I don't know if this is the game from the new requester (it's for Win95), but I'm almost sure it's the original game asked. There's the electric fence, the kitchen, the lonesome feel. I didn't get to the end, so I don't remember anything about riding a dinosaur or a blonde girl.
Its name is "Escape Dinosaur Island" and I've found it only on
two sites.
EDIT: found it
here too.
