Pamela Anderson -- Rick Salomon's Dog Is Fine! But His Daughter Calls Cops

Pam Anderson claims the ruckus over the allegedly "missing" dog Bumblebee is all for nothing ... but Rick Salomon's family is crying foul -- and Rick's daughter got into a standoff at Pam's house.

After a rough day that included her husband filing for annulment, Anderson went out in Bev Hills ... and told our photog the family pooch was fine, and simply at the groomer. She laughed off the idea she was holding the pup hostage.

But sources close to Salomon tell TMZ the family went to the groomer Thursday ... and came up with no pooch. Rick's fam claims Pam is lying about Bumblebee's whereabouts.

Meanwhile, Rick's daughter Tyson had her own issues. Law enforcement sources tell us L.A. County Sheriff's deputies had to go out to Pam's house Thursday night when Pam refused to let Tyson in to grab some of her stuff. We're told Pam never caved ... turning Tyson and deputies away.

Bottom line ... looks like Rick and her girls will have to sue to get anything out of the house.
