“When you love something you have to let it go,” Lena Dunham writes in an Instagram post about a difficult decision she made regarding the happiness of her beloved pooch Lamby.
The pup, who had previously been a star on her Instagram page, hasn’t been seen lately, and the Girls actress was compelled to tell curious followers why.
“A lot of you have been asking where Lamby is these days,” she began in a lengthy post shared on Wednesday. “Well, you know honesty is my jam but this one has been really heartbreaking to talk about.”
Dunham revealed that last March the pup, “after four years of challenging behavior and aggression that could not be treated with training or medication or consistent loving dog ownership,” went to live at a professional facility in Los Angeles, where “an awesome person named @therealdanishay (who is educated in a rescue dog’s specific trauma) loves him so hard.”
She shared that the rescue dog — known on Instagram as @lamby_antonoff — had suffered “terrible abuse” in his past life that made a typical home dangerous for him and others.
“We needed to be responsible to ourselves, our neighbors and especially our beloved boy,” she said. “[My partner] Jack and I will miss him forever but sometimes when you love something you have to let it go (especially when it requires tetanus shots and stitches.)”
The star, who clearly struggled with the decision, promised to someday “really write about the pain and relief of letting Lamby go off and really be Lamby, biting and peeing in his own mouth and all.” She said the ordeal taught her “about forgiving myself and loving with an open palm and giving in to a larger plan.”
Dunham gave a special shoutout to her partner Jack Antonoff “for loving [Lamby] even when he ruined floors and couches and our life,” she explained. “Jack knows what Lamby means to me and he let me come to the decision in my own time even when it made his days challenging.”
She also encouraged others to “responsibly re-home” troubled animals rather than sending them back to animal shelters.
“It can require patience, diligence and often a financial contribution but there are solutions that leave everyone happy and safe,” Dunham said. “You will always have been your dog’s first stop outside shelter life and that’s beautiful.”
