Professor Stanley Coren, the famous psychology/neuropsychological professor and, dog lover/trainer measured and ranked the intelligence of about 130 different dog breeds.
According to Prof. Stanley Coren, the total intelligence that a dog demonstrates is the addition of three types of intelligence. These intelligence types are:Prof. Coren showed that the Working/Obedience Intelligence of different dog breeds can be measured reliably. Thus, he was able to rank different dog breeds based on their Working/Obedience Intelligence.
This is important because according to Prof. Coren, 51 percent of a dog`s intelligence comes from its genes while 49 percent of a dog`s intelligence comes from the dog`s environmental circumstances.
To rank the intelligence of dog breeds, Prof. Coren employed the help of 208 dog obedience judges in North America to fill out a detailed survey on dog obedience. This number represented more than half of all of these judges in North America at the time. He also employed 63 veterinarians and 14 guard dog experts to collect data on the personality of different dog breeds.Prof. Coren found that the Chihuahua has an obedience intelligence rank of 67 out of 130 dog breeds. The Chihuahua belongs to the `Fair Working/Obedience Intelligence Dogs` category. This means that Chihuahuas tend to learn new commands after 40 to 80 repetitions!.

The Sealyham Terrier is more intelligent than the Chihuahua.
However, Prof. Coren noted that a dog should not be judged based on its intelligence alone, that other factors such as sociability, adorability, and compatibility with the owner are other very important factors that new dog owners need to consider when deciding on a new dog.
