We neutered our Westie Sami at the age of six. Not as a puppy, not on the schedule most vets suggest, and not without a lot of back and forth first. This is the full story - how we decided, what the surgery day actually looked like, why we chose a recovery suit over the cone, and how his recovery went week by week.

One thing before we start: this is our experience as owners, not veterinary advice. Your vet knows your dog; when in doubt, ask them.

Deciding: Why We Waited Until Age Six

The honest answer is that I wanted Sami puppies. For the first years of his life I thought we would breed him, and that our next Westie would be his puppy.

When Sami was around six months old, I looked into neutering properly. The case for it is real: no more risk of testicular cancer, much lower risk of prostate problems later. But some studies also suggest that keeping a dog intact has benefits - testosterone helps build muscle and keeps them active, and early neutering can affect their hormones in ways that aren't all positive.

Sami's vet gave us a middle path. She recommended neutering in general, but said that if we wanted puppies, we could leave him intact and do the surgery later, around age 7 or 8. The latest she'd want to do it is around 10, because anesthesia gets riskier as they get older.

The puppies never happened. Where we live in Portugal there aren't many Westies, and I couldn't find anyone with a female available for breeding. Then his skin allergies started around age two, and someone pointed out that allergies can be genetic. Breeding a dog with that many allergies didn't feel right, so that settled it.

What Finally Made the Decision

For years, neutering just wasn't a priority. We did annual bloodwork and ultrasounds, so I knew he was healthy and that we'd catch any problem early.

Then, during an ultrasound for an unrelated stomach issue, the vet found a small cyst on his prostate. Half a centimeter, nothing to panic about. But she was clear: these cysts will keep appearing in an intact male, and in the long run they can lead to prostate cancer. Removing one cyst doesn't stop the next one. Neutering does.

That was the moment the abstract pros-and-cons debate became a concrete decision. We booked the surgery.

Living With an Intact Male: What It Was Actually Like

Since so many people ask whether leaving a male dog intact causes behavior problems, here's our honest experience.

When Sami was young, I worried he'd become aggressive or start humping everything. His trainer told me something I never forgot: an intact dog that is trained will be calmer and better behaved than a neutered dog that is not trained. Six years later, he was mostly right. Sami is calm because of his training. He never humped legs. He doesn't guard food or toys from us.

But there were real downsides. He marks constantly on walks - three drops here, two drops there, every five steps. A five-minute walk is never enough because he needs twenty minutes to get everything out. I keep the hair on his belly clipped very short because otherwise it stays smelly and stained. And he has a reactive streak with other males - about half the time we pass a male dog, especially a bigger one, he'll lunge and bark like he's twice his size. Some of that is terrier attitude, but being intact definitely plays a part.

The Night Before Surgery

The vet's instructions were simple: no food after 9 pm, no water from bedtime on. We pushed his dinner as late as allowed so he wouldn't be starving by morning, then picked up every water bowl in the house - one in the kitchen, one in the bedroom. He was not impressed.

The hardest part of the morning was me, not him. Making coffee without reaching for his breakfast took actual willpower, and he sat there doing his best hungry-orphan act. His daily heart pill was allowed - just no food, no water. Interestingly, once his usual breakfast window passed, he seemed to forget about food entirely and napped until we left.

Surgery Day

First step at the clinic was bloodwork to confirm he was fit for anesthesia. Sami was so stressed that the blood wouldn't flow properly into the syringe - the vet only managed once I leaned in and started kissing his head. Make of that what you will; I found it equal parts funny and heartbreaking.

The bloodwork came back perfect and he went in. The surgery itself took about two hours including prep and wake-up. Since he was already under, we asked for a dental cleaning too - if your dog is having anesthesia anyway, it's worth asking about, because dental disease is one of the most common issues in small breeds.

The vet let us sit with him in the recovery room while the anesthesia wore off. He was wobbly, spaced out, and desperate to leave, but within half an hour he was walking and peeing normally. We paid 225 euros for everything - surgery, medication, and the dental cleaning - here in Portugal. Prices vary a lot by country, so treat that as one data point, not a benchmark.

The Checklist I'd Hand a Friend

If someone I know were neutering their Westie next week, this is the prep list I'd send them:

Book the surgery for a stretch when someone can be home for the first two or three days. Confirm the fasting instructions with your own vet - ours was food cut off at 9 pm, water at bedtime, but clinics differ. Ask whether any daily medication is still allowed in the morning (Sami's heart pill was). Order the recovery suit a week ahead so you can check the fit, and keep a cone as backup. Ask about adding a dental cleaning while they're under. And ask, before you leave the clinic, what the warning signs are and which number to call if you see them - it's much easier to hear that list calmly in daylight than to search for it at 2 am.

Surgery Suit vs the Cone of Shame

Skip the cone if you can. We bought a dog recovery suit instead - a soft bodysuit that covers the wound - and it was one of the best decisions of the whole process.

With the suit, Sami could eat, drink, and sleep normally from hour one. No bumping into door frames, no taking a cone off and putting it back on at every meal. He wore it for four days and barely seemed to notice it.

Two practical notes. First, sizing runs large - Sami's suit kept slipping down his back paws and tripping him, so I made some very untailor-like adjustments with a needle and thread to shorten the legs. If you can, size down or pick a brand with adjustable fit. Second, keep a cone on standby anyway. We kept ours next to the bed in case he started licking at night, and never needed it.

Recovery, Week by Week

Day 1 (surgery evening). Food and water allowed again from 8 pm - small portions of soft food only. He'd gone almost 24 hours without eating and inhaled his tiny dinner, then licked the bowl hoping for a miracle. The vet sent us home with a painkiller for the next day and an anti-vomiting pill just in case. He slept through the night in his bed placed between us, so we could catch any midnight licking attempts.

Day 2. He woke up belly-up and without a care in the world, then ran into the living room and jumped on the couch like nothing had happened. Walks were normal from the very first morning - outside, terriers seem to forget anything is bothering them. We cleaned the wound once with antiseptic diluted in a little water, per the vet's instructions, and after that left it alone to heal.

Days 2-5. Three smaller meals a day instead of two, with antibiotics and anti-inflammatories mixed in at set times. He considered the extra mealtime a personal victory. We watched him constantly the first couple of days - taking turns even for bathroom breaks - but he never once tried to bother the wound.

Day 4 onward. The suit came off for good. He slept a bit more than usual the first days, which is normal after anesthesia, but by the one-week mark he was completely back to himself. We did this five days before Christmas expecting to spend the holidays nursing him, and instead we were visiting friends on Christmas Day with a perfectly normal dog.

Did His Behavior Change?

Everyone told me not to expect much from neutering an adult dog, because the habits are already formed. Two months in, that was mostly true. The marking didn't disappear, and the occasional toy-humping is apparently a lifetime membership. What I did notice was a slightly calmer edge around other male dogs. If you're neutering an adult expecting a personality transplant, you'll be disappointed. Do it for the health reasons; treat any behavior changes as a bonus.

When to Call the Vet

Before we left the clinic, I asked exactly what would count as a red flag during recovery. Her list, plus what I'd add from experience:

Refusing food, refusing to walk, or standing with a hunched posture - any of these in the days after surgery means call the vet. Vomiting more than once. Any redness, swelling, discharge, or opening at the wound site. Extreme lethargy beyond the first two sleepy days. And trembling is normal right after anesthesia, but not days later.

None of it happened for us. But knowing the list ahead of time made the whole recovery much less stressful.

Was It Worth It?

Yes. The thing I'd tell my past self is that the decision was harder than the event. The surgery was routine, the recovery was easier than expected, and the prostate worry is now off the table for good. If your Westie is intact and getting older, talk to your vet about timing - waiting was right for us, but waiting forever wasn't.

Neutering also shifts what your dog needs from you as they age - metabolism slows a little, so watch the portions. Our senior Westie care guide covers what changes after age 8, and the Westie health problems overview has the full screening schedule by age. Weight matters even more after neutering - the Westie weight guide shows how to check yours at home.
