Well, this question definitely depends on whether you believe that horses changed at all, which you probably do if you are asking this question!
This is a hard question to answer, because there is no hard proof on either sides of opinion.
Some people, like myself, believe that a God created everything just how it is now.
Others believe that everything has evolved from tiny cells that were on the earth millions of years ago.
So if there was an answer to your question, it would just be someone's own beliefs and opinion, and so there is not really any right or wrong answer for this question.
People cannot change the actual color of the hooves. But they can paint them with hoof polishes that come in many different colors and some have glitter in them. But these polishes shouldn't be left on for long periods of time as they prevent air from getting to the hoof.
Yes they are. Even though donkeys have these type of hooves and it is easy for them horses have a hard time with this type of hoof. It tends to make them off balance,and hard for them to run properly.
Over time they evolved from having normal feet with toes to having hooves, better suited for running in their habitat.
Horses do not have horns (Unicorns are mythological creatures) are you thinking of cow horns (in which case no they do not have to be clipped), or perhaps horses hooves? If you are thinking of horses hooves, then the horn on these is the same as your fingernails and it grows slowly. In the natural state the horse will wear its hooves down by running but in domestication this may not happen and a farrier or blacksmith needs to come and file the hooves periodically. This is normally done when the horse is being fitted for new horseshoes. If the hooves are not kept filed (or worn down naturally) hey will grow to the point where the horse can no longer walk and this is very painful.
no horses do not have split hooves but scientist believe they did at one time but now heir hoves are pure solid and roundish
Just because the horse it a quarter horse this means nothing when it comes to shoeing a horse. It all depends on the horses hooves (how healthy they are) and what the horse is being used for.
The time when a horses hooves will be driest depends more on the climate than what time of year it is. If the climate is dry and there is no moisture on the ground then it's likely that the horses will dry out more than if it were raining or if a wet spot was provided.
You do not have to shoe your horses. You can have a natural hoof care specialist come to ur farm to trim your horses hooves, but not put shoes on them (Because they are not having nails hammered through their hooves, which creates lots of holes). This is not only better for your horses hooves, but it is a lot cheaper too.
because they change over time
I believe it would be great to be able to run across open prairie and have no fence to stop you. I also think the life of a wild horse can be very hard, like avoiding predators and round ups, but nice to be in the company of others the whole time. no one really knows for sure.
Well most of the time horses are bigger than dogs. Horses have hooves and dogs feet have pads. Horses have manes and a coat of fur where as dogs just have a coat of fur. Horses eat horse feed and dogs eat dog food.
Hoof grease or conditioner can be used occasionally to maintain hoof health by moisturizing and protecting the hooves from drying out or cracking. It is recommended to consult with a farrier or veterinarian for guidance on when and how to properly apply hoof grease based on the specific needs of your horse.
