Meet Sully H.W. Bush.

The golden Lab is the new service dog for former President George H.W. Bush.

He can do just about anything, including answer the phone. And he's on Instagram.

"As one person said, he can do just about anything except make you a martini. But not to worry, he can go get you someone to make you a martini!" Bush spokesman Jim McGrath told CNN.

A great joy to welcome home the newest member of our family, "Sully," a beautiful -- and beautifully trained -- lab from @AmericasVetDogs. Could not be more grateful, especially for their commitment to our veterans. pic.twitter.com/Fx4ZCZAJT8 — George Bush (@GeorgeHWBush) June 25, 2018

Sully can open doors, pick up items and summon help but "more than anything else the dog will be a wonderful companion," said an aide, Evan Sisley.

The former president posted a photo on Twitter of him and Sully posing with Bill Clinton, who was visiting Bush's home Monday in Kennebunkport, Maine.

Since developing a form of Parkinson's disease, Bush has used a wheelchair and an electric scooter. He has been hospitalized several times recently. His wife of 73 years, Barbara Bush, died in April.

"He's a really sweet dog," said Sisley, who hopes that Bush's use of a service dog will call attention to the organization and to service dogs.

Sully was trained by America's VetDogs , a nonprofit that provides service dogs. He is named after Chesley "Sully" Sullenberger III, the pilot who in 2009 landed a damaged jet on the Hudson River and saved the lives of the 155 people on board.

Bush, a dog lover, has had dogs since childhood, and man's best friend is always welcome at the family home. Two of the former president's children, Neil Bush and Dorothy Bush Koch, together have five dogs there, and other family members bring pets with them when they visit, Sisley said.

Special visit today with a great friend -- and now, a best-selling author. Luckily I had a freshly laundered pair of @BillClinton socks to mark the occasion. pic.twitter.com/v9jb4sRexh — George Bush (@GeorgeHWBush) June 25, 2018
