Small Dogs with a Big Mouth
Some of us have had Big dogs AND Small dogs so can see this issue from both angles, but i think we can all agree - some small dogs can be a little antagonistic. They have no concept of their size, and their courage far outweighs their stature, they have little weight behind them and small teeth, they are all bravado - of course this doesn't apply to the gentler breeds! My previous dogs were German Shepherds and a Rhodesian Ridgeback, the amount of times especially my Shepherds were affronted by a tiny dog, barked and lunged at was countless (one was more forgiving than the other who would snarl).
