The Chihuahua is famously the smallest dog breed in the world, but don’t let their size fool you. These tiny dogs have a big personality and, as many owners learn, can sometimes be one of the most challenging breeds to train. This often comes from treating them more like babies than dogs, which can unintentionally create behaviour problems.
Chihuahuas suit small homes and apartments perfectly, making them popular among lovers of small dogs. Their celebrity status as "handbag dogs" sometimes encourages owners to carry them everywhere, which can neglect their natural needs for activity and socialisation.
Sadly, they are also among the breeds most often surrendered to shelters, usually due to behavioural issues that arise when left untrained or improperly managed. However, with the right approach starting from puppyhood — or when adopting an older dog — these problems can be overcome.
The core issue behind many behavioural challenges lies in failing to see your Chihuahua as a dog with canine needs. It’s perfectly fine to love your dog like a family member, but discipline and clear rules are vital. Physical punishment is never helpful and can worsen behaviour, so instead focus on firm, positive reinforcement training.
If your Chihuahua is snapping, nipping, or behaving as if they are the alpha of the household — demanding treats, the best sofa spot, or sleeping in your bed — this is a sign your leadership needs reinforcing. You must calmly but firmly reassert your position as the pack leader to help your dog understand boundaries.
Chihuahuas’ tiny teeth can nip hard and cause real injury, so bite inhibition is important. When your dog snaps or nips inappropriately, respond consistently. Gently discourage biting during play by saying “ouch” and withdrawing attention when biting occurs.
Regular training to respond to commands like “sit,” “stay,” and “come” improves control and reduces unwanted behaviour. Always use clear, consistent commands and reward good manners with treats only during training sessions.
Treats, sofa time, and other benefits are privileges your Chihuahua needs to earn through good behaviour, not rights. If your dog protests or snaps when denied privileges, immediately remove the benefit and place them in a short time-out to calm down.
Every dog benefits from knowing basic obedience commands. Prioritise teaching your Chihuahua to sit, stay, come when called, and accept walking on the lead rather than being carried everywhere. It may take patience, especially with older dogs, but persistence is key to success.
Some behavioural issues stem from anxiety rather than disobedience. Pay attention to whether your Chihuahua exhibits signs of stress or fear. For example, excessive barking, whining, or clinginess may signal separation anxiety or other emotional distress. In these cases, adapting your training approach and providing a secure routine helps, and consulting a behaviourist may be beneficial.
Training a Chihuahua requires consistent application of rules and commands by everyone in the household. Mixed messages confuse your dog and delay progress. Firm but loving leadership coupled with patience fosters well-behaved, happy pets.
By seeing your Chihuahua as a spirited dog needing structure, applying positive reinforcement training, and setting clear, consistent boundaries, you can transform your tiny terror into a delightful companion. If issues persist, seeking guidance from a professional dog trainer or veterinary behaviourist can make a big difference.
