Regular trimming of your donkeys hooves are required for good hooves. All donkeys feet grow at different rates and their diet can change the growth rate of their hooves. If you have a donkey I would ask the ferrier or vet next time he comes.
No, your horse's hooves should not hit themselves. Accidents can happen of course, but if this happens often, it is usually a sign that the horse either needs his hooves trimmed, or that he has a conformation defect that is preventing his feet from traveling straight.
In the wild a horse or donkey will wear his hooves down naturally. Once the animal has been rescued and is being held in large corrals or holding pens, they aren't wearing the hooves down enough and so they must be trimmed about every 6-8 weeks.
Cloven hooves is a evolutionary process with the only possible explanation being because they live in a variety of environments that needs them to have two hooved toes to grip a surface that a horse's hoof could have trouble with. Other than that, there really is no real explanation.
A farrier also trims horses' hooves, evaluates their gait and hoof health, advises on proper hoof care and trimming schedules, and may provide corrective shoeing or therapeutic treatments for hoof conditions. Some farriers also work closely with veterinarians to address lameness issues or provide input on overall horse health related to the hooves and lower limbs.
A farrier also called a blacksmith or a podiatrist
You hire a farrier; a certified person who is trained to trim and shoe horse's hooves. You can also do it too if you go to school for it.
A flying donkey of course
You don't need to wait for a goat to fall asleep to trim its hooves. You just need two people - one to hold the goat in a standing position and the other to lift each hoof and trim it.
When you trim their hooves ie cut their toe nails.
Most kinds, yes, but lamas don't have hooves, they have toenails. I prefer small horse hoofnippers to do the job, and general trim the nails every couple of months.
The average farrier rates are: $30 for a trim, $60 to shoe only 2 hooves and $90 for all 4 hooves to be shod.
Trimming and filing should begin at exactly one month of age for a foal.
Depending on the type of surface on which they are grazing you may need to trim their hooves occasionally.
Donkey.
Yes. These are needed because of a donkey's "tough" behaviour. Refer to the Related Link for proof (see anatomy).
Yes they do grow throughout the donkeys life
In domestication horses need their hooves trimmed to keep them a proper shape to avoid lameness. In the wild horses 'trim' their own hooves by walking on rough ground which wears them down.
