Source
This item is a possible reward from the quests 
[70] Back to the Orphanage and 
[70] Back to the Orphanage which begins with Orphan Matron Mercy in Shattrath City's Lower City during the Children's Week seasonal event.
Notes
Egbert is notable for frequently running around wildly and getting pretty far from his owner. Egbert responds to your character's run/walk toggle. If your character is set to walk, Egbert also walks around instead of running.
The other two item reward options from the quest line are Elekk Training Collar, or Sleepy Willy. Only one of these could be chosen, although theoretically when the event repeats itself next year you will be able to choose another.
