An assault with some dead obnoxious flea infested Mexican mutt?
I'd say this nutty broad was dog-gone mad.

ST. PETERS, Mo. - A woman angry that her new puppy had died pushed her
way into a dog breeder's home and repeatedly hit her on the head with
the dead Chihuahua, authorities said.

The 33-year-old woman told police she had taken the puppy to a
veterinarian, who said it was only 4 weeks old and needed to be
returned to its mother. But before she could return the puppy, it died.

Early Wednesday, the woman went to the breeder's home, pushed her way
inside and began fighting with the breeder as she tried to make her way
to the basement to get another puppy, police said.

The breeder wrestled the woman out of her house to the front porch,
where the woman then hit the breeder over the head numerous times with
the dead puppy, the St. Louis Post-Dispatch reported, citing police.

As the woman drove away, she waved the dead puppy out of the car's
sunroof and yelled threats at the breeder, police said. She later
called the breeder and threatened her and her family, according to
court records.
