Being a Chihuahua owner myself... On average, the life expectancy of a Chihuahua can be up to 15 years. You have to also factor in the breeding of each dog and their general health over the years. I had a purebred that past away after 11 years, and I currently own a Chihuahua mix who is going on 14 and very healthy.
.I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
