Hyper Jack russell driving us nuts, crate training....help?

you need to get up early and exercise the dog to the point of exhaustion every day before you go to work, at least an hour of strenous exercise ... you do not have to come home during the day as that only gets the dogs worked up and both of your dogs are old enough to hold it ... but when you get home the dog requires another hour of strenuous activity ... and don't forget a walk before bed ... the fastest and most efficient way is if you have a bike or rollerblades ... you can not leave a jack russell in a crate for a full workday without wearing the dog out first ... and your jack russell will not have to be crated for life ... i do not crate mine (she was crated till her first birthday) anymore and she has never soiled or damaged anything ... she is calm and quiet in the apartment ... but i take the time to make sure she is worn out physically so inside she just wants to sleep ... jack russells, despite their small size, require more exercise than a lab ... and when they do not get enough exercise, stimulation they turn their intense amount of energy to barking, aggression, destructiveness ... the obedience classes were great for my jack and i am sure will be very helpful for yours ...
