Puppy Dog Tales was very juvenile and boring, and was only three short stories about dogs. Yes, I love dogs - I happen to own one - but I don't like reading stories about them that seem to have very little point.
M was too short, lacking in character development, and honestly doesn't even make sense unless you read the book description. Even so, it doesn't live up to the description and makes you wish you hadn't read it.
I gave these books one and two stars, respectively, on Goodreads.
