Dear Dr. Fox: I recently acquired a female Chihuahua from Canine Castaways. She is 5 years old. She can be very timid but gets quite vocal and aggravated when my husband gives me something or touches me. She doesn’t snap but looks as if she will. She has not nipped him, but she will not go with him unless I give the OK. Other times, she will sit with him and play.
How can I lessen her aggression with him? When going for walks, she will go only if I am with them. We have had Chihuahuas before, but they have always treated us equally. We would like her to be a two-person dog. – M.W., Naples, Fla.
