Shelties, also known as Shetland Sheepdogs, are charming, intelligent, and versatile dogs, adored by many for their striking appearance and lively personality. But given their herding background and sometimes reserved nature, potential Sheltie owners or those unfamiliar with the breed might wonder about their bite force and if it can cause pain. In this deep dive, we will explore the biting power of the Sheltie and determine just how much of a bite this small to medium-sized dog can deliver.

Understanding the Bite Force Metrics: How Does the Sheltie Compare?

Bite force in dogs is typically measured in pounds per square inch (PSI). While a Sheltie is far from the top when it comes to the strongest bite forces in the dog world, they do have a moderate bite for their size. Generally, the bite force of a Sheltie ranges around 90-115 PSI. To give some context, this is significantly less than the bite force of larger breeds but still potent for a dog of the Sheltie’s stature.

The Sheltie’s Jaw Structure: Built for Function, Not Aggression

When examining the Sheltie’s jaw structure, it’s evident that their bite developed for function, particularly in line with their herding background. Shelties were bred to herd and sometimes nip at the heels of larger animals to keep them in line. Their jaws are strong enough to allow them to effectively nip when needed, but not so powerful that they could severely harm the livestock they were herding.

Does a Sheltie’s Bite Hurt?

Given the bite force statistics and the function-driven jaw structure, it’s reasonable to conclude that a bite from a Sheltie, especially if done with intent, can indeed hurt. Their bite force is enough to cause pain and potentially break the skin. It’s always crucial, no matter the breed, to approach any dog with caution, particularly in situations where they might feel threatened or scared.

Why Might a Sheltie Bite?

Shelties, while generally amiable and good-natured, might bite for several reasons:

  • Herding Instinct: As mentioned, Shelties were bred to herd, and sometimes, this instinct can lead them to nip, especially at fast-moving objects, including children at play.
  • Fear or Anxiety: Shelties can be a bit reserved, especially with strangers. If they feel cornered or threatened, they might bite in defense.
  • Pain or Discomfort: Like all dogs, a Sheltie might bite if someone touches a sore spot or if they’re feeling unwell.
  • Resource Guarding: Some Shelties might be possessive of their food, toys, or territory and could nip if they feel someone is trying to take their belongings.

Understanding these potential triggers can help in preventing unwanted biting incidents. Proper training and early socialization are critical in curbing these behaviors.

Training and Socialization: Reducing Nipping and Biting in Shelties

One of the most effective ways to ensure your Sheltie does not resort to unwanted biting or nipping is through training and socialization. Here are a few steps tailored for Shelties:

  1. Early Exposure: Expose your Sheltie to various environments and people when they’re young to build their confidence and reduce anxiety.
  2. Redirect Herding Behavior: If your Sheltie tends to nip at heels or chase, redirect this behavior towards toys or agility-based activities.
  3. Consistent Commands: Teaching commands like “stop” or “no” can help curb unwanted behaviors.


The Sheltie does possess a bite force that can cause pain if used with intent. Given their herding background, they might occasionally exhibit nipping behavior, particularly during play or when they feel threatened. However, with proper understanding, training, and socialization, Shelties prove to be loving, loyal companions whose bites are far less frequent than their barks.


Frequently Asked Questions About Sheltie Bites

1. Are Shelties naturally aggressive or prone to biting?

Shelties are not naturally aggressive, but they do have a herding instinct that may lead them to nip or “herd” moving objects, including people, especially children. Proper training and socialization can help mitigate this behavior.

2. Why does my Sheltie nip at people’s heels?

The Sheltie’s herding background is responsible for this behavior. They were bred to herd livestock and would nip at the heels of sheep to guide them. While it’s instinctual, this behavior can be redirected or minimized with training.

3. How can I train my Sheltie to stop biting during play?

Positive reinforcement and redirection are key. When your Sheltie nips or bites during play, stop the game immediately, redirect their attention to a toy or chew, and reward them when they engage with the appropriate items without nipping.

4. Is a Sheltie’s bite strong enough to break the skin?

Yes, despite their moderate bite force, a Sheltie’s bite can break the skin, especially if they bite with intent. It’s essential to approach any situation where a dog might feel threatened with caution.

5. Why does my Sheltie growl or snap when I try to take their toy?

This behavior is known as resource guarding. Your Sheltie might be possessive over their belongings and feel the need to protect them. Training, desensitization, and teaching the “drop it” or “leave it” command can help address this issue.

6. Are Shelties more likely to bite strangers than family members?

Shelties can be reserved or wary of strangers. If they feel threatened or cornered by someone unfamiliar, they might snap or bite. Early socialization and introducing them to various people can help reduce this behavior.

7. My Sheltie puppy bites a lot. Will they grow out of it?

Puppy biting or mouthing is a common behavior, and many puppies, including Shelties, will exhibit it. While some outgrow it, it’s essential to address the behavior through training to ensure it doesn’t persist into adulthood.

8. How do I socialize my Sheltie to reduce the risk of biting?

Expose your Sheltie to different environments, sounds, people, and other animals from a young age. Positive experiences, rewards for calm behavior, and consistent training are integral parts of effective socialization.

9. Are male or female Shelties more prone to biting?

There isn’t conclusive evidence to suggest that one gender is more prone to biting than the other. Individual temperament, training, socialization, and environment play more significant roles in biting behavior than gender alone.

10. How effective are bite inhibition exercises with Shelties?

Bite inhibition exercises can be highly effective with Shelties. By teaching them to control the force of their bite from a young age, it ensures safer interactions as they grow, especially in situations where they might mouth or nip playfully.
