Now he’s fetching crypto sales from the great doghouse in the sky.

An adorable puppy influencer that prompted a bizarre cryptocurrency-fueled rigged New York City dog mayor election died suddenly in his sleep “without clear explanation,” his heartbroken owner told The Post Thursday.

“It was so sudden and shocking. I thought he had a few more years,”  Kathy Grayson said of her beloved Pomeranian, Bertie,  who died Tuesday.  “We’ve been together almost every second of every day for more than 11 years.”

Bertie — an 11-year-old Paddington Bear look-alike with nearly 400,000 Instagram followers — became the subject of a hair-raising scandal earlier this month when cryptocurrency fanatics hijacked a fun competition for “Honorary NYC Dog Mayor.”

A mystery tech geek first launched a crypto coin, named BERT after the dog, and began pushing the pooch’s candidacy on social media in an effort to drum up the value of the currency, according to participants and organizers.

The “pump the price” scheme — which allegedly included offers to pay for votes — unleashed a flood of electronic ballot stuffing and a suspicious spike in votes for Bertie.

Dog owners quickly began to howl.

One participant, Olivia Caputo, even yanked her lovable Shih Tzu, Enzo, from the competition after it amounted to “election fraud” and became too negative, she told The Post.

“That insanity spiraled out of control,” said Grayson, who insisted she had “nothing to do” with the cryptocurrency weirdness. “It was really cuckoo with people alleging election fraud — in a dog election.”

Stephen Calabria, who started the contest in 2022,  admitted that he noticed some bone-ified suspicious activity during the pup race.

“There were certain things that just didn’t seem right. Like blocs of 2,000 votes at once. It went from neck-and-neck to [Bertie] winning by 96 percent or something,” Calabria told the New York Times. “If I never hear the word crypto again, it will be a blessing.

A message circulating online also urged people to get an Instagram account to vote for Bertie —  declaring, “Post a few pictures. You know what I mean. Basically, don’t look like a bot.”

Grayson, an art gallery owner,  ultimately conceded the victory to a sweet-faced basset hound-mix named Simon.

“I said, ‘Bert will concede and the other dog can win,  just to make it fun again,” she said.

Bertie, who was adopted from a shelter in Oklahoma, was instead named deputy dog mayor of the Big Apple.

Grayson said her veterinarian has “no clue” what caused Bertie’s death, which came without warning while he was in good health. She suspects it may be linked to a blood clot.

The loyal fluffball lived an “amazing life,” complete with his own “meme coin,” an appearance on the “Rachael Ray Show,” and the title of deputy dog mayor, she said.

“He had star power and his face almost seemed to radiate love,” she said.

“He had an outsized personality. He was sassy and he almost seemed to have a sense of humor.”

Grayson posted a heartfelt tribute to her four-legged friend on Wednesday — saying he helped her through some very, well, ruff patches in life.

“We were inseparable,” she wrote. “I told him every day how much I loved him and how much he meant to me; he showed me every day how much he loved me back.

“Bert got me through my fiance Errol dying in 2016, my father dying a few months later, my mother dying two years later,” she said. “I wish I had more time with him, he was a priceless and unique individual. He had true star power.”

On Thursday, the value of the BERT cryptocurrency had plunged dramatically after peaking at an all-time high on Nov. 15.
