1. What Is a Rat-Cha (Chihuahua Rat Terrier Mix)?
The Rat-Cha is a designer dog breed created by crossing a Chihuahua with a Rat Terrier. This hybrid dog combines the bold, spirited personality of the Chihuahua with the high-energy, alert, and athletic nature of the Rat Terrier.
Though not officially recognized by the AKC, Rat-Chas are recognized by the Designer Breed Registry and other hybrid dog clubs. Known for their loyalty and compact size, they’re a great fit for city dwellers and small families.

The appearance of a Chihuahua mix with Rat Terrier can vary. Some may have the Chihuahua’s apple-shaped head, while others lean more towards the sleek, athletic build of the Rat Terrier. Coat types may be short and smooth or slightly wiry, and color combinations can include black, white, tan, brown, and brindle.
3. Temperament & Behavior
The Rat-Cha is known for being:
- Energetic and playful
- Loyal and alert
- Sometimes wary of strangers (early socialization is key)

They bond closely with their owners and enjoy being involved in family activities. While affectionate, their terrier instincts can make them barky and sometimes territorial. Consistent training can mitigate this.

Training Tips:
- Use positive reinforcement (treats, praise)
- Be consistent and patient

A high-quality kibble designed for small breeds is best. Ensure:

- No fillers or artificial preservatives
- Portion control: 2 small meals per day
Be cautious with treats to prevent obesity. Chihuahua mix with Rat Terrier can have sensitive digestion, so gradual food changes are recommended.

- Bathing: Monthly or as needed
- Nail trimming: Every 3–4 weeks
