There are different categories of Chihuahua service dogs, these are based on the main focus of what the dog has been trained to do:
They will act as the eyes of their handler, guiding them around obstacles and leading them so that they can walk safely in just about any situation…Through traffic, busy sidewalks and more.
They will act as the ears of their handler; working with deaf people. They are able to alert someone of just about any noise; depending on their training. This can include the doorbell, knocking, the ring of a telephone…even the whistle of a tea kettle.
Mobility assist –
These dogs often pick up things that are dropped, open and close doors and even help their handlers get dressed. While the Chihuahua is not often the optimum size for this type of job, they can do quite a bit such as gathering clothes for their owner to put on.
This is most often reserved for large dogs. It is their job to serve as a heavy, sturdy weight for their owner to lean on and use for support when walking.
Seizure Alert –
As talked about above, Chihuahua service dogs are trained to immediately notice the symptoms of a person entering a seizure…They then push a button on the phone that alerts 911 and a prearranged agreement will let the emergency services know that barking equals asking for help for their owner.
Those dogs in this group are close companions to those with certain mental disabilities. The most important aspect is that they are trained to remain at the owner’s side at all times. They may help a person to go outside if they have agoraphobia. They are also trained to help keep a person focused on daily, important tasks. Some even urge a handler to bath or to eat at regular times.
Chihuahua service dogs in this group are specifically trained to aid those with autism. They can urge a person to stop repeating a repetitive movement which can be distracting to the handler and also assist with other duties.
