Facts & Origin
Chihuahua and American Rat Terrier in one
The Rat-Cha is a hybrid breed that was created by crossing a Rat Terrier with a Chihuahua. The aim of this cross was to combine the courageous, alert nature of the Chihuahua with the active, intelligent nature of the Rat Terrier. This cross became increasingly popular, especially in the USA, where small, smart dogs with big personalities are in great demand.
The Rat-Cha was to be a companion dog suitable for everyday use - compact, alert, easy to keep and yet full of energy and character. In practice, this resulted in a dog that is very people-oriented, but also has a certain independence.
Name synonyms for the Rat-Cha
The name Rat-Cha is the most common short form and is made up of the names of the two breeds. Sometimes the crossbreed is also referred to as Chihuahua Rat Terrier Mix or RatChi, although spelling and usage can vary from region to region. All names refer to the same type of crossbreed.
Criticism of the Rat-Cha
As with many designer dogs, the Rat-Cha is also criticized for the fact that the lack of a uniform standard makes it difficult to predict how the dogs will develop in terms of appearance or temperament. In addition, the Rat-Cha combines two breeds that are known for their willfulness and sensitivity - this can lead to a dog that is very attentive, but also easily irritable or territorial.
If he is not lovingly socialized early on, he tends to be suspicious or loud towards strangers. In untrained hands, his self-confidence can quickly turn into inappropriate behavior, such as constant barking or dominant behavior. This does not make it a suitable choice for every household, although it is often underestimated due to its size.
Suitability of the Rat-Cha
The Rat-Cha is particularly suitable for people who enjoy working with their dog, are observant and willing to set clear rules. Despite his small size, he is very active, alert and needs to be kept busy - both physically and mentally. He is not a typical lap dog, but rather a small dog with "big dog behavior".
In the right environment, with loving guidance, patience and clear communication, the Rat-Cha becomes an alert, loyal companion who seeks close contact with his caregivers and takes his family very seriously.

Attitude, character and temperament of the breed
Possible character traits of the Rat-Cha
The Rat-Cha is a bright, courageous and very loyal little dog. It observes its surroundings closely, often reacts quickly and shows a strong need for closeness to its caregivers. Many Rat-Chas are lively and playful, but at the same time alert and protective - they can become little "guards" who defend their home vociferously if they do not learn early on to distinguish between harmless and relevant stimuli.
When it comes to training, the Rat-Cha needs a mixture of patience, consistency and clear communication. Despite his small size, he is very self-confident and likes to test out what he is allowed to do. With good leadership, he will become an affectionate, eager to learn and entertaining companion who enjoys being part of everyday family life.

Health and breeding information
Possible diseases of the Rat-Cha
Like many small mongrels, the Rat-Cha carries certain health risks that can originate from its parents. Dental problems are frequently observed, as small dogs often have a narrow jaw. Patellar luxation - i.e. the kneecap jumping out - is also possible.
Eye problems, allergic reactions or a sensitive gastrointestinal tract cannot be ruled out either. Depending on how strong the Chihuahua is, the Rat-Cha may also be more susceptible to the cold and may need protection on walks in the cold season. Regular monitoring, a species-appropriate diet and exercise can generally help to improve their quality of life.
This is what a Rat-Cha can look like
The appearance of the Rat-Cha is varied and strongly depends on which parent is more dominant. It is usually a small, petite to muscularly built dog that reaches a shoulder height of around 20 to 30 cm and weighs between 3 and 6 kilograms.
Its coat is usually short, smooth and easy to care for, but can also be slightly coarse or somewhat longer - depending on the type of Rat Terrier. All typical color variations are conceivable: from solid to pied to tricolor patterns.
The ears can be carried either erect, semi-erect or drooping, the expression is usually lively and alert. Overall, the Rat-Cha appears very present, often somewhat serious or concentrated - a dog that attracts considerably more attention than its body size would suggest.
Known Diseases
