When I read this it reminds me of the horror of unlimited surrender.
People can abuse, neglect, ignore and mistreat their dogs for years it seems as long as there is a resemblance of food. water and shelter.
Then they can deliver the no-longer wanted dog to the local SPCA and the next day or week get a new puppy.
The cycle of abuse continues.
Without intervention nothing will change and remember, these people have also taught their children that this is how you treat a dog.
