Maximum protein I will consider is 24% mine are in the 22%-24% range and yes i do believe it is detremental to any dog unless it is a field/working/hunting dog during the time it is actively working. Once they are done their work which is seasonal, back to a lower protein diet.
I do believe, over time, a steady high protein diet will cause irreversible problems which I have seen too many times.
i also have seen for myself and believe a high protein diet will affect behaviour making them hyper or as a very old time breeder friend of mine coined the phrase, 'running on their toes' which describes it well.
That is just my opinion, you can decide as you wish for yourself. |
