I am new to the world of horses. I am almost at retirement age, and got my first horse a year ago. I fell in love with a horse down the street from us, every time I would jog down our road, one of the horses came up to meet me & I got "hooked", so we purchased a mare lat year & really love her!! My question is, she is 9 years old & I am in the position to where I can afford to board another horse, so why would I not breed her & raise a little colt, of filly? Do you have to have the vet involved? Can you not just put them in a field with a stud??
