and when you need to keep the mouth slightly ajar to look at lets say the tongue because your dog had a lapse in better judgment and ate a bee that stung his tongue and the stinger is still lodged in there...I found the rawhide sticks work well... place it toward the back of the mouth line so its between the back teeth resting between the top and bottom molars, this way you can get in the mouth and they are not biting your fingers and they cant close their mouth. And I used a face cloth as well to keep the tongue down. But yes you do ideally need two people to get it done quickly and less trauma!
