Spidy said it ALL!
It makes me furious to see such a picture

Some dogs should be put down… BEFORE an injury happens!!!
There are no excuses for bites. If the best training doesn’t work, there is no other choice but a one way trip to the vet…NO matter how “sweet”

the dog is.
I curse the day the dog (and any animal for that matter) became ONLY a pet and people got so emotional involved, so they... in the name of LOVE for the dog... justify ALL lack of respect for other people's life and health.
