A family's dog died in a blaze at a Mount Prospect home Monday morning.
Mount Prospect firefighters were dispatched at 10:11 a.m. to the home on Hi Lusi Avenue.
Smoke and flames could be seen coming from a second-story window when firefighters arrived, Battalion Chief Randy Uidl said.
"Pretty much the whole upstairs was involved in it," Uidl said.
"There was a lot of upstairs damage."
The residents were not home at the time. No one was injured battling the blaze.
