Here's Sabine's views on too much protein.? From a letter where I asked her. ...
There is no such thing as "too much protein".
Case in point, the NRC publication gives a "safe upper limit" for things like fat, vitamin A, vitamin D and some
other nutrients, but there is none listed for protein. Dogs are carnivorous animals with dentition and a
digestive tract that are best suited for eating meat, fat and bone. Carbohydrates can be digested, but only if
they are fed in a usable form - which means with their plant cell walls broken down already. Hand a dog a sheaf
of grain or a sack of raw potatoes and he couldn't get much nutrition out of that. Cook them and they become
digestible. What are examples when a dog should not have too much protein. ? There are very few actually.
One thing that comes to mind immediately is a dog where kidney failure has progressed to the point where the dog
is actually uremic, generally meaning lab work shows BUN over 80 mg/dl and creatinine over 4.0 mg/dl. This is
where it actually makes sense to restrict protein to reduce the work load of the kidneys. I have attached a file
that you might find of interest in regards to protein and kidney disease - mainly because most vets still follow
long outdated information.
The other is chronic pancreatitis, because it's not only the fat content of the diet that stimulates the
pancreas, protein also does."
Deb the only thing to concern yourself with protein in the quality not quantity. Check out her link at Better dog care.
