Bede, on Prov 26:17

“As he that taketh a dog by the ears, so is he that passeth by in anger, and meddleth with another man’s quarrel.”

“As he who takes a dog by the ears, etc. The Apostle says, Do not strive about words to no profit, to the ruin of the hearers (II Tim. II). Therefore, whoever is simple-minded, and if the ear of one of the two who are quarreling is captured by his biting word, he quickly begins to bark like a dog and generate contentions; but the wise man avoids this altogether.”
