Five people were taken to the hospital Tuesday morning after a fire ignited in their mobile home.
The blaze broke out 14099 Belcher Road in Largo around 10 a.m.
Firefighters are investigating the cause and suspect kids were playing with matches, but are still looking into all possibilities.
A dog was also in the house during the fire and firefighters say the dog was found unresponsive. Fire crews gave the dog oxygen at the scene, and later took him to an emergency vet facility, where he is expected to recover.
The three adults and two children suffered smoke inhalation and are expected to recover.
The fire marshal will determine the cause of the blaze.
