Are they high strung or always “ON” like Jack Russells?
Rat Terriers are mistaken for Jack Russels in appearance many times, but spend a little bit of time with these dogs and you will soon realize that the similarities end there. They dogs have ‘spurts’ of energy, they will run, play fetch, run around the yard with you, but honestly, if you sit down for more than 60 seconds, these little guys are looking to curl up in your lap.
