Definitely write, as Jack Russells of any kind (Parson or regular) are NOT the dog for just anyone. As cute as they are as puppies, that's how destructive they can be if bored and neglected - like left home alone all day with nothing to do. They are terriers through and through, and that's why many end up in shelters. Terriers are great dogs for the right person, but a nightmare for the wrong person.
