Things like this is what irritates me. I take mine to Lowe's, Home Depot, and several other places. This is the first I've heard about Lowe's. I don't know the story behind the dog biting incident, but I can just about guarantee that it comes down to stupidity, whether it was on the owner's part or the person that was bit. I say this, because after 15yrs of animal rescue work and dealing with dogs ranging from the tiny Yorkie and Chihuahua all the way up to Dobermans, GSDs, and even Wolf Hybrids, 95% of dog bites occur due to downright poor judgement, which I prefer to call stupidity, because in my area...well, that's what it comes down to. Some people I would gladly say that it was just uneducated on the dangers, but most just don't care to even try to control their dogs or, on the other side, don't care to watch the warning signs. Don't get me wrong...I'm all about trying to educate and about helping people, but when you get no where more times than you get through...it gets a little frustrating. On another note, yes, I have met fearful biting dogs, which in those cases, those dogs shouldn't be out in public in the first place.
As far as people with allergies...I have allergies to some breeds and places that are well ventilated, like Lowe's and Home Depot, even Petsmart...it doesn't bother me at all, and I know to avoid those breeds.
I wish there was a way that it could be required for the dog to pass something like the CGC before going into a public place. I don't know if that would work or not, but it would sure cut down on bites. Not saying they wouldn't happen, because I witnessed a certified therapy dog going after another one during a therapy visit one time, but that's very rare.
Anyway, that's just my two cents.
