What are the 4 benefits of horseshoes?

Protects from excess wear, provides traction, correct stance or gait, assist pathological conditions (i.e. navicular disease, injury, etc.)

What is hot shaping?

Shape of the shoe - with use of heat.

What is cold shaping?

Shape of the shoe - without the use of heat.

What is hot fitting?

Placing the shoe on the foot while hot to help fit. Makes foot fit shoe!

What is cold fitting?

Placing a cold shoe against the foot and sizing by manipulating the shoe. Makng shoe fit the hoof!

How does a horseshoe size?

Increases by length of steel and width at the heels. Size varies by companies.

What is horseshoe size affected by?

Length of the foot, width of the heels and the position of the heel nail hole.

What are different shoe materials for horseshoes?

Steel, aluminum, titanium, plastic and rubber.

What is the purpose of nails?

Designed for use with horseshoes; designed to bend.

Sizes in nails vary by what?

Length and width.

Why should you use the smallest nail possible when shoeing a hoof?

Because otherwise huge, uncesscary nails will leave big holes in your horses foot. Could potentially leak to cracks.

How should the shoe fit the foot?

From the toe to the widest part of the quarters, they should be flush!

Why should the heel of the shoe extend slightly beyong the natural heel?

For support!

Where should nail placement occur?

Should be 3/4 to 1" above the ground surface of the shoe. SHOULD BE IN LINE!

Where in terms of the white line should the nails be placed?

The outside of the white line.

Where should nails never be placed?

The heel area.

What is quicking?

Nail penetrates the sensitive structures. Usually involves bleeding and should be treated like a puncture wound.

What is a "close" nail?

It puts pressure on the sensitive structures.

What do pads provide? (5)

Protection, traction, angle (wedge), cushioning and weight.

If you are going to use pads, what do you have to do to the hoof?

Pack it!

What is the purpose of quarter clips?

Holding the shoe on fit.

What are some examples of tractiond devices?

Borium and heel calks. They add traction and grip.

If the traction device grips harder and longer, the stress is...?

Greater!

What are extended heels used for?

More support.

What are trailers used for?

Same as extended heels, except the heels are turned out for additional length and wider support base.

What is a rolled toe?

Allows breakover to happen faster.

What is a rocker toe?

Shoe is bent upward.

What is a square toe?

Toe shape of shoe is straight across. More severe.

Why is the square toe not appropriate for every horse?

Because it forces breakover to be in the center of the foot.

What is the purpose of a straight bar shoe?

helps to equally distribute weight and support heels.

What is the overall purposes of bar shoes?

shifts weight bearing and relieves pressure.

What is the purpose of an egg bar shoe?

Provide a lot of support. Common with navicular disease.

What is the purpose of a heart bar shoe?

Puts pressure on frog, provides support on under of foot. Common to see with horses that have foundered.

What is the purpose of a full support shoe?

Combination of an egg and heart, typical to see with horses that have underslung heels.

What is the purpose of a mushroom bar shoe?

Relieves pressure from heels. Common to see with horses that have sidebone. cannot be ridden.

What does corrective shoeing do?

Corrects stance or gait.

What does theraputic shoeing do?

Deals with pathological conditions.

When should corrections of stance be made?

Before the growth plates close.

When should foals be evaluated?

4wks old.

Rotations do NOT respond to what?

Trimming or surgery!

What is periosteal stapling?

Staples are placed on the "fast" growing side of a joint to retard growth and allow other side to catch up. "The old fashioned way!"

What is periosteal stripping?

An incision made in the periosteum of "slow" growing side of a joint to stimulate growth and allow it to "catch up" with the opposite side of the joint.

What would you use to correct the stance of a cowhocked horse?

Trailers.

What would you use to correct stance of a horse that has sloping pasterns?

Extended heels or egg bar.

When a horse interferes, how is one supposed to change the gait so the interference no longer happens?

Speed up the font feet or slow down the back feet. But NOT both!

How would you speed up the front?

Short toe, rolled toe, rocker toe, square toe.

How would you slow down the hind?

Egg bars, extended heels, keeping a long toe.

What are the 3 principles of theraputic shoeing?

Protect the foot with a pad or shoe. Support the limb or foot. Shift weight distribution.

How would one treat laminitis/founder?

Heart bar, rolled toe, rim pad.

How would one treat navicular disease?

Egg bar, wedge pad, rolled/rocker toe.

How would one treat sidebone?

Rim pad, rocker/rolled toe, mushroom bar!

A study was done with 12 horses, some with wedge pads and some without, how did the study turn out?

The wedge pads significantly decreased shock in comparision to the horses with no wedge pads.

Why would glue on shoes be used?

Chronic hoof wall injuries, thin hoof walls, poor hoof wall strength, and hoof is too short.

What are reasons to use glue on shoes?

Laminitis, surgicial ressections, hoof wall injury, white line diease, coffin bone fractures.

Why type of materials are used to reshape and repair the hoof wall if damaged?

epoxy, acrylic and even fiberglass.

Why should you NEVER use hoof dressing if you are using an acrylic, epoxy or fiberglass to reshape and repair a horses hoof wall?

Because the hoof dressing could have negative effects with the material used to do its job, and end up deteroating it, damaging it, weakening it, etc.
