Jennie Garth -- Even Her Black Dog Gets Denied

It's tough to be in Jennie Garth's world if you're black. First she says her African-American friends were denied at a Hollywood club, and now her black Goldendoodle gets rejected by a fancy rover.

Jennie was tooling around the San Fernando Valley with her pooch Wednesday ... when her dog Pearl tried jumping in the back of her Range Rover. It was a gnarly, failed attempt -- dog vs. rover, and rover won.

It seems Pearl was no worse for wear.

TMZ broke the story, Jenny stormed away from DBA nightclub Monday night ... the club takes issue with her veiled claim of racial discrimination. They say she played the "Do you know who I am" card and was told she had to wait in line like everyone else.
