LLoyd.... I don't have to worry about someone blaming me for goofing off. I'm retired after 40 years chasing drilling rigs. I was never so accused. As far as seeing dog attacks, yup, I've seen more than my share... been handling big working dogs for a LOT of years... learned to walk hanging on to pointer collars (no real problem there)... first full-on attack I witnessed was one of the AF guard dogs going into a local national outside a bomb warehouse/dump in sunny south east asia. Dog was one of the AF GSD's that probably weighed in excess of 130lbs. About 40lbs more than the local national. More than 200 stitches but she lived. Next one came from a 'food guarder' dobie that nailed a kid. Similar results. I love... and respect... big working dogs. Lost my rottie recently to cancer and down to just one dobe at the present. I do NOT respect anyone that mistreats animals. I do NOT respect anyone that won't do their job... especially when it is to protect the public. I do NOT respect anyone who carelessly and snarkily attacks another poster for merely stating his beliefs. My biggest problem was not with the Chow... it was with the owner. I was prepared to kill the dog if it attacked but I intended to use the dead dog to discipline the owner. I will not allow someone or someTHING to attack me on my property to go unpunished. Maybe it's a flaw in my character.
