the Shulchan Arukh doesn’t mention any particular restrictions on having pets.(3) And the sages of the Talmud and the Talmudic era continue to acknowledge the unique connection that exists between an animal and its owner. In one place, the Talmud acknowledges the unique canine characteristic of loyalty to the master. (4) Elsewhere, we learn that animals can absorb the sensitivity to holiness displayed by a righteous master. For example, we learn that the donkey of the renowned saint Rabbi Pinchas ben Yair refused to eat untithed produce, leading the Talmud to comment “the Holy One blessed by He doesn’t make the animal of a righteous person an [ethical] obstacle.” The Midrash tells of a cow that became accustomed to resting on Shabbat and refused to work on that day even after being sold to a non-Jew, until its former owner gently explained that the new master was not obligated to provide a day of rest.
At the end of the day, like everything else Some will say it’s fine others it’s not ideal. To clearly say it’s wrong is actually not true. True there are some considerations with Halacha, but if educated they are easy to work with. If you have a dog you know how gentle and loving they could be. They’re silliness provides smiles to the whole family. Children form a wonderful bond with them and they are very theraputic especially for the elderly who are often alone. Fot those of you who don’t have one that is fine, but to say it’s a sin is completly wrong and not founded on Halacha.
