I swear by Repashy ICB which is a calcium/vitamin duster for live food. I haven't EVER had calcium issues in my cresteds or chahouas, no tail kinks, no nothing just healthy little breeders. I feed all breeders live once a week and no one else gets live food because it isn't necessary, but dusting with this stuff is golden in my opinion. Just don't overfeed live a ome like to do these guys aren't insectivors and need the CGD to be the main staple. Good luck pippy snouts are soooo cute it will have you truely addicted, which is a great thing, lol!
