my friend by accident blew a fire extinguisher in my face and Im wondering how quick side effects take to set in and what i should do if i breathed it in.
Veterinarians will often refer to each of these conditions as a Unilateral Cryptorchid (one testicle is inside) and Bilateral Cryptorchid (both testicles are inside). They also sometimes call them 'rigs'. Testicles that have not dropped are prone to tumors and other nasty problems. You should probably have your vet come out and take a look at them to see if there may be underlying issues and to discuss possible options for correction. I highly recommend keeping them away from your mares. Though it is 'unlikely' that they can produce with a mare - cases HAVE been documented where it has happened; even with seemingly gelding-like behavior.
if you use it off road i wouldn't put more than 1 spacers on it with aftermarket studs. i recommend going with a wheel with a deeper off set or adjust the steering stops so it won't turn sharp enough to get in to the torsion bars.
