shoeing my horse

I am not sure if I should shoe my horse (Milkshake). I will competing her in jumping, western pleasure, barrel racing and I think that is all. I am not sure if I should shoe her or not

Ask your farrier. Depending on the work schedule the horse will be on and what type of footing will determine if shoes are in order. Also another thing is if your horse has strong hooves in good condition.
Your farrier will be able to give you the recommendation needed for your area :)

A good farrier should be able to tell you. It depends a lot of factors like if the hooves are being worn down faster than they are growing.

A lot of people say that barefoot is the way to go, but Mudpie is a tenderfoot and he actually goes immediately lame without them. For about a year and a half, he had to have leather rim pads on his fronts, but we didn't put them on this time since he's not working (injury) right now and he's doing fine(:
