FAQs about a Westie Puppy’s Growth and Development

1. How big will my Westie puppy grow to be?


West Highland White Terriers, commonly known as Westies, are a small-sized breed. Adult Westies typically weigh between 15-20 pounds (7-9 kg) and stand around 10-11 inches tall at the shoulder. The exact size can vary based on genetics and overall health.

2. When will my Westie puppy stop growing?


Most Westies will complete the majority of their growth by their first birthday. However, they might fill out a little more, becoming muscular and mature, until they’re about 18 months old.

3. Is it normal for Westie puppies to have growth spurts?


Yes, like many puppies, Westies can experience growth spurts. You may notice periods when they seem to grow overnight, followed by periods of slower growth.

4. What should I feed my Westie puppy to ensure proper growth?


Choose a high-quality puppy food that’s formulated for small-breed puppies. These foods provide the necessary nutrients in the right proportions for optimal growth and development.

5. How much should my Westie puppy eat each day?


The exact amount varies depending on the brand of food and your puppy’s age, size, and activity level. Always refer to the feeding guidelines on the food package and consult with your veterinarian.

6. When should I switch from puppy food to adult food?


For Westies, it’s generally recommended to transition from puppy food to adult food around 9-12 months of age. Your vet can provide guidance tailored to your puppy’s specific needs.

7. My puppy’s legs seem disproportionately long. Will he grow into them?


It’s common for puppies, including Westies, to have a somewhat “awkward” appearance during growth stages. In most cases, they will grow into their legs and achieve a more proportionate look as they mature.

8. Can I determine how big my Westie will get based on his paws?


While some people believe large paws indicate a puppy will grow to be large, it’s not a foolproof method, especially for small breeds like Westies. Genetics and overall health are better indicators.

9. Why is my Westie puppy’s coat changing colors?


It’s common for Westies to experience coat color changes as they grow. Puppies might start off with a darker coat, which gradually lightens to the characteristic white as they mature.

10. Should I be concerned about my Westie’s soft spot on his skull?


Like human babies, some puppies have a soft spot, or fontanel, on their skull that slowly closes as they grow. While it’s typically not a concern, if it remains large or doesn’t close, consult your vet.

11. Can over-exercising impact my Westie’s growth?


Yes, excessive or intense exercise in puppies can harm their developing joints and bones. Ensure playtime is balanced with rest and avoid long or strenuous activities.

12. How do I know if my Westie is overweight or underweight?


You should be able to feel your puppy’s ribs without pressing hard, and they should have a visible waist. If unsure, consult your vet for a proper weight assessment.

13. Are there growth charts for Westie puppies?


While there are general growth charts for dogs, individual growth can vary. It’s best to consult your veterinarian to ensure your Westie is growing as expected.

14. How often should my growing Westie see a vet?


Puppies should visit the vet several times in their first year for vaccinations, deworming, and general health checks. After the first year, annual check-ups are typical.

15. When will my Westie puppy’s adult teeth come in?


Westies usually start losing their baby teeth and getting their adult teeth around 3-6 months of age. The process should be complete by 7-8 months.

16. Is it normal for my puppy to have a big appetite during growth phases?


Yes, growing Westies may have increased appetites. Ensure you’re feeding them high-quality food and monitor their weight to prevent overfeeding.

17. When will my Westie’s ears stand up?


Most Westie puppies will have their ears stand up naturally between 8-12 weeks. However, some might take a bit longer. If they haven’t stood up by 6 months, consult your vet.

18. Can neutering or spaying affect my Westie’s growth?


There’s some evidence suggesting early spaying/neutering might slightly affect a dog’s growth, possibly leading to taller dogs. Consult your vet for the best timing for your Westie.

19. Why does my Westie puppy sleep so much?


Puppies, like human babies, require a lot of sleep for growth and development. A growing Westie might sleep 18-20 hours a day, which is perfectly normal.

20. Can I give my Westie puppy supplements for better growth?


Before giving any supplements, it’s crucial to consult with a veterinarian. Over-supplementing can be harmful, and a balanced puppy food should provide all the necessary nutrients.
