A 5-year-old golden retriever named Ike got sick during a dog road show, and this was way back in September.  The owners rushed Ike to the vet, and he was diagnosed with the disease that has dog owners in a panic -- canine infectious respiratory disease complex.

Ike was taken to a vet hospital and quarantined. Dogs can quickly go from a cough to life-threatening pneumonia with this disease.

The dog was given a "last-resort antibiotic," called chloramphenicol, which fights bacterial infections. The family of the dog told ABC7, within hours his breathing was no longer labored.

The owner, Becky Oliver, said, "It's a very, very strong last-resort antibiotic, but it's what saved him. Otherwise, he would not be here."

So far, officials, officials have not commented on the efficacy of the antibiotic.

The disease has been spreading ... it's been found in California, Oregon, Indiana, Illinois, Washington, Idaho, Nevada and in various states around the Northeast.
