Howdy all, and welcome caffaddict!
That's a whole tonne of calcium you have described. You might be able to sell the poo in your yard to schools as chalk.
(just kidding)
I did a quick google search about calcium supplmentation, and found learned postings both for and against additional supplments for large breed dogs.
My breeder also is "for" calcium supplments. She has a Great dane breeder friend who advocates this, that she reffers to as her expert. My breeder's son is also a vet. I know he tells my breeder to supplment, but not as much as she does. She also does the BARF diet, and I use premium natural HGQ (human grade quality) pet foods.
I am really confused about which 'think camp' is correct.
What are the feelings of the Rottweiler group on overboard calcium supps? I would like to know if there are any studies or papers about this availible so I can make an informed decision as well.
regards,
Monte.
