It wouldn't hurt to have a vet check, but it really sounds like a challenge to your leadership. Ask the vet about neutering him if not already. It can do wonders in these cases, although not a sure thing.

The key to most behavior problems is approaching things using the dog's natural instincts. Dogs see all the people and dogs in the household as a pack with each having their own rank in the pack and a top dog. Life is much easier if the 2 legged pack members outrank the 4 legged ones. You can learn to play the role of top dog by reading some books or going to a good obedience class. A good obedience class or book is about you being top dog, not about rewarding standard commands with a treat.

When you are around you need to keep a close eye on the dog. Use closed doors or gates to keep it in the same room as you are, and perhaps as I do, a short chain fastened to the computer desk. If you catch it in the act, give it a sharp ''Ah, ah, ah!'' and take it out. When you can't watch it, crate it.

It is only natural that a puppy resists its crate at first. What the puppy
Wants more than anything else is to be others, you, anyone else in the
Household, and any other pets. In our modern society, even if we are home,
Other things distract us from the attention an uncrated puppy must have. The
Only real solution is to crate the dog when you aren't around. The dog may be
Happier in its den than loose in the house. It relaxes, it feels safe in its
Den. It rests, the body slows down reducing the need for water and relieving
Its self. Dogs that have been crated all along do very well. Many of them
Will rest in their crates even when the door is open. I think the plastic
Ones give the dog more of a safe, enclosed den feeling. Metal ones can be put
In a corner or covered with something the dog can't pull in and chew. Select
A crate just big enough for the full grown dog to stretch out in.

Leave it some toys. Perhaps a Kong filled with peanut butter. Don't leave
Anything in the crate the dog might chew up. It will do fine without even any
Bedding. You will come home to a safe dog and a house you can enjoy.

A dog that has not been crated since it was little, may take some work.
Start just putting its toys and treats in the crate. Praise it for going
in. Feed it in the crate. This is also an easy way to maintain order at
Feeding time for more than one dog.
