Everything listed above, and add...per se. It's per se. Not persay. Makes me nuts.
I worked in dog rescue for many years. You would think people would know that it's a German (or Australian :-) ) shepherd, not shepard. Dogs are sometimes skittish, not skiddish. The female has a litter of puppies, not puppys. After they're weaned, she'll need to be spayed, not spade, before she can be adopted.
