Blind lost dog find its way home

[Catherine]

She finds her way home with the help of a good shelter after four months of being lost on the streets. Who knows where she had been all this time.

After four months they must have given up hope of ever seeing daisy again.
Good thing the shelter people checked past records.

I thought cats were the ones who can back after long absences.
