This entrepreneur started with an idea. A dog with a great deal of flatulence.

And, the book Walter the Farting Dog was written.

Then, the sequel…

Now, similar to Chicken Soup for the Soul (but with more talk about flatulence), you can get all kinds of variations of this book.

Walter Files a Malpractice Suit after some Quack Tries to Make Him Stop Farting…

Walter Goes on a Cruise after Dealing with Above Doctor and Discovers Margaritas.

After the Cruise, Walter Needs a Vacation and Heads to the Beach

Walter Learns a Bit about Business and How NOT to Treat your Customers

And, you can even get Walter the Farting Dog in various languages!

Spanish:

Latin:

The lesson here?

Lesson One. Animals with gas problems are hilarious!
Lesson Two. Everybody Toots.
Lesson Three. A bit of creativity, plus using real-life inspiration can turn into a very profitable formula for making money.
Lesson Four. When something works, run with it and branch off and expand!

A quick side note about choosing a niche.

When choosing a niche, consider the holidays. When your aunt asks your mom “What does your son do for a living these days?” — you may not want her to have to respond “Oh he runs sites selling dog fart stuff.”

Warmly,
Nicole (who has two puppies of her own)

PS. In your comments, be sure to include the names of your flatulent pets! (Or husbands….)

PS, again. I'm on vacation at a beach house with no internet access, so I won't be able to respond for a few days. Please don't think I'm being rude.
