What would you do? There's this abandoned dog in my neighborhood.

4. We had publicity about a similar dog here.

and it made headlines,,,he was known as the Wal-Mart dog because he hung around the local Wal-Mart.
All summer long Animal Control tried to get him, finally succeeding with one of the traps.

After capture my vet, who is on the Animal Shelter Board, examined him.
The poor thing was loaded with heartworms and other worms, had mange, was mal-nourished, had other problems.
Sadly, he did not survive the heartworm treatment.

Assuming your dog can be caught
and assuming he is or can be medically sound
he will need to be socialized, obediance trained, house broken, and never be off leash again.

There may be some folks who can provide ALL of that to make sure he does not end up running loose again.
