It would be easy to say he is too afraid to look at people, that someone hurt him in the past, or that he desperately wants affection but is frightened to ask for it.
None of those explanations has been confirmed.
There is no way to know exactly why Walter turns toward the wall.
What can be observed is the contrast.
When a person stops, Walter makes the physical effort to stand.
He turns his face away.
Then his tail begins moving.
That combination may be useful behavioral information for anyone considering Walter, but its meaning should be evaluated by the shelter staff who have actually spent time with him.
What should not be overlooked is the amount of effort involved.
Walter's body is already weak.
Standing is difficult.
Yet the presence of a person still gets him onto his feet.
Walter's Physical Condition Is Declining
Walter has a large tumor on his shoulder and is becoming increasingly weak.
No additional medical information was provided.
The tumor has not been identified here as cancerous or benign, and no biopsy results, imaging, diagnosis, treatment plan, or prognosis were supplied.
It should therefore simply be described as what has been reported: a large shoulder tumor.
Walter's medications, appetite, weight, pain level, and mobility assessment are also unknown.
Anyone interested in helping him should request those details directly from the shelter.
What is observable is that his overall strength is declining.
Getting up takes effort.
Remaining upright is difficult.
And the physical changes affecting Walter are significant enough that any potential placement would need to understand his medical condition before taking responsibility for him.
His History Before the Shelter Is Unknown
No information was provided explaining how Walter entered the shelter.
It is unknown whether he arrived as a stray, was surrendered by an owner, transferred from another facility, or entered through another circumstance.
