"Dog" is a countable noun. Since there are "three" of them, we must use the plural form dogs.

"Furniture" is an uncountable noun in English. Uncountable nouns do not have a plural form (so "furnitures" is incorrect) and they take a singular verb. "Couch" would need an article like "a couch" because it is a singular countable noun.
