The SPCA of Erie County said Saturday that Charlie, a dog that was found by sanitation workers in a garbage tote last month, has been put down.

The shelter said it had to make a tough decision to put Charlie down because he started showing some aggressive behavior.

The SPCA is offering a reward for information leading to the arrest and conviction of people responsible.

If anyone has any information, you’re asked to contact the SPCA at: 716-875-7360, ext. 221.
