When The Wolf Sees The Sheep! Teddy Is A Menace On A Bike Ride!!

When you try to contain your dog's excitement when he sees loose sheep on the road and he's this big you've definitely got your hands full! I've tried stopping him but i end up supermanning the bike. Tactfully i've tried dismounting the bike judging the timing but this doesn't always end well either. I'm sure the farmers are playing tricks on me letting their rogue sheep out to test Teddy! He of course just wants to play and chase so I have to keep an eagle eye moreso than him on every corner. Sometimes the sheep even come up behind us and think we have food or something!
A 20 minute cycle with teddy can turn into an hour when you have to contest with the fluffy white ones aimlessly walking all the way you have to go home!
