The Owner's Influence on the Chihuahua
1. If the owner asks the Chihuahua to do something it is unable to accomplish, the dog will experience frustration in training. If the dog makes a mistake unintentionally and the owner responds with hitting or scolding, training becomes even more difficult.
2. If the commands used in training are mixed together with ordinary daily conversation, the Chihuahua will have a harder time forming a strong conditioned response to the command. Extra and unnecessary speech becomes a new stimulus and distracts the dog, which interferes with its ability to follow the training cue.
3. "Over-limit" training means training the dog for too long and repeating the same movement or subject again and again until its nervous system becomes overly tired. This delays learning and in some cases causes the dog to give up entirely. Training therefore needs a balance between work and rest so the Chihuahua does not become overly fatigued.

The Influence of Climate and Environment
1. Climate: Wind direction, wind speed, and wind force can all affect training results, especially the Chihuahua's scent recognition and smell discrimination ability. Wind can also help or hinder the transmission of spoken commands.
2. Environment: The training ground should not be too noisy. Heavy pedestrian or vehicle traffic creates many different stimuli for the Chihuahua. Environmental interference directly affects training quality.

The Influence of Feeding and Management
Feeding management is closely linked to training. Only with correct and scientific feeding can a Chihuahua participate normally in training. Dirty bowls, stale food, spoiled food, irregular feeding times, irregular feeding amounts, and lack of proper nutritional standards can all directly or indirectly interfere with training and handling.
So there are many factors that affect the training effect of a Chihuahua. Sometimes poor results do not mean the dog is not smart enough; the environment at that moment may simply be unfavorable. Owners should understand these factors and avoid them as much as possible.
