His name is shadow he’s microchip. He has on a black and white vertical stripe collar. He has white on his chest. He takes medication couple times through the night, but he’s very fast. I couldn’t catch him. he’s my ESA. I have CPTSD and depression and panic attacks and I need to find him. I’m scared to death and I’m sure he is too. He’s only a year old he scared but he won’t bite.
