The Bleachers singer is sticking up for his girlfriend after her difficult decision to give up her beloved dog.
Jack Antonoff is standing behind Lena Dunham.
The Bleachers singer took to Twitter after his girlfriend defended the reasoning for her choice to give up her dog, Lamby, after the Brooklyn shelter where she adopted the pet claimed that several claims she made about the dog's history and aggression were not true.

"Nobody on earth cares for or loved lamby more than lena," Antonoff, 33, tweeted. "After he bit her father and her twice we found a trainer who deals with aggressive dogs who he now lives happily with. was a deeply hard decision."
"Shoutout to everyone who has an opinion on this and didn't live with us the past 4 years!" he added.
In Dunham's initial post about giving up Lamby, the Girls star wrote, "After four years of challenging behavior and aggression that could not be treated with training or medication or consistent loving dog ownership, Lamby went to live at an amazing professional facility in Los Angeles @matt_thezendog where an awesome person named @therealdanishay (who is educated in a rescue dog's specific trauma) loves him so hard."
The pup's new caregiver has since shared a plethora of snaps and videos of Lamby in her new digs.
Following Dunham's post, Robert Vazquez, a spokesperson for the BARC shelter, from which Dunham rescued Lamby, told a different story of the dog's past.
“We checked the records for Lamby,” Vazquez told Yahoo Celebrity via email. “He was ‘owner surrendered, not enough time,’ so we do not know where she got ‘multiple owners that abused the dog’… When she adopted the dog from us, it wasn’t crazy. I have pictures of the dog loving on Lena and her mom, which is weird if the dog was abused. It wouldn’t be cuddling with her or be in the bed with her ‘boyfriend’ in the pages of Vogue.”
After seeing the shelter's comments, Dunham shared a response on Instagram.
“I hope those judging can imagine the incredible pain of letting go of your favorite creature on EARTH because you know you can't help them be healthy and happy," she wrote. "I would never say an unkind word about the staff of BARC, what they do is amazing and life saving for these animals- but we have different accounts of Lamby's behavior and they were not present in my home nor did they live with him for an extended period. They did not witness the consistent and responsible care I provided.”
