​Manager found this stuck to a dog treat; 2 and a half cm long pointed yellow capsule, stuck onto the treat with chewing gum. Possibly bloody q-tip inside

This is the only pic she sent, unfortunately; but as you can see it looks about 2 and a half centimetres long.

I work at a pet store, and my manager just messaged our work chat this morning showing that she found this weird capsule. She said it looks like it has some kind of bloody q-tip inside, and was stuck to the treat with chewing gum.

Obviously, this is freaking us out, cause we don’t know if someone was trying to poison a dog; the fact that it was stuck there with gum makes it seem really deliberate. Wtf is this?
