This sheep had clearly had enough of being hounded when it decided to headbutt a sheepdog.
The angry sheep defied orders and charged at the Border Collie as the dog lay prone on the floor, gesturing as if it were preparing to pounce at the mammal.
After receiving a battering from the woolly attacker, brave sheepdog Jim was seen fighting back and nipping him on the nose and rounding him back up.
Jim, a fifth-generation border collie, then managed to force the sheep back into his pen.
Farmer Pay Byrne, who farms on 67 hectares of grass land, said he was trying to move the rams to another area when the confrontation took place.
Mr Byrne, from Roscommon, Ireland, said: ‘I was moving the rams to meet their girlfriends but they didn’t want to go.
‘They are really stubborn and always a challenge so I needed Jim to help.

Jim the Border Collie takes a mighty whack after the sheep uses its head to hurt the dog
‘I asked him to move them, as I watched I knew there would be a problem as the rams always challenge when they stop.
‘He knew he was going to take him on, it was payback for being moved.’
Border Collies try to herd animals by getting in front of livestock and staring the animal down to keep them in control with their motion.
The footage shows Jim successfully ‘stalking’ the ram, which is six times heavier than him, before it charged at him.
Mr Byrne, 55, said: ‘From experience I know how it was going to happen – so did the dog which is more important.
‘At no point was I worried about Jim – I knew he was in control.
‘It only took him one move to show him who the boss was and put him in place.’
However the sheepdog soon gets its own way and forces the sheep to run away back towards its own pen
