A girl I know gave up her dog (which she had for years) because Rabbi Wallerstein said that Jewish people shouldn't have dogs. She didn't give me a reason that he gave as to why one is not supposed to have a dog, so I have no idea why this is so. Was it a halachic reason? Was it traditional thing back in Eastern Europe not to have a dog?
One theory a friend of mine told me, was that the Torah says man should not get too close to animals, and people tend to get really close to their dogs. But I was thinking about that reason, and it makes no sense. Firstly, in my knowledge of Leviticus (very Limited) I would think that this "halacha" or Torah statement would be in Leviticus. The thing is, is that IF it is in Leviticus the "man cannot get close to animal" line probably refers to not "being with" the animal. So I highly doubt THAT would be why you cannot have a dog. Though with all the stringency's I can definitely hear Rabbeim saying "If you're alone in your home and your dog is there with you, and you love it, you may be tempted..." I know...EWW!
The second theory I made up. Due to the parnasa "crisis" the Rebbeim felt compelled to ban "extras", which further prevent people from living decent lives. Think about it...if the rebbeim ban dogs (and cats- though they're easy to hide), the frum community has more money, and are now "bored." With this new "income" they can now gamble at Chinese auctions, and sponsor dinners and yeshivos, and perpetuate the cycle of parasitic kollel men.
Whatever the reason for this dog ban, be it sick and sexually related or just randomly a "parnassa" topic, I highly doubt this dog thing is authentic halacha. But what do I know? Did any of you ever hear of this? And if you did, can you please back up with sources anything you would say against the cute little furry creatures.
