BETHESDA, Md. (WJZ) — Since former President George H.W. Bush’s passing Friday, his service dog Sully has captured the hearts of Americans who saw the viral photo of the dog lying near Bush’s casket.

Family spokesman Jim McGrath shared a photo of the yellow Labrador Retriver sleeping next to Bush’s casket on Dec. 2.

McGrath has been sharing photos throughout the week of how the nation is honoring Bush 41.

Another photo showed Sully comforting Bush family members on Dec. 3 as they stood near Bush’s casket at the Houston funeral home.

Since then, people have wondered where Sully will go now that his mission with the Bush family is nearly complete.

According to former President George W. Bush, Sully’s next mission will be at Walter Reed National Military Medical Center in Bethesda, Maryland as a ‘facility dog.”

“As much as our family is going to miss this dog, we’re comforted to know he’ll bring the same joy to his new home, Walter Reed, that he brought to 41,” Bush posted on Instagram.

America’s VetDogs, the organization that assigned Sully to former President Bush in June after he was diagnosed with Parkinson’s disease, tweeted a sweet photo of Sully sleeping Monday, after a long day comforting mourners.

“It’s been a long solemn day. I don’t blame him for taking respite on my comfy bed.” said America’s VetDogs Service Dog Program Manager Valerie.

Here are some more photos of Sully.
