The Doggy dog dog

In my sudden haste
I use to claim all men had the characteristics 
of dogs
Until I came across
a Doggy dog dog
He had the look of a rednose pit
body well fit
something dangerously bad not to be reckoned with
This doggy dog dog
could stand his ground
when mutts was
gatherd  all around
If  you pissed him off
he'll surely put the 
dog down
He the type of breed unlike them all
this nasty kaynine 
was a true doggy dog dog
Strut his stuff
an told his lies
even cause tears at times to pour from eyes
He go out sniffing around
someone elses home
slip in an hump your lady dog if she's at home
Expensive in taste
capable of winning the race
this doggy dog dog had a distinguish taste
Be careful when you decide to bring one  of these breeds home
Or he'll do a doggy dog dog
move right in your home ?
