Every year, hundreds of dogs go missing or are abandoned. They live as strays, rummaging bins for whatever food might be there. The dirt and the lack of shelter eventually cause them to develop ailments. Some eventually cross the rainbow bridge in this state, but fortunately for others, they are rescued and handed into local animal shelters where they receive treatment from kind hearts like volunteer vets in Surrey.
Usually, searching for owners are a futile attempt as the tags or collars are either gone or the writings have become illegible.
