59. Combination Grades 



A dog may receive some combination of the 

 above grades ; some examples are : 



a. MO-GR. In this case, the dog may pass the 

 target, then return to it and sit. The dog receives 

 credit for a GR. Also, the handler may recall 

 his dog past the target and send it out one time 

 to try for a GR. 



Note. When the wind is blowing down trail, a dog 

 may have to pass the target to pick up the scent cone, 

 and then work back to the target. In this situation the 

 dog is given a GR. 



b. BR-GR. A dog may locate a target but not 

 sit; move on, then return and sit. Or, a dog may 



sit more than 3 feet away, and correct its posi- 

 tion on its own; or the handler may give his dog 

 the commmand NO, and the dog may correct its 

 position. 



c. BR-MO. A dog may locate a target and not 

 sit, move on, be recalled and moved out again, 

 and pass the target again without stopping.

 given is used for calculating the dog's grade for that 

 lane.
