17 יז

אלא הא דתני רב יוסף ארמלתא לא תרבי כלבא ולא תשרי בר בי רב באושפיזא בשלמא בר בי רב צניע לה אלא כלבא כיון דמסריך בה מירתתא אמרי כיון דכי שדיא ליה אומצא מסריך בתרה אמרי אינשי משום אומצא דשדיא ליה הוא דמסריך

The Gemara asks: But this seems to contradict the baraita that Rav Yosef teaches: A widow may not raise a dog, due to suspicion that she may engage in bestiality, and she may not allow a student of Torah to dwell as a lodger in her home. Granted, it makes sense that it is prohibited for her to have a student of Torah lodging in her home, as he is regarded as discreet in her eyes. But concerning a dog, since it would follow her around afterward if she would engage in bestiality with it, she is afraid to sin with it. Therefore, it should be permitted for her to raise it. The Sages say in response: Since it will also follow her around if she throws it a piece of meat [umtza], people will say: It is following her due to the meat she threw to it, and they will not suspect her of sinning. Consequently, she will not be deterred from transgressing.
