Pros and Cons of Neutering a Yorkie: When To Do It?

We all know that these are one of the tiniest dogs in the world, so deciding when to neuter a Yorkie can be daunting. Neutering (castration for males) and spaying (ovariohysterectomy for females) are common procedures with clear benefits.  However, they also carry some downsides. 

In this post I’ll share what I’ve learned – both from vets and from my own experience with my little Yorkie – about the pros and cons of neutering a Yorkie. 

We’ll cover health effects, behavior changes, timing, and how to care for your pet after surgery (post-surgery care). 

Why Neuter Your Yorkie? (Benefits)

Neutering a Yorkie has several major benefits for health and behavior. For one, it prevents unwanted pregnancies and eliminates reproductive cancers. A neutered male Yorkie cannot father puppies and no longer faces testicular cancer. Besides, his risk of prostate disease is greatly reduced. In fact, studies note that neutering “eliminates the possibility of testicular tumors and reduces the risk of prostate disease” in dogs.

Neutering also tends to curb mating-related behaviors. For females, there are no more heat cycles (no bloody discharge or attraction of male dogs), which many owners find a relief. 

For male Yorkies, neutering often means less roaming and territory-marking. Male dogs can smell a female in heat miles away.  So, it’s not surprising that intact males often try to escape or mark. After neutering, these urges drop. 

By neutering your Yorkie, you’ll prevent urine-marking behavior and reduce their breeding instinct. Many owners say that their dogs became less obsessed with neighborhood bitches in heat once he was neutered. Their wanderlust and marking both declined noticeably.

Other advantages include overall lifespan and population benefits. Neutered dogs tend to live longer on average (since they avoid cancers and infections), and spaying/neutering helps prevent accidental litters and lowers pet overpopulation. (Millions of dogs are euthanized in shelters each year from unplanned litters.) 

Cons of Neutering a Yorkie (Risks and Downsides)

No medical procedure is entirely risk-free, and neutering a Yorkie has some potential downsides to consider. Major concerns include surgical/anesthesia risks, and a few health or behavior changes post-neuter:

Anesthetic/surgical risk

Any anesthesia has a small risk of complications or death. For dogs, the risk of death from general anesthesia is about 0.17%, or 1 in 600. Yorkies are small, so vets take extra care (e.g. warming blankets, blood pressure monitoring) to minimize risks. Still, there is always a chance of anesthesia reaction, hypotension, or hypothermia in tiny pups. In real life, serious problems are rare. However, I felt anxious before my puppy’s surgery. Good preparation and an experienced vet really help.

Urinary incontinence (females)

Spayed females can develop a “leaky bladder” later in life. Roughly 20% of spayed female dogs eventually show some incontinence (mostly when lying down). Waiting until your Yorkie is a little older (some say ~3 months old or more) can lower this risk. It’s a real downside to note: many owners end up needing doggy diapers or medication for leaks years after spay.

Possible increased certain cancers or bone issues

Some studies suggest that spayed/neutered dogs have slightly higher risks of certain cancers or orthopedic problems. For example, there is debate about neutering increasing risk of osteosarcoma (bone cancer), bladder cancer, or lymphoma. Removing sex hormones can delay the closure of growth plates. This means the dog might grow a little taller or have weaker joint cartilage. However, these effects are usually small and often found in larger breeds. Most research shows that small dogs, like Yorkies, do not have big increases in joint or cancer problems after neutering.

Weight gain

Metabolism can slow a bit after neutering. Many neutered dogs (Yorkies included) tend to gain weight if diet and exercise aren’t adjusted. So you’ll need to watch portions and activity to keep your Yorkie trim. Try not to overfeed your pooch with rewards and separate a certain amount of food for snacks. That’s how you’ll control calorie intake.

Behavioral change

While many sexual behaviors are reduced, neutering is not a cure-all for bad habits. A neutered Yorkie might still bark, have anxiety, or be energetic; it just won’t have the hormone-driven urges as much. In rare cases, a male or female might actually become slightly calmer or even more prone to anxiety post-neuter – every dog is different. But in general, the most predictable changes are reductions in mating behaviors (roaming, marking, mounting), not major personality shifts.

When to Neuter a Yorkie?

Timing matters. The traditional recommendation for toy breeds like Yorkies is to neuter or spay by around 6–9 months of age, but practices vary. It much depends on the dog’s weight, and appearance. In other words, if you own a teacup or miniature Yorkie, then your vet will recommend you to wait until your pooch matures a little bit. 

Generally, vets today suggest tailoring it to each dog:

• Males: For male Yorkies, testosterone-driven behaviors often kick in by 6–9 months. Neutering around that time usually works well to curb these behaviors. Some owners wait until their Yorkie has nearly finished growing (around 8–12 months), but small dogs typically don’t need a late-neuter like giant breeds do. The AKC notes that delaying neuter in large breeds can protect joints, but for small dogs (under ~45 lbs) early neutering didn’t show extra risks. In practice, neutering a Yorkie around 6–9 months is common.
  
• Health/Weight/Development: If your Yorkie was very small or sickly as a puppy, your vet might wait a bit longer (to ensure safe anesthesia). Conversely, if he’s very active in roaming or a female starts hormonally erratic behaviors early, you might spay/neuter earlier. Always base the decision on your dog’s growth, breed, and vet’s advice.

Do Yorkies Calm Down After Neutering?

A very common question! Neutering does often affect behavior – especially behaviors tied to hormones. Typically, younger dogs tend to “calm down” somewhat after spay/neuter if they were driven by mating urges. So if your male Yorkie was aggressively chasing female dogs or constantly marking territory, he’ll likely mellow a bit. My energetic terrier certainly stopped trying to bolt out the door during another dog’s heat after he was neutered.

However, neutering isn’t magic. If your Yorkie is naturally playful, barks a lot, or has separation anxiety, he will probably still act like that, just without the sexual drive. Many neutered dogs are still high-energy – they just might be a more “social” energy instead of “sexual” energy. In other words, neutering often stops specific reproductive behaviors, but doesn’t guarantee your Yorkie becomes a couch potato. Each dog is different. A small study noted small dogs don’t show large changes in temperament post-neuter. They usually just lose the urge to “find a mate.”

Yorkie Breeding and Pregnancy

If you plan to breed your Yorkie, then neutering/spaying is obviously off the table. Breeding Yorkies should be done carefully with health checks, pedigree knowledge, and ideally professional guidance – accidental litters are not advisable. For perspective, a pregnant Yorkie is no small affair: they carry the entire pregnancy for about 63 days, usually delivering 2–4 puppies (some litters can be 1 or as many as 5). You can read more about Yorkie pregnancy and litter sizes in our article How Many Puppies Can a Yorkie Have?.

If you do not want to breed your Yorkie, neutering is the best way to avoid an unplanned pregnancy. A female Yorkie can get pregnant at her first heat (as early as 6 months old), and even a tiny surge of sperm can lead to a litter. Similarly, an intact male Yorkie can impregnate any unspayed female it encounters. (In fact, male dogs can smell a female in heat from miles away.) So for most pet owners who aren’t professional breeders, preventing any mating – by spaying or neutering – keeps life simpler and less stressful.

Aftercare: Caring for Your Neutered Yorkie

After the surgery, your Yorkie will need tender loving care. The first 1–2 days are the most critical. Expect your pup to be groggy and disoriented from anesthesia – he may even vomit a little after coming home. According to vets, you should keep him rested and quiet for at least 24–48 hours. For the first night, limit food and water: offer only a quarter to half of his usual amount at dinner to prevent nausea, then monitor him closely overnight. (He should be somewhere you can watch him – no unattended yard time on day one.)

Rest and quiet:

Confine your Yorkie to a small area or crate when you can’t supervise him. This prevents him from jumping on furniture or chasing cats. Use a harness for bathroom breaks (avoid collars that pull on the neck). It’s often helpful to give him an extra-soft bed or cushion to lie on – Yorkies have tiny joints, and a supportive bed can help ease any soreness. In fact, our store offers specialized cozy beds (like memory-foam or snuggly donut beds) designed for small dogs; these can provide comfort and reduce joint pressure during recovery.

After surgery, your Yorkie will need a soft, supportive place to sleep. A good dog bed – such as the padded Yorkie beds available at Yorkies-Gram – helps keep her comfortable and immobile. Yorkie-specific beds are made to support their little bodies and joints, reducing pressure and pain. I recommend putting the bed in a quiet corner where your pup can rest undisturbed for the next week or two.

Incision care:

Check the surgery site daily. Some bruising or slight swelling is normal, but keep an eye out for redness, oozing, or if your Yorkie yelps at the area. Do not apply any creams or sprays unless your vet instructs you to – these can irritate the incision. Keep the area clean and dry. Initially, there’s no need to bathe your pup. In fact, don’t bathe or swim him until the vet gives the all-clear (usually after stitches are out, ~10–14 days).

E-collar (cone):

It’s very important your Yorkie doesn’t lick or chew the stitches. Even a few licks can cause infection. Vets strongly recommend using an Elizabethan collar (E-collar) or recovery cone right after surgery. Keep the collar on 24/7 until the vet okays its removal – only take it off if you can watch your dog every second. There are even soft or inflatable collars available that can be more comfortable for Yorkies. Without it, your Yorkie’s natural grooming instinct could open the wound!

Exercise restriction:

Limit activity for about two weeks. Short leash walks to potty are fine, but no running, jumping, or rough play. Most vets recommend keeping the dog confined in a small room or crate except for bathroom breaks. This prevents the incision from tearing open. If your Yorkie is very small, it’s even helpful to carry her up and down stairs to avoid strain.

Diet and hydration:

Continue giving only a small meal the night of surgery (as above). The next day, you can resume a normal diet, but keep an eye on appetite and thirst. The vet may have sent home pain medication (often an NSAID) to keep your Yorkie comfortable. Make sure to give it exactly as directed; do not use human painkillers. After neutering, dogs often feel more relaxed and may gain weight faster, so measure food to maintain a healthy weight.

Signs of trouble:

Know when to call the vet. If you see extreme swelling, blood or green discharge, or your Yorkie is inconsolable, take action. A PetMD list notes any of these post-op issues need vet care: fever, difficulty urinating, uncontrolled pain, vomiting/diarrhea, or if the incision opens.

Bathing/grooming:

No baths until the vet says it’s safe (usually after stitches are removed). The incision needs to stay dry. When you do bathe your Yorkie again (typically 10–14 days later), use a gentle shampoo. I highly recommend a Yorkie-specific formula like the 2-in-1 PH-balanced shampoo/conditioner. It’s designed for sensitive Yorkie skin, cleans without irritation, and will leave her coat soft. Keep clipping her nails short, but wait on full grooming until cleared.

Final Thoughts

Deciding to spay or neuter your Yorkie involves weighing the long-term health and behavior benefits against the short-term surgery risks. Most pet parents find that the benefits – like preventing disease, unwanted litters, and reducing mating behaviors – are worth it. In my case, neutering my Yorkie led to a happier home (no more frantic mating chases!) and peace of mind about his health. That said, it’s normal to feel nervous about the surgery. Choose a vet you trust, and follow their guidance on timing.

Remember to incorporate loving care after the procedure. Provide a soft bed from a Yorkies-Gram collection to rest on, keep your pup quiet and fed small meals, and use an E-collar and gentle shampoo as needed. With the right prep and aftercare, neutering can be a smooth experience – setting your Yorkie up for a healthier, more relaxed future.
