They can still die before that though so be careful and love your little doggie!
if the chihuahuas are nice they can play with the cat. one time i had two chihuahuas and a cat and they played together. (im not sure what you ment when you say "Did chihuahuas can stay",sorry)
that can stay in the heat for like 10 to 20 days
There are both long-haired and short-haired chihuahuas, so both.
Twice a year.
Most all chihuahuas bark to much.
Some of them are the normal chihuahuas you see everywhere and the others are long haired chihuahuas.
chihuahuas can protect themselves by their speed,or hiding.It will probably hide but if it can't then it will snarl and will definitely not turn its back on its enemy
Twice a year.
Around 24 hours.
Chihuahuas are dogs. Not babies. Dogs should be loved of course but don't give them shoes. It looks silly. But if their feet start to blister from heat then yes, but only for that purpous.
