Wow.... pretty interesting! I also believe "bad" dog = bad pet parent.
snip...
the misplaced guilt that comes with having a much-loved dog who is also severely aggressive or fearful of everything can be crushing.
Putting our Sparky down, due to severe behavior issues... was absolutely crushing. I'll never know if it was human error or genetics that caused her behavior. Either way, it totally SUCKS when you can't "fix" them.
Miss ya Sparky girl! (Nov was 3 years)
