What is the difference between the warhorse where it comes to carrying capacity? Perhaps a home brew rule is in order.

A riding horse has a STR of 16, but both the draft horse and riding horse have a STR of 18.  Between the draft and warhorses, there is no difference in carrying capacities.  That said, warhorses are faster and have higher AC.  (Thematically, warhorses are trained not to be spooked easily, and willing to go into battle.)

how much does a horse weigh?

wanted to see what would be required to lift one. Cause bro, do you even lift.

The average weight of a domesticated horse is about 1000 pounds (or 454 kilograms). Picking one up would warrant some way to double a character's lifting capacity, as a standard 20 Strength fighter can only lift up to 600 pounds without any gear.

This is likely due to purposefully breeding horses for select tasks, in this case pulling heavy objects like carriages.

A wild horse will likely be much lighter, yet also won't be as strong. A player character centaur weighs some number over 600 pounds, so we can safely assume a wild horse weighs similarly.

Oh no, the hooves of terror!!!

that sounds like there's a story to that?

A larger horse, war or draft weighs between 1400 and 2000 Ib

hooves go brrrrrrrr

Breed Overview

It does more damage, has more health, etc. Ideal for battle

Wanted to see if a draft horse was better than a warhorse. I will remember this for my next session

summoning this with conjure beasts is a massive troll. Had my players pull it on me against a big bad, 32 draft horses in an endless tide of human wave against this one poor paladin.

I think a warhorse's barding should be counted towards that carrying capacity.

Is 2 intelligence not quite low for a mammal species? Horses can understand commands, show affection, demand food, etc. intelligence at 2 I’d have thought would be something like an insect or a fish that operates entirely on instinct. Just thinking from a “Speak with Animals” point of view, intelligence of 2 would barely be aware of its own thoughts and wants.
