If you look at the stats you are more likely to get bitten off a border collie than any other dog, but because they are not used as fighting dogs/guard dogs/police dogs no one cares.
A dog is only as viscious as its owner lets it.
We had Max in to get xrays on his hips the other day, sedated aswell, which I wasnt there for, when I picked him up I asked if he had went for any of the vets/nurses the vet told me this
"yeah he turned to bite me and just mouthed me, I found it quite pathetic" I took it as a compliment as I have seen Max chew through marrow bones/ribs/turkey legs like they were nothing.
