This usually a job for a qualified veterinarian.
The sole may have to be opened to drain the abscess and then bandaged to prevent reinfection until it heals.
Some folks make a poultice for the foot the help draw out and heal the abscess.
There are commercial preparation and poultice boots available at most tack stores.
If it is making the horse lame, than it is probably a big deal (ps CALL THE VET!) if not, dont worry about it and yes it can be called an abscess.
It could be a hoof abscess, or another type of injury, or laminitis. Lameness can be serious...have a vet look at the horse.
This can vary widely - from a few days to a few weeks, depending on the nature of the wound and the amount and location of the infection. Because the infection cannot drain out at the wound site on the sole of the hoof, the pus (infection) will follow the path of least resistance and travel up into the hoof until it drains (blows out) at the coronary band. This can sometimes take awhile and your horse will be in pain, often severe pain, until it happens. Rather than wait for the abcess to blow out, it is actually better if your farrier or vet assists by cutting down into the sole of the hoof and paring out the tract with a hoof knife, allowing the infection to drain out from the sole (bottom) of the hoof. This will speed healing and give your horse almost immediate relief by relieving some of the pressure the infection was causing deep in the hoof.
Foot is to man as hoof is to horse. Both are parts of the respective animals that they use for movement.
You call a veterinarian who specializes in horses. If you try to treat it yourself it is likely to end badly. The vet will drain the abscess and administer an appropriate antibiotic.
The horse's hoof has an infection. Do not ride the horse but call your farrier.
Black horn is the dark pigmented hoof, whereas, a white horn is the light colored hoof. Where a horse has white socks, the hoof will be white also.
A horse's foot is called a hoof. The plural (or when referring to all feet) is hooves.
The horse does have a frog on their hoof except it is not the real animal. It is a part of their body/hoof.
A graze just above a horses hoof.
The periople is the clear covering of the hoof wall.
