PITTSBURGH (KDKA) — The Western Pa. Humane Society says the neglected dog found last week during the arrests of suspected drug dealers has passed away.

Reggie, a 3-year-old mastiff/pit bull mix, was severely emaciated – 30 to 40 pounds underweight – and was transferred to the Pittsburgh Veterinary Specialty and Emergency Center to be treated and monitored.

According to the Humane Society, veterinarians there spent several days trying to stabilize him, but today he was diagnosed with pneumonia, which was a severe setback to his already delicate condition.

Because of his deteriorating situation, officials say they made the decision to humanely euthanize him.

The Humane Society says Reggie “died amongst many warm blankets and toys” and with many loving staff members around him.

In a press release, Shelter Director and Director of Governmental and Community Relations Mary Withrow said:

“It is with very, very, heavy hearts that we report this news. Reggie fought as hard as he could, even before he came into the Western PA Humane Society family. We fought as hard as we could for him to have a chance. The fact is, it was too late. There are many dogs this happens to daily. It isn’t right. It can be prevented. The Western PA Humane Society will continue to work relentlessly to change laws and educate the community. In the end, we need to be the voice for abused animals. Our community needs to come together and report suspected animal abuse and be the voice for these animals who cannot speak for themselves.”

Reggie was discovered last Friday in the Glassport and Port Vue areas during drug raids.

Earlier this week, Reggie was given a blood transfusion, but officials say his condition continued to worsen.

Withrow tells KDKA that anyone who sees or suspects animal abuse, should report it before it’s too late, like in Reggie’s case.

“I just would like to say to people, please say something,” she said. “If you see abuse, if you see neglect, if you see cruelty, speak up. Please. Don’t let this happen to another dog. Let the community pull together, let’s do this, we can do this and fight this.”

Any donations made to help with Reggie’s care will be used to help other animals like him who need special care.

An investigation into his case is pending.
