I gave them to Joey, before I understood the problems with them, and he ate a whole package with no ill effects, I don't know what the safety margin is, it may be 1 out of 10,000 dogs, have problems, but if yours is the unlucky dog, the results can be disastrous, and how do you prove, that it was the greenie? So the ones we hear about with problems, probably had a vet take a sample of the obstruction, and had it analyzed. Most vets probably don't even do that. |
