That is seriously fupped uck.
It happens all the time in our neighborhood which is located a couple of blocks from a large apt complex. People get a dog then when they have to move or they find out its hard to have a dog in an apt. they drive over in our neighborhood and dump it out.
Our Chihuahua Coco who is just the prettiest dearest dog on earth was running up and down the street craning up to look in every car that passed to see if it was her owner. It was just pitiful. After a few days I couldn’t take it anymore and brought her into our house. You could tell where she had had a collar and they just took it off and then dumped her.
Our other dog Buddy who passed in March was dumped at the lake behind our house about 12 years ago. He had a crippled back leg so I was afraid if Animal Control got him they would just put him to sleep. I took him also and he was just the greatest dog ever. We are still not over losing him.
