Okotoks Fire & Rescue responded to a fire just south of town on Friday, July 11.
The fire broke out shortly before 8 p.m. on Range Road 293, off 32nd Street.
A black plume of smoke from the blaze was visible across Okotoks.
"It came in as a structure fire," said Okotoks Fire Chief Trevor Brice. Crews arrived on the scene in about 10 minutes.
"We thought initially that it was a house fire, but it was actually the RV in front of a house," said Brice. "By the time the crews got there, it was fully involved. So, really, we were just defensive firefighting outside it."
Brice said the nearby home sustained only minor damage thanks to the quick response.
"The heat from the flames did crack the windows of the residence. I think if we’d been there another three or four minutes later, that would’ve started to burn as well."
Sadly, three dogs inside the RV died in the fire.
The cause of the fire is still under investigation.
