A dog rescued earlier this year after becoming trapped in a shipping container without food or water has died from complications from a fungal infection, according to a local animal rescue organization.

The puppy, nicknamed “Connie the Container Dog,” was found in January by Coast Guard marine inspectors from the Houston-Galveston Sector at the Bayport Container Terminal in the Port of Houston, where he had been trapped in a shipping container for at least eight days.

Coast Guard officials heard barking and scratching coming from inside one of the containers at the Port of Houston, and after lifting the container ashore with a crane, they found the little dog trapped in the darkness for days without food or water.

Since her rescue from the container, Connie, who was pregnant at the time, gave birth to eight puppies and was adopted by a family. Her puppies were also put up for adoption.

How did the container dog Connie die?

Unfortunately, Connie’s story of survival and rescue came to a sad end after she died from pythiosis, an aggressive fungal infection, Forever Changed Animal Rescue announced on June 28.

Pythiosis is an infection caused by a water mold-like organism called Pythium insidiosum, which is commonly found in water and may be present in soil, according to VCA Animal Hospitals, and can affect the gastrointestinal tract or skin.

Connie also had lesions in her gastrointestinal tract, and despite best treatment efforts, including advanced imaging, diagnostic tests and blood transfusions, her health deteriorated rapidly, according to emergency responders.

“After everything she had been through and survived, we just couldn’t believe her story would end this way,” the rescue organization posted on social media. “She was such a young dog, with the absolute sweetest personality, and yet she was such a fighter, a true survivor.”
