5 Honest Reasons Why Shih Tzu Are the Worst Dog to Some Owners

Why Shih Tzu are the worst dog to some dog owners may sound harsh at first, but for a breed as beloved as the Shih Tzu, it’s important to look at both the adorable and the occasionally frustrating sides. These small, fluffy companions are known for their affectionate nature, playful charm, and royal history. For many, they’re the perfect lapdog.

However, not every dog breed is right for every person. While countless families adore their Shih Tzus, others discover unexpected challenges that make this breed less ideal for their lifestyle. From grooming demands to training hurdles, there are some honest reasons why Shih Tzus might not be the best choice for certain owners.

High Maintenance Grooming Needs

One of the biggest reasons why Shih Tzu are the worst dog to some dog owners is their demanding grooming routine. With their long, flowing double coats, Shih Tzus are undeniably beautiful—but that beauty comes with a cost. These coats aren’t just for show; they require daily brushing to prevent tangles and painful matting. Without regular attention, the hair around their ears, tail, and belly can become knotted, leading to discomfort or even skin infections.

Professional grooming isn’t optional for this breed—it’s a necessity. Many Shih Tzu owners find themselves scheduling grooming appointments every 3 to 6 weeks just to keep their dogs clean and comfortable. That can add up quickly, both in time and money. On top of that, the daily at-home maintenance involves cleaning their face, wiping tear stains, and trimming hair around their eyes and paws.

If neglected, their coat can trap dirt and moisture, which leads to skin issues such as hot spots, yeast infections, and a generally foul odor. This high-maintenance upkeep often catches new owners off guard—especially those who assume a small dog means less effort.

According to the American Kennel Club (AKC), “a Shih Tzu’s long, luxurious coat needs brushing every day to keep it free of tangles.” And while some owners opt to keep their Shih Tzus in a shorter “puppy cut,” the maintenance still remains higher than average compared to other small breeds.

Stubborn and Difficult to Train

Another reason why Shih Tzu are the worst dog for some owners is their reputation for being stubborn and tough to train. While they’re undeniably charming and affectionate, Shih Tzus were originally bred as companion dogs—not for working or obedience. This history plays a significant role in their temperament. They’re known for their independent streak, which often translates to a “What’s in it for me?” attitude during training sessions.

Many new Shih Tzu owners are surprised to discover that simple commands like “sit” or “come” can take weeks—if not longer—for these little dogs to grasp consistently. It’s not that they aren’t intelligent; in fact, Shih Tzus are quite clever. But they’re also strong-willed and can be easily distracted or simply uninterested in pleasing their human unless there’s a reward involved.

Housebreaking is another area where owners commonly struggle. They can take longer than average to become fully house-trained, and they may regress without a strict, consistent routine. Their small bladders require frequent potty breaks, and without patience and persistence, accidents indoors can become a recurring issue.

According to Vetstreet, Shih Tzus are often ranked lower on the list of easiest breeds to train, not due to a lack of intelligence but because of their willful nature. Experts emphasize the importance of positive reinforcement—using treats, praise, and patience—while steering clear of punishment-based methods, which may cause them to shut down or resist further.

Training a Shih Tzu often demands more effort than other small breeds; that’s why many first-time dog owners feel frustrated and consider Shih Tzu as the worst dog.

Prone to Specific Health Issues

Health issues are another significant reason that makes Shih Tzu the worst dog for many owners—especially those who aren’t ready for the financial and emotional toll of frequent vet visits. Though they’re generally loving companions, Shih Tzus come with a set of breed-specific medical concerns that often require long-term care and attention.

One of the most concerning issues is brachycephalic airway syndrome, a condition caused by their flat, short noses and compressed airways. This can lead to breathing difficulties, snorting, loud snoring, and intolerance to heat or intense activity. In some cases, corrective surgery is needed to help the dog breathe more comfortably, which can be costly and stressful for both the pet and the owner.

Shih Tzus are also known for their sensitive eyes. Their large, protruding eyes are prone to scratches, infections, dry eye, and even corneal ulcers. Eye drops and vet checkups can become routine, and in severe cases, surgery or ongoing medication may be necessary. This vulnerability adds another layer of responsibility that many new owners don’t anticipate.

In addition, dental health is a persistent challenge in the breed. Due to their small jaws and crowded teeth, Shih Tzus are more likely to suffer from gum disease, plaque buildup, and tooth loss. Without proper dental hygiene, they may need professional cleanings or extractions—procedures that can be expensive and require anesthesia.

According to sources like the American Kennel Club (AKC) and PetMD, these health issues are relatively common among Shih Tzus and often begin showing up early in life. Preventive care helps, but the commitment to ongoing vet visits and medical expenses is something every potential Shih Tzu owner must be prepared for.

While no dog is entirely free from health concerns, the frequency and nature of these issues are among the key reasons why Shih Tzu are the worst dog for those who want a low-maintenance or budget-friendly pet experience.

Physically Limited: Not Ideal for Active Lifestyles or Harsh Weather

Shih Tzus were bred as lap dogs, not adventure companions. If you lead an active lifestyle filled with hiking, jogging, or frequent outdoor trips, this breed may not keep up. Their small legs, short snouts (brachycephalic features), and moderate stamina make extended activity difficult.

Additionally, their flat faces put them at high risk in extreme temperatures. Shih Tzus can overheat quickly in the summer and are vulnerable to chills in winter. According to the American Kennel Club, owners should avoid exposing them to harsh weather and stick to short walks during milder parts of the day.

If you’re seeking a low-maintenance, weather-tolerant, or athletic dog, the Shih Tzu’s physical limitations could be frustrating.

Emotionally Demanding: Prone to Separation Anxiety and Easily Overwhelmed

Shih Tzus form deep bonds with their owners, but this attachment comes at a cost. They’re prone to separation anxiety, often displaying distress when left alone for long periods. Chewing, barking, or pacing are common signs, and these behaviors can disrupt households or irritate neighbors.

This sensitivity extends to how they interact with their environment. While some Shih Tzus tolerate children well, many get stressed by loud noises, rough handling, or chaotic play. Unlike sturdier breeds, they’re easily overwhelmed and may react with fear or defensive nips when pushed beyond their comfort zone.

If your home is often busy or you’re away for extended hours, this breed’s emotional needs may become a serious concern.

Why Some People Absolutely Love Shih Tzus

While this article focuses on the challenges of owning a Shih Tzu, it’s only fair to recognize why many dog lovers adore this charming breed. Despite their quirks, Shih Tzus offer several wonderful traits that make them beloved companions for the right owners.

1. Loyal and Affectionate Companions

Shih Tzus are incredibly loving lap dogs. They thrive on human companionship and often form deep emotional bonds with their owners. If you’re someone who enjoys cuddles on the couch, a Shih Tzu will happily be your shadow.

2. Ideal for Apartment Living

Due to their small size and low exercise requirements, Shih Tzus are perfect for city dwellers or apartment residents. They don’t need a backyard to be happy, as long as they get regular indoor playtime and short walks.

3. Minimal Shedding

While Shih Tzus require grooming, they shed very little, making them a potential option for people with mild dog allergies. Their hair is more like human hair than fur, which helps reduce allergens in the home.

4. Great for Seniors or Homebodies

Because they enjoy a relaxed, slow-paced lifestyle, Shih Tzus are excellent pets for seniors, retirees, or people who spend a lot of time at home. They are content just being near their humans and don’t demand constant activity.

5. Playful and Cheerful Temperament

Shih Tzus may be small, but they have a big personality. They’re often described as friendly, curious, and playful, bringing a dose of daily joy to their households with their goofy antics and sweet expressions.

Final Thoughts: Is the Shih Tzu Truly the Worst Dog?

Of course, “worst” is a subjective term. For the right person—someone who is home often, has the time and resources for grooming and vet care, and enjoys the idea of a loyal lapdog—the Shih Tzu can be an incredibly rewarding companion.

But honesty matters when choosing a breed. Shih Tzus aren’t “bad dogs,” but they do have specific needs and quirks that clash with certain lifestyles. Understanding these challenges ahead of time helps ensure that both pet and owner end up in a happy, healthy, lifelong relationship.
