Bournemouth are still searching for their first home victory of the season after Harry Forrester's second-half equaliser for Brentford.
Simon Francis headed into his own net to give Brentford the lead before Matt Tubbs' header drew the two sides level.
Charlie Daniels then gave Bournemouth the lead from the penalty spot after Lewis Grabban was tripped.
But Forrester levelled with a strike into the top corner of the net for his first goal in senior football.
VIEWS FROM THE DRESSING ROOM
Bournemouth manager Paul Groves told to BBC Radio Solent:
"We probably created the better chances overall but they came and they were probably one of the better sides we have faced overall.
"I thought the lads in the first half were very, very good. They were dominant in terms of pushing the opposition back but you're never going to go through a game where you have a 90-minute spell so you have to expect the other side to have a go at you at some stage.
"It was a little bit frantic at times and we'd like a little bit more control in terms of possesion, but they made it like that in that respect."
