Does anyone have any information on the best source of calcium for dogs?
Over the last few years I have been feeding a mix of kibble for breakfast and the honest kitchen with added meats/veggies for dinner.
Both my dogs, who are seniors, had low blood calcium when they had their spring check-up and that made me think it might be related to their diet.
When I did a search for tricalcium phosphate, I didn't get too much information but some negative comments about how it is a cheap ingredients, basically bone ash and used as an anti-caking agent in some processed food. This is the calcium source in the honest kitchen which is a fairly expensive dehydrated food. The kibble I feed has calcium pantothenate so I wondered if that was a better source? I don't really know.
I have started to add crushed eggshell which is essentially calcium carbonate.
Does anyone know which source is best absorbed by dogs?
