However don't take him each time you go out, otherwise when the time comes that he cant go with you he won't understand and there is not any way that you're going to be well placed to explain that to him. If this is a likelihood try to not spoil your Chihuahua too much or else you will both suffer. Socialization is vital for a well changed puppy dog.
