Yes dogs can safely eat pasta if you want to feed the dog the pasta.
My dog loves eating pasta with me when I have pasta and he's eaten the pasta for many years now.
My dog also loves lasagna too which also has pasta in it.
Dogs can safely eat a lot of the food us humans eat and it's healthy for the dog to eat other human foods other than dog food.
My cat also eats pasta and lasagna with me too so cats can too eat pasta and lasagna.
