The sad saga of “Puppy Doe” has stoked outrage in dog lovers everywhere, spreading through social media and driving a flood of tips to cops searching for the sadistic sicko who tortured the young pit bull and left it for dead in a Quincy park.

Quincy police and the Animal Rescue League said they have been taking calls from as far as British Columbia since the atrocity was announced Thursday.

“The phones have been ringing off the hook,” said Quincy police Chief Paul F. Keenan, who had “two or three” people taking hundreds of calls yesterday. “There’s a lot of, ‘I think I saw that dog on this street,’ or, ‘That dog looked like a dog I used to have, and I gave it to somebody.’ We’ve had actually calls from dog whisperers and dog psychics. It’s gone crazy.”

Lt. Alan Borgal of the Animal Rescue League said officials were “overwhelmed” by nearly 500 phone calls and emails yesterday, including some from New York humane groups and at least one from British Columbia. Many wanted to donate toward a reward — the ARL is offering $5,000 for the tip that nails the degenerate — and others simply were well-wishers. Some callers reported bits of information they scraped from social media.

Police were chasing six specific tips — “We’re trying to figure out if they’re fruitful or not,” Borgal said, but declined to provide details — and they planned to keep on the phones through the weekend.

Borgal said officials waited to go public until the investigation confirmed that the starvation, broken bones, burns and dislocated joints were the result of daily torture. The young pit bull was euthanized because of the severity of its injuries.

“When this went out to the media yesterday, we had no leads,” he said. “If it’s a good lead, we’ll go out on that. If someone is nervous to call, they should do the right thing.”

Dorchester dog lover Bill Trabuco issued a rallying cry to fellow animal fanatics, saying he wants to raise $100,000 in reward money.

“I want to send a strong and resonating message to animal abusers that if you want to harm an innocent and defenseless animal, watch out, because we’re coming,” Trabuco said, adding that a big-bucks reward may be the only thing that can draw out information from the criminal’s confidantes. “No matter how loyal you are to this person, your loyalty has a dollar amount. Some people will turn their whole family in for $100,000.”

Trabuco tried to start an escrow account, but said the bank told him he had to set up a nonprofit, so he’s kicking in $1,000 to the ARL.

Keenan said tips are key because investigators have little other evidence. The dog was not microchipped, he said, and police so far have recovered no surveillance video from the Whitwell Street neighborhood where a Samaritan found the suffering pup Aug. 31. They still don’t know how it got there, he said, though they’re sure it didn’t travel far on its own.

“It’s a tricky investigation, especially where nobody witnessed anything,” Keenan said. “If somebody says, ‘That’s so and so’s dog,’ maybe we can go down and speak to them.
