We recently rescued a chihuahua. We have Noel who is a 16 month old Basenji. This chihuahua (named Bean) is so scared of Noel. bean will growl and try to attack Noel constantly. noel is so good with Bean. She will come close while bean is growling and as bean tries to bit, noel will move her face away and then back and away….I think noel is trying to show bean that she does not want to hurt him. Anyway...now I've got to try to work with bean and agression but Noel is awesome with him.
