The possibility of becoming trapped deeper inside.
Whatever Daisy is waiting for, her body cannot safely keep repeating this routine indefinitely.
Her Thinness Needs More Than Food Alone
An underweight stray dog certainly needs appropriate nutrition.
But severe thinness deserves broader evaluation.
How long has Daisy been losing weight?
Can she eat normally?
Are parasites involved?
Is there gastrointestinal disease?
Dental pain?
Chronic illness?
Has limited access to food simply been the main problem?
Her appearance cannot answer those questions.
The Hind Leg Raises Its Own Set of Concerns
A dog refusing or struggling to bear weight on a rear limb may have an injury involving the paw, soft tissues, joints, bones, or nerves.
The pelvis and spine may also need consideration depending on examination findings.
Daisy's ability to limp out of the drain does not mean the problem is minor.
Dogs can remain surprisingly mobile while injured.
In Fact, the Bus Routine May Hide How Much the Leg Hurts
Daisy moves because something motivates her.
That does not mean movement is comfortable.
When she emerges quickly, her front legs do much of the work.
Her stronger hind leg pushes.
The weak side follows awkwardly.
Once she reaches her viewing spot, she stops.
That stillness may be behavioral.
It may also conserve a body that cannot comfortably stand for long.
After One Bus Leaves, Daisy Struggles Going Back
She turns toward the drain.
Her first few steps are slow.
The weak hind leg slips slightly as she approaches the opening.
Daisy lowers her front half.
Then pauses.
For several seconds, she seems to gather herself.
Finally, she disappears inside.
The entire trip may have lasted only a few minutes.
For Daisy's injured body, it was still work.
The Drain Has Become Her Base
It is where Daisy sleeps.
Where she retreats.
Where she waits between appearances.
She does not appear eager to remain exposed after the bus leaves.
That suggests the outside world is not generally drawing her out.
The bus is.
Even Food Does Not Always Produce the Same Immediate Response
Food placed at a safe distance can attract Daisy eventually.
But she may wait.
Watch.
Approach cautiously.
The bus is different.
Its arrival creates urgency.
Daisy begins emerging while it is still settling at the stop.
That difference makes the pattern difficult to explain as ordinary curiosity.
She Is Not Chasing the Vehicle
This matters too.
If Daisy simply reacted to the moving bus, she might run after it.
She does not.
Her attention appears strongest during the stop itself.
Arrival.
Open doors.
Brief waiting period.
Departure.
Then retreat.
The open-door interval seems to be the center of the sequence.
One Bus Arrives With Nobody Getting Off
The brakes hiss.
Daisy appears.
The doors open.
No passenger steps onto the sidewalk.
Daisy keeps watching.
The doors close.
The bus leaves.
She turns back toward the drain.
Whatever she expected, nothing visible happened.
Yet the next bus still brings her out.
Another Time, Several People Step Off
Daisy watches them.
Her head shifts.
Her ears move.
But she does not immediately run toward any one person.
That makes a simple conclusion impossible.
Maybe she is watching for someone specific.
