He will sit there and back at me and show his teeth.
The FIRST time a dog seriously threatened me or a member of my family would be it's last - I will NOT tolerate a threatening animal on my property. (Note the word "seriously" . . . a growling pit bull or Alsatian is a very different from a yappy little dog like a chihuahua or pekingese . . . )The dog was standing on MY porch Grawling at Me.
As already cited, TX law permits shooting of a dangerous dog to protect humans or other domestic animals.
