Typical human deflection. Blaming the family pooch for the pater familias’ poot goes back to Roman times during pre-Christian smorgasbords that involved heavy drinking and feasting and other heathen activities which probably included unsanctioned coupling as well.
The dog being a most noble and virtuous creature has borne the blame in humble silence for centuries and unable to defend itself from the malicious and arful charges must occasionally resort to fighting fire with fire. What else is a cunning canine to do, I ask you?
