Even the best dogs can sometimes have behavior issues that need to be addressed. Some behavior problems are problems only in the owner's mind, because their dog is exhibiting a behavior like scavenging for food that, while normal for dogs, is unacceptable in human households. Other problems, like separation anxiety, are more psychological than behavioral, but the damage resulting from them is just as trouble-some, if not more so. Treating behavior problems requires consistency, good management, and patience.
