Buster has always loved his bully sticks. He does not eat anything else hard as he never liked the antler chews or the Himalayan dog chews so bully sticks must be the culprit. I made sure to use Free Range Eco Natural Bully sticks which are free from antibiotics, steroids, harmful additives or hormones and always the thin ones. Well I have learned a hard lesson and Buster Brown is the one who has paid the greatest price. He lost the crowns on three teeth just behind his canine teeth, they were literally cracked off with the roots exposed. Buster had to have the left over parts and roots removed and the holes sutured. Plus 2 back molars had to be removed because they were loose. So Buster lost five teeth and I am out just under 1800.00 because of chewing on Bully sticks. I feel so bad that I put him through so much pain.
