9. Assuming the Dog Will Remain the Same
Your dog -- much like humans -- will experience changes in his lifetime. As he gets older, his looks, habits, and even personality may change. If your dog is exhibiting bad behavior, you don't have to accept that as just how he is. Instead, with proper training and care, you can transform your pet into a completely different, well-behaved member of your family.
10. Not Keeping an Eye on the Pup
It is impossible to keep an eye on your dog 24/7. However, when you know your dog tends to chew and be destructive, you should remain aware of where he or she is. Your Shih Tzu is not so cute when they are tearing apart rugs, clothes, walls, furniture, and whatever else they can find. Try to spend as much time with your dog as possible, and enlist the help of other family members or a pet sitter when you're too busy.
