Ok so I brought this stud colt home yesterday, he is supposed to be two years old but I don't think he is, i think he is a yearling, I think he should have dropped already.

My question is, if he has been cut, how can i tell? or do i have to get a vet out?

If he hasn't dropped by a year I would be concerned. I would get a vet out and IF he hasn't dropped, then it is surgery. You don't want a stallion for breeding that hasn't dropped by a year. If you bought him for breeding purposes, I suggest you get your money back.

I think you should get a vet out to check. Second, not all colts drop by two years..my colt is turing two & hasnt dropped so we must get it removed through a different method.

I fully agree with LHCHAMP.

If he has been cut he will just have an empty sac of skin, and you should be able to see a scar if he's been cut. Lol, that all depends on how close he lets you get to his daddy parts though. The testicles go up and down a lot in the first few years. How is the weather in Arizona, still a little chilly? If so, when it's cold their testicles will be snugged up for warmth. Sometimes they're just high and smaller. How tall is this colt? Maybe find a diagram for teeth and see which teeth he has? Do you know if he's had wolf teeth removed?

Ditto to what Jen said. Yes they can certainly pull them up especially when it gets cold. You should be able to tell though if he has been castrated. If he has his man parts pulled up, there will still be a wideness there if he has not been castrated (from inside hind leg to other inside hind leg) and if he has been castrated, there should be just two narrow folds/slits of skin behind his sheath that are so close together that they almost or, do touch.
