BRANFORD, Conn. (WTNH)– An investigation is underway after a dog was found abandoned and suffering from frostbite in Branford, early Sunday morning.

According to the Dan Cosgrove Animal Shelter, the dog was found near the Branford Community House by a jogger, who then called the animal shelter. The shelter says they received more information that leads them to believe that the dog was abandoned some time around 11:30 p.m. Saturday night, even though he was not found until around 7 a.m. the next day.

The animal shelter says that they have now opened an investigation into this dog abandonment. The dog was left with only a little towel in the cold weather so not only was he freezing, but he also appears to be suffering from frostbite on his paws which makes it painful for him to walk.

The veterinarians who then treated the dog gave him a body condition of between 2-3 . He also is at least 10-20 pounds underweight, has démodex mange, overgrown toenails, and appears to have pressure sores from being crated.

 PETA is now offering a reward of up to $5,000 for information leading to the arrest and conviction on cruelty charges of the person(s) responsible for abandoning this dog.

“This dog needed veterinary care or to be taken to an animal shelter, but instead, someone abandoned him on the street with no protection as temperatures plummeted to single digits,” says PETA Vice President Colleen O’Brien. “PETA urges anyone with information about this dog to come forward immediately so that the person(s) who utterly betrayed his trust can be held accountable.”

The dog is now being cared for by the Dan Cosgrove Animal Shelter who named him Lincoln. Due to his condition and the need for rehabilitation, Lincoln will not be up for adoption. However, the animal shelter will be giving updates on his condition on their Facebook page.

Anyone who has any information regarding the dog is urged to contact the Dan Cosgrove Animal Shelter at 203-315-4125 and all information will be kept confidential.
