The Maltese is a petite toy breed, typically weighing 4-7 pounds as adults. Their reproductive anatomy is proportionally small but completely normal for their size. Here’s what owners should know:

Average Size & Development
- Relaxed length: 0.75-1.25 inches
- Aroused length: May appear slightly longer due to bulbus glandis swelling
- Testicles: Should descend fully by 6 months of age
Note: These measurements can vary slightly based on individual genetics and body weight. For a general size reference, consult our breed-specific size guide.
Growth Timeline
Age Range | Developmental Stage |
---|---|
0-3 months | Minimal visible development |
3-6 months | Testicles descend, gradual growth |
6-12 months | Reaches full maturity |
Health Considerations
Common Issues in Maltese
- Phimosis (tight foreskin)
- May require veterinary attention if causing urination problems
- Balanoposthitis (infection)
- Symptoms include redness, discharge, or excessive licking
- Cryptorchidism (retained testicles)

Preventative Care Tips

- Natural mating is possible but requires supervision
- C-sections are common for delivery
Neutering Advice

- Benefits: Eliminates testicular cancer risk, reduces marking
- Post-op care: Monitor weight and activity levels
When to Visit the Vet
Seek professional help if you notice:
