Scratching and Other Stress Behaviors: Is Your Dog Stressed or Just Excited

If you’ve ever watched a dog agility competition, you’ve probably seen it happen: a dog is vibrating with excitement at the start line, ready to explode down the course. Then, suddenly, they stop, turn away from their handler, and scratch furiously.

They don't have a sudden itch. That scratching is actually a sign of stress.

But here’s the thing—stress isn’t always negative. Just like us, dogs feel pressure and anticipation about things they absolutely love. In the dog world, this sudden out-of-context scratching is called a displacement behavior. It's the canine equivalent of a human twiddling their thumbs or tapping their foot when they're anxious or excited.

While this happens in all kinds of dog sports, most handlers know exactly what’s going on. They patiently wait for the dog to reset, get their attention back, and get on with the game. It’s not a big deal; it's just part of life.

New Stuff Can Be Stressful

We see this all the time in our training classes. Every time we introduce a brand-new game, at least a few dogs will start scratching or showing other subtle signs of anxiety.Dog Behavior

Even dogs who love training get a little nervous around new things. It’s not because they are frightened; it's because they don’t know what they’re supposed to do yet. Dogs genuinely want to get things right. Even if a dog has never been punished a day in their life, they can still worry about doing the "wrong" thing.

Scratching is just one way they process that confusion. Other subtle "thinking it over" signs include:

• Lip-licking (when there is no food around.
• Yawning (when they aren't tired)
• Disengaging or turning away
• Offering "safe" behaviors (offering a sit or down they know gets rewards, just to see if it works)

Know the Difference: Excited vs. Frightened

Dogs are excellent communicators, but their signals change depending on how deep the stress goes. As a dog owner, it helps to know the difference between a dog who is just overwhelmed by a game, and a dog who is genuinely uncomfortable.

If a dog is frightened, overwhelmed, or feeling trapped, the signals become much more protective:

• “Whale eye” (where you can see the whites of their eyes)
• Flattened ears pinned back against the head
• A tucked tail or a low, stiff wag
• A hunched back and rigid posture
• Raised hackles (the hair standing up along their spine)

Listen to Your Dog’s Body Language

If you see minor stress signals like scratching during a training session, don't worry. Just lower the criteria, make the game a little easier, and help them succeed.

However, if you see the more serious signs of fear or discomfort, it’s time to advocate for your dog and remove them from the situation.

We often see heartbreaking stories in the news about "sudden" negative interactions between dogs and children. Most of the time, the adults claim there was absolutely no warning. But if you look at the photos or videos leading up to those moments, the dogs are almost always screaming for help with their body language—showing whale eye, licking their lips, or turning their heads away.

By recognizing these signs early, you can protect your dog, build their confidence, and keep your training sessions fun, safe, and successful for everyone involved.
