Often I hear my puppy is chewing up my shoes, my sprinklers, my hands, and my credit cards, etc. How to stop this destruction? One of the golden rules is never leave a puppy unattended when at home and restrain the puppy or dog when you can’t watch him. This way bad behavior won’t be developing when you are not watching your puppy. Crates, kennels, x-pens, and leashes are some of the tools used to restrain a puppy. In the meantime, you can start teaching your puppy through the seeding game which toys are his/hers and which items are not.
