I also hate Petco. Aren't they the store that killed a s**tzu by overheating it with the dryer. I know there was another story similar to that, but it was the one where the dog was litteraly baked, but this one was a bit less dramatic, but the dog still died.
Anyway, I have Petco becasue my Greyhound Rescue group used to do Meet and Greets there. The groomers would come by and clip their nails for us for free. I had on Grey who had really long nails and he had a really long quick as well so we had to clip his nails on a weekly basis. Well this dip shi* started cutting and cut the nails really short, deep into the quick. The poor baby started yelping and crying and I told the groomer that the dog couldn't have very much cut off of the nail, and I explained the dogs issue. The groomer said he knew, but he was "quicking" the nail for me. He said that it doesn't hurt the dog and if you keep cutting the nail into the quick everytime you trim the nail the quick will eventually get shorter

What and IDIOT. Of course it hurt that poor baby. Why the fuc& is the baby screaming and crying if it didn't hurt.
Luckily I caught him after 2 nails. I told him to get his hands off of the dog and if he so much as petted her I would break his fingers I was SOOOOOO Mad!
