ומשלוח מנות איש לרעהו
A person should give mishlo'ach manot each person to his friend. They say that a dog is "man's best friend". Well, my dog, Charvonah, is really my best friend. He's very faithful! (and gorgeous, too, I should add. Know any dogs that need a shidduch??) Can I fulfill the mitzvah of mishloach manot by giving him 2 dog biscuits?
BTW - the biscuits are ראוי לאכילת כלב
