It wasn't too long ago that a 15-year-old horse was widely considered to have entered the senior realm. But today, horses are living well into their 30s—and beyond!—on a regular basis. And if you were to ask 10 owners or equestrians what they consider old for a horse and why, I bet you'd get 10 different answers. In my humble opinion, I don't think you can judge a horse's age solely on how long they've been on the planet.

If a beginner has to choose between a stallion and a gelding, the gelding is by far the safer and wiser choice. Besides making a safer, quieter and more well-behaved riding horse, gelding serves as an effective way to avoid unwanted offspring and ensure that only the best horses are kept for breeding purposes.

The benefits of gelding young. Many owners are now gelding colts younger for good reasons; most importantly, they realise that the smaller the testicles, the smaller the operation and the easier it is on the horse. Another step in the right direction is to geld a colt before weaning.

When you are looking for your first horse, you might wonder, should you buy a gelding, a stallion, or a mare? Certainly, it’s unlikely a stallion would make a good beginner horse. There are a few rare circumstances when a beginner might ride a stallion. Very high-end riding stables might put a beginner on a stallion in a very controlled environment.

In times past, before modern veterinarian medicine ensured gelding was done properly, a horse left with some testicular and epididymis tissue may have exhibited stallion-like behavior. This is where the term ‘proud cut’ comes from. Today, it’s unlikely you will find any truly ‘proud cut’ geldings.

When choosing a gelding, there is one thing a buyer has to watch for and that’s a ridgling. If a horse is very stallion-like in its behavior but appears to be a gelding, it may be something called a rig, or ridgling.

A gelding is a castrated male horse, donkey or mule. Unless a horse is to be used for breeding purposes, it should be castrated. Gelding can make horses more even tempered and easier to handle. A stallion who is gelded later in life may retain more aggressive stallion-like behavior. A colt may be gelded before it is one year old -- as soon as the testicles descend into the scrotum.
