Castration is an important step but may or may not stop it. 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.

Other dogs may not be as bad as the young Labs I am plagued with. Still your house and dog will be much safer with the dog in a crate when you are away. 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. They are harder for dogs to open too. 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, make take some work. Start out just putting its toys and treats in the crate. Praise it for going in. If you have been able to trust it with any bedding, put that in the crate. Feed it in the crate. This is also an easy way to maintain order at feeding time for more than one dog.
