Last october my, then, 5 month old pup jumped up and turned on the cooker while we were out, he had also dragged something onto the hob and we came back to find the house on fire.
My boy thankfully was unharmed but the kitchen had to be gutted and the whole house cleaned and decorated. In fact the smoke damage was so bad we couldn't live in it for 3 weeks.
I have left my dogs in the kitchen for many years when going out and it just never occured to me.
