You’ve heard about a deadbeat dad — but what about a deadbeat doggy daddy?

A Manhattan marketing director is suing her surfer bro ex-husband, claiming he’s failed to pay more than $32,000 for the upkeep of their pet dog, a female fawn-colored English bulldog named Lola, since they split in 2012.

Sarah Bronilla, 39, married Josh Rosen, co-founder of the Soho lifestyle company Saturdays Surf, in 2006. The couple broke up a few years later and signed a separation agreement in September 2012, according to Bronilla’s Manhattan Supreme Court suit.

Since then Rosen hasn’t paid a penny to support Lola while Bronilla’s dished out $18,000 for dog food, $4,671.56 in vet bills and $12,000 for other expenses, according to court papers.

Bronilla “as of Sept. 10, 2012 has always and exclusively paid for all costs and expenses with respect to the upkeep of and dog food for Lola,” the single mom sniffs in court papers.

Rosen, who describes himself as a “perpetual child” in a 2010 interview, was supposed to regularly pay for and deliver the dog food to Bronilla’s Lower East Side apartment, send her $200 for other costs and split vet bills, the suit says.

After addressing the debts for her precious pooch, Bronilla mentions in the suit that Rosen also owes her $20,000 in alimony and $80,000 from the May 2017 sale of his share of Saturdays Surf.

Bronilla accuses Rosen, who now lives in Brooklyn, of neglecting Lola even though he’s apparently flush with cash since he received $1.6 million from the surf company deal.

She’s suing for a total of $132,000.

Rosen did not immediately return calls for comment.
