Final answer:
The Wolf tooth in an equine is known as the B) First premolar and is often the first permanent premolar to erupt.
Step-by-step explanation:
The Wolf tooth in an equine is known as the B) First premolar.
The Wolf tooth is a small, peg-like tooth that is located just in front of the upper and lower first molars. It is often the first permanent premolar to erupt, hence the name 'Wolf tooth'.
Unlike other teeth, the Wolf tooth can cause discomfort for the horse when it interferes with the bit, so it is commonly removed for riding horses to prevent any issues.
