"When you put the peanut butter on the banana, I mean you would think It was just the best day of his life," she said.
One last adventure before saying goodbye
The one thing he didn't like was stairs.
"We never could figure out why, but he just needed a lot of encouragement to go upstairs," she said, adding that the 80-pound pup once had to be carried up four flights of stairs when he was "being especially stubborn."
Hammett said she knew Charlie wasn't doing well at the end, so they took him for one last adventure before they had to put him to sleep.
"He spent his last days in his favorite place, the beach," she wrote. "He relaxed in the Charlie-sized holes he dug himself and dove straight into the oncoming waves. His last days were so happy and will be cherished forever."
Hammett said their home seems pretty empty without Charlie, so she and her husband plan to adopt another dog soon.

And the rarest breed ... English foxhounds
The English foxhound is the rarest breed in the new rankings. The sizable, high-stamina and vocal hounds have a long history in the U.S. but aren’t often found as purely house pets. Fans tend to deploy the dogs for their traditional, pack-hunting purpose.
“It’s a beautiful breed. I just don’t think people see them enough to know about them,” says AKC spokeswoman Brandi Hunter.
