There are many theories on this one. In some cases the cause or trigger can be pinpointed to a particular event, but often there appears to be no explanation for the Dog Separation Anxiety to commence. What I can say is that Separation Anxiety in dogs regularly occurs:

1. Straight after a change in routine. Such as your work hours changing or a family member leaves home. Remember dogs are creatures of habit and any changes can be very unsettling to them.
2. If you have been on vacation or unemployed for some time and have been spending heaps of time with your dog. When you go back to work your dog becomes anxious and distressed.
3. Unfortunately dogs rescued from animal shelters contribute a highly disproportionate number of Dog Separation Anxiety cases.
4. After your dog experiences a traumatic event while on his own. If a thunderstorm lashes your home while your dog is alone, this can trigger Separation Anxiety in the future.
5. If your dog is rarely left alone and becomes overly reliant on his human family - are very susceptible to this type of separation anxiety in dogs.
6. When you move house to a new neighbourhood.
