My Chihuahua who is 7 months goes every where with me. I haven't started to crate train him. He has been left alone only one time for maybe a hour, when I came back; he was freaking out like he had never seen a human before. I also bring him to my moms house almost everyday because she babysits for me when I can't bring him along. Does he get confused going back and forth between the house? and, also is it too late to start crate training him? I think I feel bad leaving him in a crate for hours( just seems wrong) but, I have no life because I'm always with Marley.
