5. Inappropriate Elimination

Inappropriate urination and defecation are among the most frustrating dog behaviors. They can damage areas of your home and make your dog unwelcome in public places or at the homes of others. It is most important that you discuss this behavior with your veterinarian first to rule out health problems. If no medical cause is found, try to determine the reason for the behavior, which can come down to one of the following:

• Submissive/Excitement Urination
• Territorial Marking
• Anxiety
• Attention-seeking
• Lack of proper housebreaking 

Inappropriate elimination is unavoidable in puppies, especially before 12 weeks of age. Older dogs are another story - many require serious behavior modification to rid them of the habit because you must often alter their perception of themselves.
