Full-grown Chiweenie age

Chiweenie is a mixed breed of purebred Chihuahua known as Mexican hotdog and Dashchund known as German taco.

Generally, the Chihuahua Dachshund mix is full-grown at the age of 8-10 months. However, that depends on the coat. If the coat is short then your Chiweenie will reach its full age at the age of even 4-6 months. If the coat is long then it will become full-grown at the age of 6-10 months.

There is also a difference between female and male Chiweenie growth time. If you have a female Chiweenie and you don’t want to spay it early then it will stop growing earlier. If not, then it will keep on growing taller.

Size, Weight & Coat of the Full-Grown Chiweenie

Whether your mixed breed is fully grown or not depends on the size & weight of its parent breeds.  Chihuahua’s and Dachshund’s height is the same about 6-9 inches tall. However, if your Chiweenie came up as a result of the crossing between Chihuahua and Mini Dachshund then you will have a 5-6 inches small dog.

As for weight, the full-grown Chihuahuas weigh 3-7 pounds and Daschunds weigh 16-32 pounds. Thus, your Chiweenie will probably weigh about 5-12 pounds at a full-grown age. However, the dog breed weight also depends on the way you care for it. You should overfeed them, as it is crucial for their health. We will go deep into that below.

Pets will also grow in width after it reaches their full-grown age of about 8-10. It will continue to gain muscle mass and grow in the chest. However, that will not affect the weight a lot.
