Anywhere from six to twelve months — the research on this breed found close to nothing, so the date is genuinely yours to choose. Which leaves room for the thing that will actually make a difference to his next fifteen years, and it costs about twenty dollars.
The timing half of this is short, so here it is. The Yorkshire Terrier comes out of the big neutering study looking almost boringly healthy — no joint disorders worth noting, cancers at about one percent, and no increase from neutering at any age. The paper's guidance is simply to pick the age that suits you, and I agree with it.
One thing before the rest: this breed is prone to a liver condition that matters a great deal on the day of any anaesthetic, and I go through it properly on the female page. It applies to him just as much. Read that section before his surgery.
With the date settled, here is what I would actually like you to take from this page, and it has nothing to do with surgery.
Take the collar off him and put him in a harness. A Yorkshire Terrier's windpipe is the weak link in this breed, and years of a small dog pulling against a narrow collar is pressure applied to exactly the wrong place.

The one change worth making
A dog's trachea is held open by rings of cartilage, rather like the ribbed hose on a vacuum cleaner. In the toy breeds, and in Yorkshire Terriers particularly, that cartilage can soften over the years so the airway flattens as he breathes in. It is a slow, chronic problem rather than a sudden one, and it tends to declare itself in middle age.
What it sounds like: a dry, honking cough — people describe it as a goose honk — typically triggered by excitement, exercise, pulling on the lead, or pressure on the throat. In an established case a dog may cough after drinking or when picked up around the chest.
What you control: not the cartilage, which is largely how he was built. But you do control how much repeated pressure that area takes, and how much weight he carries. Those are worth having.
None of that requires surgery, and all of it compounds over a fifteen-year life. Neutering him at eight months instead of eleven will not matter. This will.
The other thing that shortens toy-breed lives
If the windpipe is the first thing I would change, dental care is the second, and it starts younger in this breed than most owners expect. A Yorkshire Terrier carries the same number of teeth as a Labrador in a jaw a fraction of the size, so they crowd, plaque packs into the gaps, and gums recede early. By the time a dog is visibly reluctant to eat, the disease is usually advanced and has been painful for a while.
While he is asleep for his neuter I will go through his mouth properly and remove retained baby teeth if he still has them — where an adult tooth is coming in alongside a deciduous one that should have gone, that gap is where trouble starts. Dealing with it while he is already under saves a second anaesthetic. After that the answer is unglamorous: brushing, a few times a week, started young enough that he accepts it as normal. It is worth more than anything else on the shelf.
What I recommend
On the last point, undescended testicles are disproportionately common in the toy breeds and it is the one thing here that genuinely changes the plan. If it has not come down by six months it is not going to, and a retained testicle carries a substantially higher risk of becoming cancerous while being impossible to monitor by feel. That gets its own timetable.
If you have a female Yorkie too, hers runs on a different clock — she has mammary-tumour protection to gain by going early. That is on when to spay a Yorkshire Terrier, along with the liver screening that applies to both of them.
What the day looks like
A neuter is the shorter and simpler of the two surgeries — the testicles are external, so it is one small incision just in front of the scrotum. That is also why there is no laparoscopic version worth offering, unlike a laparoscopic spay where the alternative is a long abdominal incision.
He comes in after a shorter fast than you may have been told, has pre-anaesthetic bloodwork and an IV catheter, and is monitored continuously on a warming system — a dog this small has almost no thermal reserve, his glucose is watched, and his drug doses are calculated rather than estimated. I do the surgery myself; I have been a solo veterinarian since 1998. He goes home the same day with pain medication, and while he is asleep I will check his mouth. More on the day itself is on what to expect from your pet's surgery.
Yorkshire Terrier neuter questions
Because his windpipe is the weak link in this breed. A dog's trachea is held open by rings of cartilage, and in the toy breeds — Yorkshire Terriers especially — that cartilage can soften and flatten over the years, so the airway partly collapses when he breathes in. The classic sign is a dry, honking cough that sounds like a goose, usually worse when he is excited, pulling, or being lifted by the collar. A dog who spends years pulling against a narrow collar is applying repeated pressure to exactly the wrong place. A harness moves that load onto his chest. It costs one purchase and it is the single most useful thing most Yorkie owners can do.
Six to twelve months suits most families and there is no penalty on either side. This breed's findings in the big neutering study are close to the quietest in it — no joint disorders worth noting, cancers around one percent, and no increase from neutering at any age — so the study leaves the age up to you and I am not going to invent a reason to override that. What tends to decide it in practice is whether he has started marking indoors and whether there is an intact female in the house.
Often yes, and considerably more reliably if you act while the habit is new. Marking that has gone on for a year or more can persist afterward, because by then it has stopped being purely hormonal and become learned. Small dogs are frequent offenders and it is one of the most common reasons families ask me to bring the surgery forward. That is a fair reason — a dog who is succeeding in his home matters more to me than an age on a chart.
Not in the way most people mean. It reduces roaming, marking, mounting and some male-to-male tension. It does nothing at all for barking, which is what Yorkie owners usually want addressed, and nothing for the general conviction that he is a much larger dog than he is. That is terrier, not testosterone — this breed was developed to go into places rats lived and deal with what it found there, and the surgery does not edit that out. Training and exercise will do far more for you than an operation will.
It is, in my view, the thing most likely to shorten his comfortable life, and it starts younger than owners expect. A Yorkshire Terrier carries a full set of teeth in a jaw a fraction of the size, so they crowd, plaque packs into the gaps, and the gums recede early. By the time a dog is visibly reluctant to eat, the disease is usually well advanced and painful. So while he is anaesthetised for his neuter I will look at his mouth properly and deal with retained baby teeth if he still has them. After that, the boring answer is brushing — genuinely, a few times a week from a young age is worth more than anything else you can buy.
Yes, and undescended testicles are disproportionately common in the toy breeds. A testicle that stays inside the abdomen sits at body temperature rather than a few degrees cooler, which carries a substantially higher risk of it becoming cancerous later, and it cannot be monitored by feel. If he is past six months and it has not come down, it is not going to. That gets scheduled on its own timetable rather than waiting for a convenient age, and it is a slightly more involved surgery than a routine neuter because I have to go and find it.
