Yes, although when people ask if a dog is "kiltti" it usually means "does you dog bite (is it aggressive)?" and thus relates to being well behaved. When someone says that a person is "kiltti" that obviously doesn't tell anything about whether that person bites others or not, instead it just means "kind". :)
Unlike English, Finnish does not use auxiliary verbs like "to do" to start questions but a question particle. In yes/no questions, the particle -ko is added to the word that is in charge of the interrogation. Most often this word is a verb. The verb is followed by the subject.
- Onko Ruotsi kylmä maa?
- Is Sweden a cold country?
- Onko sinulla suomalainen nimi?
- Do you have a Finnish name?
Whenever the verb olla, "to be", is the chief interrogator in a sentence with several nouns as different parts of the sentence, the more complete noun or noun phrase is placed first. The first noun is usually translated with a definite and the second with an indefinite article.
- Onko kissa viikinki?
- Is the cat a Viking?
- Onko viikinki kissa?
- Is the Viking a cat?
