How to make Object disappear OnTriggerEnter? For prefab shooting

hi, this is my code for making the hotdog hit the enemyBear to make it disappear.

I can get the shooter to work, but it doesn't work when the object hits the enemyBear.

using UnityEngine; using System.Collections;

public class HotdogCollision : MonoBehaviour {

     void OnTriggerEnter(Collider other)
     {
     if (other.gameObject.tag == "enemyBear") 
     { 
         Debug.Log (other.gameObject.name);
             Destroy(other.gameObject,3f); 
         }
     }

}
