When I was a new
Doggie Chef I boiled a big beef bone for about a minute (to "sanitize" it) and gave it to Gracie to chew on. She immediately cracked a tooth. Cooked bones really are bad for dogs!
The vet fixed Gracie's tooth but advised against feeding her anymore bones, cooked or raw.
So how could I provide Gracie with extra calcium? Getting enough calcium, and the right calcium-to-phosphorus ratio, is crucial to a dog's health. Even well-intentioned
Doggie Chefs can get it wrong and accidentally harm their pets!
Every argument against homemade dog food mentions this calcium-to-phosphorus ratio. It almost scared me away from becoming a
Doggie Chef. How could I ever get it right? It sounded way too complicated.
Well, it's actually easy!
I learned to supplement Gracie's homemade meals with bone meal powder (made for human consumption).
However, bone meal powder contains both calcium
and phosphorus. It's important to find a bone meal powder with the recommended calcium-to-phosphorus ratio (or as close as you can get).
The ideal ratio most experts recommend for a dog's diet is a little more calcium than phosphorus.
Specifically: a ratio of 1.2 to 1.4 parts calcium: to 1 part phosphorus.
Yet some bone meal powders contain twice as much calcium as phosphorus!
That's okay because even though it's not ideal, a range of 1 to 2 parts calcium: to 1 part phosphorus is considered acceptable by many experts.
Through the years I've used Now Bone Meal Powder and
KAL Bone Meal Powder. Both are tested for heavy metals and other contaminants.
When using Now Bone Meal Powder I supplement Gracie’s meals with about 1/8 teaspoon, three times a week. One teaspoon of the Now Bone Meal Powder I've used contains 1,000 milligrams of calcium and 500 milligrams of phosphorus; or a 2:1 ratio of calcium to phosphorus.
When using
KAL Bone Meal Powder I supplement Gracie's meals with about 1/16 teaspoon, three times a week. One teaspoon of the
KAL Bone Meal Powder I've used contains 1,620 milligrams of calcium and 540 milligrams of phosphorus; or a 3:1 ratio of calcium to phosphorus. It's a higher calcium-to-phosphorus ratio than experts recommend but at times it's been the only bone meal powder I could get. When using it, I do my best to balance out the extra calcium with phosphorus-rich foods.
