An apostrophe is used to signify ownership. To figure out whether or not the apostrophe is used correctly look at these examples:
My mom's dog is adorable. Correct Use of apostrophe
(Who owns the dog? Answer: Mom owns the dog. The apostrophe shows her ownership.)
Dog's are so adorable. Incorrect use of apostrophe. (The dog isn't owning anything or has possession of anything so the use of the apostrophe here is incorrect.)
