Learn Romanian: Câinele inteligent vede totul aici. - The smart dog sees everything here.

The verb a vedea (to see) belongs to Conjugation 2, which includes verbs ending in -ea. To make the present tense "he/she/it" form, we simply drop the final -a, giving us vede (he sees).

Why is the word for "the dog" câinele and not câineul?

Masculine nouns usually take the ending -ul to mean "the" (like bărbatul for "the man"). But if the base noun already ends in an -e like câine (dog), we add -le instead to make it flow better. So, câine + -le = câinele.

Why is inteligent placed after câinele?

In Romanian, adjectives almost always come right after the noun they describe. So instead of "the smart dog", you say the equivalent of "the dog smart" (câinele inteligent).

Why does the sentence use totul instead of just tot for "everything"?

Tot generally means "all". When it stands completely on its own to mean "everything" in a sentence, it takes the definite article -ul. You can think of totul as literally meaning "the whole" or "the everything".
