A savage dog that mauled several pets on the Upper East Side last year, killing one, has struck again — a year after its owner planned to put it down, The Post has learned.
Syko broke out of a car with two other “snarling” German shepherds Friday morning outside its owner’s since-shuttered bookstore on East 92nd Street — and then charged at a 71-year-old woman walking her dog, according to the victim and witnesses.
“The door flew open and these three giant dogs started attacking us,” said Lucy Davis, a 30-year Upper East Side resident who was knocked to the ground during the attack.
Shocking footage showed the septuagenarian on the ground with her arms wrapped around Oscar, her 11-year-old Cavalier King Charles Spaniel, while three men guarded them from one of the German shepherds.
Davis defended her much smaller pooch by punching one of the other dogs repeatedly in the snout before pushing away another that charged at them.
“I kept saying ‘No, no!’ and yelling,” she recalled.
A man in glasses meanwhile yanked a muzzled Syko by the collar and tossed the dog into the car, before turning around to handle a second pooch, video showed.
“If that man hadn’t gotten out of the car when he did, to call those dogs off, they would have killed my dog,” Davis said.
That handler repeatedly seethed, “She should have put these dogs down,” Davis said — referring to an earlier promise by Syko’s owner, Lynda Hudson, to euthanize it following the spate of attacks that terrorized the neighborhood.
Hudson had said she planned to put down Syko after the snarling pooch was blamed for injuring at least four local dogs last year, including a 7-pound toy poodle named Baby who was euthanized after its spine broke in the alleged attack.
In an apology letter to neighbors, Hudson claimed a vet refused her request to put down her vicious dog.
Baby’s owner Akiba Tripp said she began “shaking and crying” Friday after learning Syko had struck again — and just two hours after Trip had walked her new puppy, a 1-year old toy poodle named Lola-B, on the same block.
Hudson stood in the doorway of her former bookstore, La Librairie des Enfants, during Friday’s attack, expressing little concern about the chaos her animals caused, according to UES resident Tori Pratt.
“I just started screaming at her, ‘Your dog’s doing it again, your dog’s doing it again’ and she was so nonchalant about the whole thing,” seethed Pratt, 33, who is concerned the Hudson’s untamed animals will harm her dogs or even her young children.
The bookstore owner, who announced earlier this year she was relocating her business to the West Village, previously claimed she had been keeping her dogs at her home in Westchester County since last August’s fatal attack.
Hudson did not respond to a request for comment.
