What to do if my dog is anxious home alone

Dogs are highly social pack animals. I've met many dogs that become anxious when separated from their owner. Separation anxiety is characterized by signs of distress when a dog is separated from an owner or family group to which they are attached. These signs can include toileting in the house, destructiveness, excessive barking, whining, crying, digging or pacing and attempting to escape, etc.

Separation anxiety can be a severe problem. Not only for the dog but also for their owners that might even get evicted because of the barking. The goal of training is to teach the dog how to stay calm and relaxed when the owner is absent.
