I fed my dogs gravy coated Milk Bone treats (8 per day) for two years & both (4years old & 6 years old Labs)died in the last month of large internal tumors This was the only single cause of the problem that I can relate to their demise. My previous dog lived to 19years without Milk Bone treats. We are devastated & scared. Their food was Beneful which supposedly had no problems. Comments please!
