Mine ate the Kong Ball, most of it anyway till I caught her!First 2 years are going to be rough, they like to chew and are very energetic puppies. I recommend a Kong ball.
A DOG IS A REFLECTION OF ITS OWNER, if you teach it to be friendly it will, on the other hand if you teach it to be aggressive IT WILL!
If you choose to get one please take the time to train her or him correctly
They are very stubborn, smart, strong willed and training is a fulltime job.
