10. Be Gone All Day
When you bring home a brand new puppy, he wants to be cuddled and loved. After spending a weekend of bonding with the little guy, you have to leave to go to work, and are likely gone for eight to ten hours. A puppy or an older dog doesn’t understand this concept, and they are left all alone in the house wondering where their owner went. Dogs are very annoyed when they are left all alone with no one to play with for the entire day.
