Organics Black Forest has more Calcium 1.2% and phosphorus 0.9% vs what Jesse was on before the switch which was Science Diet Large Breed Puppy Calcium 1.10% and phosphorus .86%. Also I understand a GSD puppy needs low crude protein Timberwolf Organics Black Forest is 22% Vs. Science Diet at 26% - just a little of my research done. But yes lots of different opinions, and every dog is different. Side note: Jesse is right on schedule in weight and size to the charts too.Originally Posted By: LucinaMy vet told me to keep Lucy on the large breed puppy for now. She's six months and is not growing too fast- very lean, right on the chart where she should be....but he said they need the extra calcium and phosphorus for their growing bones still.
So no, there evidently is no definitive answer but lots of different opinions. I think as long as they are getting what they need and growing properly there are several right answers.
