Thanks everyone .

Well... turns out Willow was actually a male and named Smokey, a different vet checked for a microchip and found one. He is 15.5 years old, has a tumor on his shoulder and has some memory loss and is allowed to roam .

The owners said he will often wander off and be missing for a week, and then return home again. Their vet has said in the past that he should have died 5 years ago (They thought he would not survive this long) when they found the tumor , but he keeps on kicking.

I am glad he got to go home though, and hope he will be happy and pain free for his remaining time on earth.
