HELP, HDM! My bullmastiff “puppy” is now 130 plus pounds at 15 months. When do calcium levels cease being an issue? I would like to switch him to Nature’s Variety Instinct because I had a previous rescue bullmastiff who did very well on it but I am afraid to do damage because of the calcium issue…
Thanks,
Lynn
