Do Jack Russell terriers get along well with other dogs?

That all depends on how you train you dog. Sometimes Jack Russell's love to play with cats but other Jack's may want to kill it. So it mainly depends on where it came from, how you train it with cats, and if your dog responds well around cats. Sometimes the dog just doesn't like the certain cat or where it came from. My dog HATED our neighbors cat but when i brought my dog to my aunts house he was very friendly to my aunts cats.
