Tim Tebow broke down in tears while feeding his dog Bronco one last snack.

“One of the toughest goodbyes,” he wrote under the Instagram video posted Wednesday. “Wanted to make a special tribute to the sweetest boy ever – thank you for all the joy you brought and all the memories. Aunt Patty, thank you for loving him, and thank you to all the other people including Miss Shea and Miss Mindy for sharing so much love with Bronco. If you had the pleasure of meeting Bronco, one of the best dogs ever, I would love to hear your story.”

The Mets minor-leaguer and ex-NFLer received the Rhodesian ridgeback as a gift in 2010 after being drafted by the Denver Broncos — the pooch’s namesake.

Tebow also shared a cache of photos of him with Bronco on Thursday, including one of a special burial spot.

“Im so thankful and humbled by everyone’s support, prayers and love,” he wrote. “I was able to lay Bronco to rest in a really special place. Thank you all for so much encouragement. I love you Bronco, thanks for being the sweetest boy.”
