Biewer Terrier Breed Profile

Breed Overview

The Biewer Terrier (pronounced “beaver”) is a charming, elegant toy breed that originated in Germany during the 1980s. It descends from the Yorkshire Terrier but carries a distinct tri-color coat and a whimsical, playful demeanor. Developed by the Biewer family through selective breeding, the Biewer Terrier was officially recognized by the American Kennel Club (AKC) in 2021.

Known for their affectionate and intelligent nature, Biewers make excellent companions for families, singles, and seniors alike. They thrive on human interaction and are often described as cheerful, curious, and spirited. Their small size and moderate activity needs make them well-suited for apartment living.

Size Category: Small

The Biewer Terrier is a small breed, typically weighing between 4 to 8 pounds at full maturity and standing about 7 to 11 inches tall at the shoulder. Because of their petite frame, growth tracking is essential to ensure healthy development and avoid under- or overfeeding. Small breeds tend to mature faster than larger breeds, making it important to monitor weight and milestones early.

Biewer Terrier Growth Chart & Weight Ranges

Here’s a general guideline of what to expect as your Biewer Terrier puppy grows. Keep in mind that individual growth may vary depending on genetics, nutrition, and activity levels.

Age	Average Weight (lbs)
4 weeks	1.0 – 1.5
8 weeks	1.5 – 2.5
3 months	2.0 – 3.5
4 months	2.5 – 4.0
6 months	3.5 – 6.0
9 months	4.0 – 7.0
1 year	4.5 – 8.0

Gender Differences:
Males may weigh slightly more than females—typically 0.5 to 1.5 pounds heavier at full maturity. However, the difference is subtle and not as pronounced as in larger breeds.

How Much Bigger Will My Biewer Terrier Puppy Get?

Most Biewer Terrier puppies experience their fastest growth between 2 to 6 months of age. By 16 weeks (4 months), they typically reach about 50% to 60% of their adult weight.

Rule of Thumb

To estimate adult weight, double your Biewer puppy’s weight at 12 to 16 weeks. For example, if your puppy weighs 2.5 lbs at 12 weeks, their estimated adult weight will be around 5 lbs.

When Do Biewers Stop Growing?

Most Biewer Terriers reach full adult size between 9 to 12 months, though minor weight or muscle changes may occur until 14 months.

Note: Unlike giant breeds, toy breeds like the Biewer Terrier mature much faster and usually complete most of their physical growth in the first year.

Biewer Terrier Growth Tips

Nutrition

• Puppy Feeding Schedule: 3–4 small meals a day until 6 months, then transition to 2 meals per day.
• Food Type: Choose high-quality kibble or wet food formulated for toy or small breeds. Look for labels from trusted sources like AAFCO.
• Watch for Hypoglycemia: Because of their small size, Biewer puppies are prone to low blood sugar. Ensure frequent meals and monitor for signs like lethargy or shaking.

Exercise

• Daily Play: 20–30 minutes of gentle play and short walks are sufficient for a Biewer Terrier puppy.
• Avoid Overexertion: Their tiny joints are still developing—no jumping off furniture or intense agility training before 12 months.

Health Watch

While generally a healthy breed, growth-related issues can include:

• Luxating Patella: Common in toy breeds, this knee condition can develop if weight or activity is not properly managed.
• Dental Development: Small breeds often retain baby teeth—regular vet checks can catch this early.
• Tracheal Collapse: Monitor for breathing issues, especially if using a collar instead of a harness.

Routine vet visits during the first year will help ensure your Biewer Terrier is growing at a healthy rate and staying on track.
