The Little Coat For The Dog
There can be two cases here: The first one being that the dog grew bigger in the time of the arrival of the coat and the second can be that the company sent over the wrong size (which looks plausible to us!).
These people were not yet done with the size issue in their clothing that they bought online, so, they decided to shift to their dogs. We guess they would have expected this to happen. Why should the pets be left out of the fun? They deserve much more than us.
