So my dog has major teeth issues...2 cracked molars and maybe a dead front fang. She's only 7. I give her Nylabones and raw marrow beef bones. The dental vet said Nylabones are too hard for teeth. It's common in Labs I guess cuz they are chewers and have a high pain tolerance. Wanted to share to save some an expensive vet bill. Lookin down the barrel of $1200.
