Leviticus 22:21, 23

If a man presents a peace offering sacrifice to the LORD for a special votive offering or for a freewill offering from the herd or the flock, it must be flawless to be acceptable; it must have no flaw.

As for an ox or a sheep with a limb too long or stunted, you may present it as a freewill offering, but it will not be acceptable for a votive offering.
