Great Dane Depression

Question
We have recently, four months, homed a 7 year old rescue great dane who has had a rough life.  She has no concept of a ball, a ring, of fetch.  She seems to take virtually no pleasure in anything.  Maybe food and when I first suggest and get out for a walk,  but then she lapses into a shamble of a walk.  She bucks up when she sees a rabbit but only just makes it into a run to catch it.
Her front teeth are worn right down and the top of her nose are has long term damage I can only assume from having the front of her mouth thru a steel mesh.
She very rarely can be sparked into any sort of gamble.  In short I am at my wits end to stimulate her into any sort of play, or attention

She barely acknowledges us when we come into a room after we have been out or in the morning.  By that I mean she cannot often manage to raise her head let along get up and wag.  

She rarely barks,  and then with no passion !!  or threat !!

Help......

Answer
You may never get her to play or show any emthusiasm for life if her past experiences have been so bad.  Lots of love, special treats when she shows some animation, like barking or preparing to go for a walk.  Lots of treats when out for a walk so that she associates 'normal' activites with enjoyment.

She has fallen on her feet in her later years so you may have to be satisfied with giving her the best you can.
