Bedlington Terriers are unique dogs with a lamb-like appearance and lively personalities. To know when they reach full maturity, we need to explore their growth stages. These stages include puppyhood, adolescence, and adulthood. Each phase has specific physical and behavioral changes.
Puppyhood (0–6 Months)
Bedlington Terrier puppies grow rapidly during their first six months. At birth, they weigh about 8–12 ounces. By six months, most weigh between 10–15 pounds. Their legs lengthen, and their signature curly coat begins to develop. Puppies at this age are highly energetic and require frequent meals (3–4 times daily) to support growth.
Adolescence (6–12 Months)
Between six months and one year, Bedlingtons enter adolescence. Growth slows slightly, but muscle development becomes noticeable. Their chest widens, and their head takes on a more refined shape. This stage is critical for training, as teenage Bedlingtons may test boundaries. By 12 months, most reach 80–90% of their adult size.
Adulthood (12–18 Months)
Bedlington Terriers typically reach full physical maturity between 12 and 18 months. By this age, their skeletal structure solidifies, and their weight stabilizes. Adult males usually weigh 17–23 pounds, while females range from 15–20 pounds. Their height at the shoulder averages 15–17.5 inches.
Factors Influencing Growth Rate
Genetics
A Bedlington’s growth timeline depends heavily on its lineage. Puppies from smaller parents often mature faster than those from larger lines. Reputable breeders track growth patterns across generations and can provide estimates.
Nutrition
High-quality puppy food supports steady growth. Look for formulas with:
- 22–25% protein
- 8–12% fat
- Calcium-to-phosphorus ratio of 1.2:1
Avoid overfeeding, as excess weight can stress developing joints.
Health Conditions
Some health issues may affect growth:
- Copper Toxicosis (common in the breed) impacts nutrient absorption
- Patellar Luxation alters leg development
- Hip Dysplasia (rare but possible) affects mobility
Regular vet checks ensure early intervention if problems arise.
Physical Signs of Full Maturity
Height and Weight
Most Bedlingtons stop growing taller by 14 months. Weight gain may continue until 18 months as they fill out. Use this table as a general guide:
| Age | Male Weight | Female Weight |
|---|---|---|
| 6 months | 12–16 lbs | 10–14 lbs |
| 12 months | 18–21 lbs | 15–18 lbs |
| 18 months | 20–23 lbs | 17–20 lbs |
Coat Development
The adult coat replaces puppy fur between 9–15 months. Mature Bedlingtons have a mix of soft undercoat and wiry topcoat. Their signature “topknot” on the head becomes fully formed during this period.
Dental Development
Puppies lose baby teeth by 6 months. Adult teeth should be fully erupted and white by 18 months. Missing or discolored teeth may indicate health issues.
Behavioral Maturity
Energy Levels Stabilize
While adult Bedlingtons remain playful, their hyperactivity decreases around 2 years old. They develop better impulse control and can focus during training sessions.
Social Behavior
True social maturity emerges at 18–24 months. Adult Bedlingtons:
- Establish stable relationships with other pets
- Become less reactive to strangers
- Show consistent personality traits
Training Readiness
Though trainable at any age, Bedlingtons respond best to commands after 14 months when they can concentrate for longer periods. Complex tasks like advanced agility training should wait until full maturity.
Health Considerations for Growing Bedlingtons
Exercise Requirements
Adjust activity levels as your dog grows:
- 0–6 months: 15–20 minutes of play, 3 times daily
- 6–12 months: 30–45 minute walks, twice daily
- 12+ months: 60+ minutes of varied exercise daily
Avoid forced running or jumping until growth plates close (around 14 months).
Nutritional Adjustments
Switch from puppy to adult food between 12–14 months. Adult formulas have:
- Lower calories (300–400 kcal/cup vs. 400–500 for puppies)
- Reduced protein (18–22%)
- Added joint supplements like glucosamine
Spaying/Neutering Timing
Vets recommend waiting until at least 12 months for this breed. Early sterilization (before 6 months) may increase risks of:
- Urinary incontinence
- Bone cancer
- Obesity
Common Growth-Related Questions
Why is My Bedlington Still Small at 1 Year?
Some lines mature slower. If your dog is healthy and steadily gaining weight, this is normal. Consult your vet if:
- Weight drops suddenly
- Coat appears dull
- Energy levels decrease
When Do Bedlingtons Calm Down?
Most show noticeable calmness by age 3. However, they remain more active than average terriers. Regular mental stimulation helps manage their energy.
How to Tell if Growth Plates Are Closed?
X-rays at 14–16 months provide definitive answers. Physical signs include:
- No visible “knobbly” joints
- Consistent paw size for 3+ months
- Stable height over 60 days
Comparing Bedlingtons to Other Terriers
Growth Rate Comparison
| Breed | Full Growth Age | Adult Weight |
|---|---|---|
| Bedlington Terrier | 12–18 months | 15–23 lbs |
| Border Terrier | 10–12 months | 11–15 lbs |
| Airedale Terrier | 18–24 months | 40–65 lbs |
Bedlingtons grow slower than small terriers but faster than large ones.
Unique Growth Traits
Three features distinguish Bedlington development:
Elongated Skull: Final head shape emerges late (16–18 months)
Flexible Spine: Allows jumping ability but requires core muscle development
Single Coat Transition: Unlike double-coated breeds, their coat changes texture completely
Supporting Healthy Growth
Recommended Supplements
Omega-3 Fatty Acids: Support brain and coat health
Probiotics: Aid digestion during dietary changes
Chondroitin: Protects developing joints
Growth Monitoring Tools
Weekly Weight Logs: Use a digital pet scale
Body Condition Scoring: Check rib visibility and waist definition
Paw Measurements: Adult paw size correlates with 60% of final weight
Warning Signs of Stunted Growth
Contact your vet if you notice:
- Symmetrical bald patches
- Crusty nose or eye discharge
- Persistent loose stools
- Reluctance to jump or climb stairs
Conclusion
Bedlington Terriers reach full physical maturity between 12–18 months, but their unique characteristics continue developing until age 3. Owners should focus on consistent care rather than strict timelines. Regular vet visits, proper nutrition, and tailored exercise ensure your Bedlington grows into a healthy, happy adult. Remember—every dog matures at their own pace. Celebrate small milestones and enjoy watching your lamb-like companion blossom!
