If you own a male Yorkshire Terrier (Yorkie), you might have questions about their reproductive anatomy—especially regarding size, development, and overall health. While it’s not often discussed, understanding what’s normal helps you monitor your pet’s well-being.

Our dog size calculator tool can estimate typical measurements, but this guide covers everything you need to know—from average Yorkie penis size to health concerns and proper care.
Understanding Male Yorkie Anatomy
What’s the Average Size of a Male Yorkie’s Penis?
A male Yorkie’s penis is proportional to their small body size (typically 3–7 lbs). When relaxed, it usually measures:
-
0.75–1.25 inches in length
-
May extend slightly during arousal due to the bulbus glandis (a normal swelling at the base)
For a more precise estimate based on your dog’s weight and age, try our Yorkie size calculator.
Testicle Development in Yorkies
-
By 6 months, both testicles should descend into the scrotum.
-
Cryptorchidism (undescended testicles) increases cancer risk—surgery may be needed.
-
Track development with our canine health tracker.
Factors Affecting Yorkie Reproductive Health
1. Genetics & Breeding Lines
-
Teacup Yorkies may have slightly smaller anatomy.
-
Reputable breeders prioritize healthy conformation.
-
Our breeding compatibility tool assesses genetic risks.
2. Age & Maturity
-
Puppies show little visible development before 6 months.
-
Full maturity reached by 12 months.
3. Neutering Status
-
Intact males have more prominent anatomy.
-
Neutered Yorkies may have reduced size over time.
-
Use our neuter impact calculator to predict changes.
Common Yorkie Reproductive Health Issues
1. Phimosis (Tight Foreskin)
-
Prevents normal retraction, leading to infection.
-
Symptoms: Redness, swelling, or difficulty urinating.
-
Treatment: Gentle cleaning or vet intervention.
2. Balanoposthitis (Infection)
-
Caused by bacteria or yeast.
-
Signs: Discharge, excessive licking.
-
Prevention: Regular hygiene checks with our health monitor.
3. Cryptorchidism (Undescended Testicles)
-
Requires surgical removal to prevent cancer.
-
Check development using our growth tracker.
4. Priapism (Prolonged Erection)
-
Emergency condition—seek immediate vet care.
-
Our symptom checker helps assess urgency.
Breeding Considerations for Yorkies
Due to their small size, breeding Yorkies requires caution:
1. Health Screening First
-
Genetic testing for patellar luxation, heart defects, etc.
-
Our breeding health evaluator identifies risks.
2. Mating Process
-
Natural breeding can be risky; artificial insemination is often safer.
-
Our breeding assistant guides safe practices.
3. Pregnancy Risks
-
Higher chance of complications due to small size.
-
Monitor with our pregnancy tracker.
