Dogs are smaller so potentially less dangerous and can be put on a lead.
Nope. On average in the UK 4000 people are attacked by dogs 70% attacked are children.
I am unable to find similar stats for horse attacks so this would show that dogs are much more dangerous to humans than horses.
Cyclists can control their bike, it is not unpredictable in its temperament like a horse can be. Schools teach cycling proficiency to children so they can follow road safety.
Apparently they cannot control their bikes given the comments on here how they slide on mud/horse shit so frequently.
Again road safety assessments are not mandatory so anyone can just ride a bike on the road and they do.
At least with horse riders we learn for many years as do our horses in order to be safe on public pathways. I have never once lost control in 20 years of riding public highways. I have had countless incidents of idiot drivers/Cyclists not following the highway code and driving like dicks.
Police horses are different entirely, it is used for the safety and protection not a hobby!
No they are not they are just horses like mine. Mine is what is called bomb proof. Unlike the police horses last year who refused to cross a rainbow crossing 
Police horses are used for all manner of things which is not always protection.
Thing is you hate horses and their riders. You will use any shit comparison you can in order to be goady.
Well it's worked the majority think you are a goady idiot.
