SAN DIEGO - A local puppy owner is warning others after she said she uncovered a trail of fake records and shady stories.
More than a week ago, Jaceil Daguison said she saw a photo of a pug-Dachshund mix on a Craigslist posting for a rescue dog in need.
"The posting said he was vaccinated, healthy and ready to go home," said Daguison.
Daguison said she met the seller that same day and was told the breeder wanted a therapy dog, but the litter was too big.
"He was goofy and spunky, and I fell in love," said Daguison.
Daguison said the woman told her the puppy was eight weeks old, and she handed over a vaccination record that confirmed the puppy got his first round of shots.
"You can see we have a record of Parvomune, signed by Ruben Sanchez," Daguison said as she showed 10News the record.
Daguison paid nearly $300 for the puppy she named Oliver.
However, two days later, Oliver was diagnosed with worms and a parasite. He then stated vomiting and had diarrhea, and tested positive for Parvovirus.
"It's heartbreaking and heart-wrenching to see him so sick," said Daguison.
It was heart-wrenching and a bit baffling, considering the records.
Daguison said when she called the listed veterinary clinic, she was told the named veterinarian on the vaccination record didn't exist.
Daguison said she searched Parvo on Craigslist and immediately found the other puppy pictured with Oliver. That puppy had just died of the same disease.
"The owner had two little girls and that was supposed to be their Christmas gift," said Daguison.
Daguison said she and that owner posted warnings online and received a flood of emails from more than 17 other families who dealt with the same woman. All but three of the puppies have died.
"It's disgusting and so low," said Daguison.
The San Diego Humane Society confirmed they've launched an investigation.
"Not only is she making dogs sick, she is putting many families through pain and suffering," said Daguison.
Because the woman hasn't been arrested, 10News is not naming her.
The owner of the veterinary clinic says in the past few months, he's received between 25 to 30 calls from other puppy owners asking about vaccination records that were faked.
Oliver's condition remains critical.
A GoFundMe campaign has been set up to help with bill, already more than $5,000.
