An investment banker was charged with starving his dog at his Tribeca pad, after his concerned ex-girlfriend brought the pup in for a check-up.

Craig Rosenberg, 32, allegedly “refused to feed, groom and walk” his 4-year-old golden doodle, Bojangles, according to a criminal complaint.

Sara-Ashley Bischoff was dog-sitting for her ex-beau on June 16 when she became worried about the pup’s health and took him to a veterinarian, court papers state.

Dr. Elizabeth Pearlman determined that the dog “was underweight, his fur coat was severely matted, and [he] has dental disease” and reported the alleged neglect.

Rosenberg was charged with one count of overdriving, torturing and injuring animals.

Bischoff, through her attorney, declined to comment. Rosenberg didn’t immediately return a request for comment.
