When the dog is naughty

Just like humans there are dogs that kind and behaved and there are the mischievous. We had our dog undergo more than 2 months of training on every other day session of 1 hour. But that did not change the behavior. He tends to quarrel with our other dogs.

The only remedy is to keep our naughty dog in a cage. At least that will give the other dogs peace and also spare the naughty dog from being fatigued in running around. He is comfortable in the cage anyway.
