Scottish Terrier Breed Overview
The Scottish Terrier, affectionately known as the “Scottie,” is a small but sturdy breed that originated in Scotland. Originally bred for hunting vermin and foxes, Scotties are known for their distinctive wiry coat, confident personality, and dignified demeanor. Despite their small stature, they have a bold, independent spirit and a surprisingly strong prey drive.
As a small breed, Scottish Terriers grow to their adult size relatively quickly—often reaching most of their height and weight by around 8–10 months. However, careful growth tracking is important to ensure they maintain a healthy weight, as they can be prone to obesity, which may put strain on their back and joints (American Kennel Club).
Scottish Terrier Growth Chart & Weight Ranges
| Age | Average Weight (Male) | Average Weight (Female) |
|---|---|---|
| 4 weeks | 2–3 lbs (0.9–1.4 kg) | 1.8–2.8 lbs (0.8–1.3 kg) |
| 8 weeks | 4–6 lbs (1.8–2.7 kg) | 3.5–5.5 lbs (1.6–2.5 kg) |
| 3 months | 6–8 lbs (2.7–3.6 kg) | 5.5–7.5 lbs (2.5–3.4 kg) |
| 6 months | 10–13 lbs (4.5–5.9 kg) | 9–12 lbs (4.1–5.4 kg) |
| 9 months | 15–18 lbs (6.8–8.2 kg) | 13–16 lbs (5.9–7.3 kg) |
| 12 months | 18–22 lbs (8.2–10 kg) | 16–20 lbs (7.3–9.1 kg) |
Note: Males are typically 1–3 lbs heavier than females and may appear more muscular.
How Much Bigger Will My Scottish Terrier Puppy Get?
Most Scottish Terrier puppies reach 50% of their adult weight by around 4–5 months. A useful rule of thumb is to double their weight at 16 weeks for a close adult size estimate.
Note: Since Scotties are small dogs, they usually reach their full adult size between 10 and 12 months, although some may continue to fill out in muscle and coat texture for another few months.
Scottish Terrier Growth Tips
Nutrition
- Feed a balanced small-breed puppy food formulated for high metabolism and nutrient density.
- Divide meals into 3–4 portions per day until 6 months old, then reduce to 2 meals daily.
- Avoid excessive treats—Scotties can gain weight quickly if overfed.
Exercise
- Provide short, daily walks and active play sessions to keep them fit without overexertion.
- Avoid repetitive high-impact activities until bones and joints are fully mature.
Health Watch
- Common growth-related concerns include patellar luxation, intervertebral disc disease, and obesity (Scottish Terrier Club of America).
- Keep a lean body condition and schedule regular veterinary checkups to monitor development.
