George Leo Haydock, on Tob 6:1

“And Tobias went forward, and the dog followed him, and he lodged the first night by the river of Tigris.”

“Dog. Greek and Hebrew specify this circumstance, (chap. v. 22.) but not here. Those who attack the authority of this book, infer that such a trifle would not be noticed by the Holy Spirit, chap. xi. 9. Yet Homer mentions the fawning of the dog upon Ulysses, after he had been 20 years from home; and the gravest historians record instances of the fidelity of dogs. (Calmet) — Night, or stage, mansione, (Haydock) at a caravansera, or house where travellers might stop all night, and sometimes, though seldom, might be supplied with necessaries. Herodotus (v. 52.) mentions several in the kingdom of Persia. (Calmet)”
