I have two Parsons terriers, I love them to death but for any other non-human they are demons and will attack any other animals (except pitbulls - which they seem to like and play with)
I have shorty broken coat Jack Russell. He has the best personality , loving, fun , full of energy, love people, playful, love mingle with other dogs. Only thing is ….his stubborn 🤣
I have a 3 year old shorty. She's not very personable to people since when she's outside all she wants to do is find and chase squirrels and other critters, and not much of a lap dog. She would rather burrow under a blanket to sleep when she's tired. She gets along fine with other dogs. Although she is tiny and often gets confused with a mini dachshund, she needs about 5 miles of walking per day, where she runs perhaps 10 miles when we're in the woods. I doubt any Jack Russel would be a good dog unless they get this amount of exercise. Despite her very short hair, she sheds year round.
I have a shorty. I just had his DNA tested since people are always telling me he cant be pure since his ears stand up. It turns out he is 100% Russel Terrier. He's cute and loves to play rough. He is super friendly to everyone and every dog. But he will fight if challenged or protecting his toys or food.
