Lawn Replacement with Clover help Please.

I live on Long Island, New York.
This Sunday, as we were walking through a meadow at one of the County Parks, I noticed some clover and thought that this might be a great alternative to a Lawn for my back yard -- the big dogs play there -- I do not need a "golf course!"

I had heard that there are varieties of Clover that would work, including Dutch Clover.
I also ran across an advertisement from ClydeRobin Seed company -- I do not know anything about the company.
He was selling a product called "NO MOW!" -- perfect for me.
The following is a quote from his website:

"NoMow contains miniature English Lawn Daisy, Carpet Alyssum, Baby Blue Eyes, Red Yarrow, Dwarf flowering clover, Dwarf fine leafed grass, and other herbaceous plants".

Suggestions, comments -- please.
Thanks.
