Small in stature but big in personality, the Shih Tzu is a beloved companion dog known for its “eager-to-please” nature [3]. However, many owners of “Toy” or “Imperial” sized Shih Tzus—those often bred to be smaller than the standard 9–16 pounds—face a unique biological hurdle: the remarkably small bladder.
Because of their size, these dogs process fluids quickly and have less physical capacity to “hold it” compared to larger breeds. While experts at Dogster note that these dogs are intelligent and capable of learning, their physical limitations require a specialized training approach.

The Small Bladder Reality: Timing and Biology
For a Toy Shih Tzu, the “one hour per month of age” rule is the absolute maximum, not a suggestion. A three-month-old puppy may technically be able to hold its bladder for three hours, but high activity or excitement can reduce that window to 30 minutes [4].
Critical Potty Windows:
Post-Nap: Take them out immediately upon waking.
Post-Play: High activity stimulates the bowels and bladder [2].
Post-Consumption: Puppies often need to relieve themselves 15–30 minutes after eating or drinking.
The Sniff-and-Circle: This is the universal “pre-potty” behavior. If you see your Shih Tzu sniffing intently or circling in one spot, pick them up immediately and head to the designated area [5].
While the general rule is one hour per month of age, toy breeds often need breaks every 30 to 60 minutes during periods of high activity or excitement. It is critical to take them out immediately after they nap, play, or consume food and water.
Keep a close eye out for the “sniff-and-circle” behavior. If your dog begins sniffing the floor intently or circling in one spot, they are preparing to relieve themselves and should be taken to their designated potty area right away.
Choosing Your Method: Indoor vs. Outdoor
For urban dwellers or owners of very small Toy Shih Tzus, traditional outdoor-only training can be difficult due to the frequency of breaks needed.
1. The Outdoor Routine
If you choose outdoor training, consistency is your best tool. Experts at wikiHow recommend using a consistent “potty word” (like “business” or “hurry up”) to create an association between the command and the action.
The Special Spot: Take them to the exact same patch of grass 每一次. The scent of previous “successes” triggers their instinct to go again [4].
The Wait: Stay outside for at least 10 minutes. Small dogs often get distracted by leaves or wind and “forget” why they are there.
2. Indoor Solutions (The “Apartment Strategy”)
Because Toy Shih Tzus struggle with long durations, many owners utilize indoor options.
Pee Pads/Litter Boxes: These are effective for tiny breeds but can make transitioning to outdoors harder later.
Artificial Grass/Porch Potties: Products like the Porch Potty allow the dog to feel grass beneath their paws, which makes the eventual transition to the yard much smoother.
Small dogs are easily distracted by environmental factors like wind or moving leaves. To combat this, stay in one designated spot for at least 10 minutes and use a consistent “potty word” to help them focus on the task.
Yes, indoor solutions like artificial grass or porch potties are excellent for small breeds that struggle with long durations. These systems are often better than pee pads because the grass texture makes it easier for the dog to eventually transition to outdoor training.
The Crate and Boundary Method
Dogs have a natural instinct to keep their “den” clean. Using a crate is the most effective way to teach bladder control, provided it is sized correctly.
Sizing: The crate should be just large enough for the dog to stand, turn around, and lie down [1]. If it is too large, a Toy Shih Tzu will potty in one corner and sleep in the other.
Supervision: When the dog is not in the crate, they should be in a “confinement zone” (like a playpen with easy-to-clean flooring) or attached to you via a “tether” (a 6-foot leash). This prevents them from wandering off to a hidden corner to have an accident.
The crate should only be large enough for the dog to stand, turn around, and lie down. If the crate is too big, the puppy may utilize one corner as a bathroom and the other as a bed, which defeats the purpose of the training.
When not crated, keep your Shih Tzu in a confined playpen with easy-to-clean floors or use the “tether method” by keeping them on a 6-foot leash attached to you. This ensures they cannot wander off to a hidden corner of the house to potty.
Overcoming the “Stubborn” Myth
Shih Tzus are often labeled “stubborn,” but community discussions on Reddit’s r/Shihtzu suggest that what owners perceive as stubbornness is often a lack of clear communication or a reaction to cold/wet weather.
Positive Reinforcement: Shih Tzus respond poorly to scolding. If you catch them in the act, a firm “No” followed by an immediate trip outside is enough. Praise and high-value treats (like small pieces of boiled chicken) must be delivered within three seconds of them finishing their business outside [2].
Weather Sensitivity: Small dogs lose body heat quickly. If it’s raining or snowing, a Toy Shih Tzu may refuse to go outside. Using a sweater or providing a covered outdoor area can mitigate this refusal.
Toy Shih Tzus are highly sensitive to temperature and lose body heat quickly. If your dog refuses to go in bad weather, try using a dog sweater or providing a covered outdoor area to make them feel more comfortable.
Use high-value treats like small pieces of boiled chicken and offer praise within three seconds of them finishing their business. Positive reinforcement is much more effective than scolding, as Shih Tzus respond poorly to harsh corrections.
Summary of Key Takeaways
Action Plan
- Establish a 2-Hour Schedule: Regardless of age, take your Toy Shih Tzu to their potty spot every two hours during the day.
- Size Your Crate: Ensure the crate is small enough specifically for a “Toy” size to utilize their natural denning instinct.
- Use High-Value Rewards: Keep a “potty only” treat jar by the door. Reward immediately after they finish, not when they get back inside.
- Neutralize Accidents: Use an enzymatic cleaner (like Nature’s Miracle) to remove scent markers. Standard soap does not break down the proteins that tell a dog “this is a bathroom” [1].
- Monitor Water Intake: Provide plenty of water, but consider picking up the bowl 2 hours before bedtime to reduce middle-of-the-night accidents.
While the Toy Shih Tzu’s small bladder presents a challenge, their desire for companionship and intelligence makes them highly trainable. With a strict schedule and an emphasis on positive reinforcement, most Shih Tzus can be fully house-trained within 4 to 8 weeks [4].
| Training Category | Action Item |
|---|---|
| Schedule | Mandatory potty breaks every 2 hours and after all activities. |
| Crate Size | Snug fit: only enough room to stand, turn, and lie down. |
| Reward System | High-value treats delivered within 3 seconds of success. |
| Cleanup | Use enzymatic cleaners to fully dissolve scent proteins. |
| Night Routine | Pick up water bowls 2 hours before the final bedtime trip. |
With a consistent schedule and positive reinforcement, most Shih Tzus can be fully house-trained within 4 to 8 weeks. Success depends heavily on maintaining a strict two-hour schedule and using effective rewards.
Always use an enzymatic cleaner rather than standard soap or ammonia-based products. Enzymatic cleaners break down the specific proteins in pet waste that act as scent markers, which discourages the dog from returning to that same spot.
