Chihuahua Terrier Mix
Chihuahua + Various Terriers cross. Also called: Chi Terrier.
The Chihuahua Terrier Mix typically weighs 6-18 lbs, needs 170-450 calories per day, and lives 12-16 yrs. Size, appearance, and temperament can vary widely depending on which parent's genes are more dominant.
Size and nutrition
The Chihuahua Terrier Mix can weigh anywhere from 6-18 lbs (2.7-8.2 kg), a wide range that reflects the size difference between the Chihuahua and Various Terriers. Because mixes are unpredictable, watch your dog's actual body condition rather than targeting a specific number on the scale.
Daily calorie needs for a Chi Terrier range from 170-450 kcal depending on their adult size, activity level, and whether they are spayed/neutered. Use our calorie calculator with your dog's actual weight for a personalized estimate.

CalculateHealth risks from both parent breeds
Mixed breed dogs can inherit health conditions from either parent breed. The Chihuahua Terrier Mix may be susceptible to conditions common in both Chihuahuas and Various Terrierss. Mixed breeds often benefit from hybrid vigor, but this is not guaranteed, and responsible health screening of parent dogs remains important.
Look up the health profiles for both parent breeds for a complete picture of potential health concerns:
Exercise and activity
Small but feisty, Chi-Terriers have more energy than their size suggests. Short walks, indoor play, and training sessions satisfy their activity needs. They are nimble and enjoy agility-style obstacles scaled to their size.
Care and grooming
Grooming depends on which parent's coat dominates. Smooth coats need weekly brushing; wire or rough coats need occasional hand-stripping. Their small size makes them vulnerable to cold; a sweater is practical, not just fashionable, in winter.
What to expect from a Chi Terrier
Terrier boldness combined with Chihuahua loyalty creates a confident, sometimes bossy little dog. They bond intensely with one person and can be suspicious of strangers. Early socialization prevents the 'small dog syndrome' of excessive barking and aggression.
Frequently asked questions
Adult Chi Terriers typically weigh 6-18 lbs (2.7-8.2 kg). The wide range reflects the size difference between Chihuahuas and Various Terrierss. First-generation crosses (F1) are the most unpredictable for size. Looking at the parents' sizes gives the best estimate. Puppies that are larger at 8 weeks tend to be larger adults, but this is not guaranteed.
Daily calorie needs range from 170-450 kcal depending on your dog's actual adult size and activity level. Since mixes vary so much in size, use our calorie calculator with your dog's current weight rather than relying on breed averages. Weigh your dog monthly and adjust portions to maintain healthy body condition.
Mixed breeds often benefit from hybrid vigor, meaning their broader gene pool reduces the risk of conditions that concentrate in purebred lines. However, a Chihuahua Terrier Mix can still inherit health issues common to either the Chihuahua or the Various Terriers. Research both parent breeds' health profiles and ask the breeder about health testing of the parents. Regular veterinary checkups catch any inherited conditions early.
