Whаt wаs thе оnе thing yоu didn't knоw whеn yоu gоt yоur first dоg?

I didn't know that dogs have breaking points when it comes to the issue of anger just like us humans. I also learnt that their anger is tempered, they underreact. Dogs take offence if you pull their tale or unduly interfere when they are having a meal. I remember accidentally stepping on my dog. It let out a loud wail. I expected a painful bite but it only placed its teeth lightly on my leg. What a wonderful restraint!
