1/31/17 Before you toss eggshells out with the trash check out two recipes for mak­ing  min­er­al rich cal­ci­um.
Dog Nutri­tion­al Cal­ci­um Sup­ple­ment Secret #1: Rinse and air dry egg shells. Place on a cook­ie sheet in a 325 degree oven and bake for 10 min­utes.  Grind the baked shells to a fine pow­der using a clean cof­fee grinder or blender.  Store in a clean, dry air-tight con­tain­er. Eggshell pow­der will last indef­i­nite­ly if kept dry. Dose: 1,000 mg cal­ci­um per 1,000 kcal/ME (metab­o­liz­able ener­gy). Con­sult with your vet­eri­nar­i­an for the prop­er dosage.

I feed a fresh, var­ied and cleaned diet to my dog.  I com­bine fresh pro­tein with veg­eta­bles, fruits and some grains.I  buy organ­ic ingre­di­ents free from hor­mones and NonG­MOs. A fresh raw meat diet in par­tic­u­lar requires a cal­ci­um sup­ple­ment. Dogs need a lot of cal­ci­um to sup­port the body’s skele­ton, teeth, and brain func­tion.

Oth­er sources of cal­ci­um include goat milk, bananas, dark leafy greens, and sea veg­eta­bles (nori, kom­bu, waka­mi). BTW  I don’t use bone meal pow­der sup­ple­ment because they can be con­t­a­m­i­nat­ed with heavy met­als, such as lead and alu­minum.

Toma­to-Grow­ing Secret #2:  Air-dry egg shells, crush fine, and mix into the soil around the roots.  Shells will turn bone-dry in just a day.  Add a dozen crushed egg shells to each plant­i­ng hole.

How does your gar­den grow? Long wet spells, long dry spells, and/or alter­nat­ing drought and flood can cause the fruits to go bad on the bot­tom. Eggshells add cal­ci­um to the soil and help avoid blos­som-end rot. Now watch your beau­ti­ful toma­toes ripen.
