Chihuahuas are small in size but big in personality, and that combination trips up even well-meaning owners. Many training struggles with this breed don’t come from a lack of effort — they come from a handful of common mistakes that quietly work against you. Below are 12 of the biggest ones, along with the best way to handle each situation instead.
1. Treating Them Like “Too Small to Train”
It’s tempting to let a four-pound dog get away with behavior you’d never accept from a Labrador — jumping, nipping, or barking at guests. This mindset is one of the most common reasons Chihuahuas end up poorly behaved. The best way to avoid this is to apply the same training standards you would to any dog, regardless of size. Consistency early on prevents “small dog syndrome” from taking root, and it teaches your Chihuahua that the same rules apply to them as to a much bigger dog.
2. Skipping Socialization Because They’re “Just a Lap Dog”
Many owners assume a Chihuahua’s small size means it doesn’t need much exposure to the outside world. Left unsocialized, Chihuahuas often become fearful or reactive toward strangers, other dogs, and new environments. The best way to prevent this is to start socialization early and keep it going — short, positive exposures to new people, pets, sounds, and places, ideally beginning as early as 8–16 weeks old and continuing throughout adulthood.
3. Using Harsh Corrections or a Raised Voice
Because Chihuahuas are so small, some owners assume a stern tone or physical correction is harmless. In reality, this breed is highly sensitive, and harsh handling tends to create fear and mistrust rather than obedience. The best way to correct unwanted behavior is with calm redirection and positive reinforcement — reward the behavior you want to see rather than punishing the behavior you don’t, and your Chihuahua will learn faster and trust you more.
4. Giving In to Begging or Demand Barking
A tiny dog staring up with big eyes is hard to resist, so many owners cave to whining, pawing, or barking for attention or food. This accidentally teaches the dog that persistence gets results, which reinforces the very behavior you’re trying to stop. The best way to handle this is to only reward calm, quiet behavior — wait for a pause in the barking or begging before giving attention, treats, or affection, so your dog learns that calmness, not demands, gets the reward.
5. Inconsistent Rules Between Family Members
If one person allows the dog on the couch and another doesn’t, or one person tolerates jumping while another scolds it, the dog receives mixed signals and struggles to learn any rule at all. The best way to fix this is to set household rules as a family before training begins, and make sure everyone — including guests, when possible — enforces them the same way every time.
6. Training Sessions That Are Too Long
Chihuahuas have short attention spans, and dragging out a training session past their limit often leads to frustration, disengagement, or the appearance of “stubbornness.” The best way to train effectively is to keep sessions short — around 5 to 10 minutes, several times a day — and always end on a successful note so your dog associates training with a win rather than exhaustion.
7. Skipping Crate Training
Some owners assume crate training is unnecessary for such a small dog, or view it as unkind. Without it, though, Chihuahuas can struggle with separation anxiety, housetraining, and feeling secure when left alone. The best way to introduce a crate is gradually and positively — make it a comfortable, treat-associated space rather than a punishment, so your dog sees it as a safe den rather than confinement.
8. Not Housetraining With a Consistent Schedule
Because of their small bladders, Chihuahuas are notorious for being difficult to housetrain, and inconsistent bathroom schedules make the problem worse. The best way to housetrain successfully is to take your dog out at the same times every day — after waking, after eating, and after play — and reward them immediately after they go in the right spot, so the connection between location and reward stays crystal clear.
9. Letting Fear-Based Aggression Go Unaddressed
Chihuahuas can develop a reputation for snapping or growling, but this is usually rooted in fear rather than dominance. Ignoring early warning signs — stiffening, growling, or avoidance — often allows the behavior to escalate. The best way to address this is to identify and remove the dog from triggering situations early, then work on gradual, positive exposure at a distance the dog can handle without fear, building confidence step by step rather than forcing confrontation.
10. Over-Relying on Carrying Them Everywhere
Carrying a Chihuahua constantly feels natural given their size, but it can prevent them from learning to walk confidently on a leash training, explore independently, or cope with the ground-level world. The best way to build independence is to let your dog walk on their own for as much of the day as safely possible, reserving carrying for genuinely necessary situations like crowded or hazardous areas.
11. Using Punishment for Fear-Based Behaviors Like Potty Accidents
Scolding a Chihuahua for an accident or a fear response often backfires, since punishment for something the dog didn’t understand tends to create anxiety rather than correction. The best way to handle these moments is to redirect calmly in the moment and clean up without drama, then reinforce the correct behavior next time with a reward — never punish after the fact, since dogs don’t connect delayed punishment with the original action. Give dog Potty training, barking training, clicker training when dog is under one months.
12. Expecting Obedience Without Building Trust First
Some owners jump straight into commands and drills without first building a bond, which leaves a naturally independent breed like the Chihuahua unmotivated to listen. The best way to set training up for success is to invest time in relationship-building first — play, calm affection, and positive daily interactions — so your dog is working with you because they trust you, not just because you’re asking.
Final Thoughts
Most Chihuahua training struggles trace back to one of these twelve patterns, and the fix is almost always the same: consistency, patience, and positive reinforcement over force or leniency. Avoid these common mistakes, and you’ll find that this breed’s famous stubbornness gives way to a surprisingly quick, eager learner — one who’s simply been waiting for training that actually makes sense to them.
