German Shepherd nibbling

Question
My GSD nibbles things with his front teeth such as sweaters, silk.  He also does it when he's excited.  Why does he do it and how do I get him to stop?
Thanks, Amy

Answer
Dogs don't explain why they do things.  In many cases, we have a logical explanation, but it is all guess work.  The nibbling can be an effective way of destroying things.  Again, I struggle to explain why.  

Damaged possessions are the fault of whoever was watching the puppy. When you are watching it, immediately correct it as soon as it goes for anything except its own toys. In a quiet, but firm voice give it an ''Ah, ah, ah!''. Offer her one of her toys, and hold eye contact until the puppy drops it.

A mousetrap is very effective in making a dog leave something alone. Most dogs will stay away from anywhere they were surprised by a snap. The best part is that it is not you that is correcting the dog. It works whether you are around or not. The mousetrap is very patient and is always on task as long as you reset it.

Better than mousetraps when you aren't around is the crate. 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.
