I screwed up the other day! I recently got a puppy (yes I am allergic to dander, so I keep her really clean) and went to the pet store to buy her some toys.
I picked out these little tennis balls that were just her size. I started to play ball with her and broke out into hives. Then my throat started to get scratchy, then my eyes began to swell.
I didn't know what was going on until I read the package the balls came in. PEANUT BUTTER FLAVORED!!!!@*$#@%#%#
When I went back to the same store I started reading all the packages. Many were peanut butter flavored.
So be careful, and also watch your neighbors dog toys, you never know which are flavored.
