From Hyper to Happy: How Diet Can Reduce Hyperactivity in Dogs

ByJosh Wilson

If your dog is bouncing off the walls, barking excessively, or constantly seeking stimulation, you’re not alone. Many dog owners struggle with managing hyperactivity, especially in young or high-energy breeds. While training and exercise are essential for behavior management, one often-overlooked factor can have a significant impact: diet.

What your dog eats affects not just their physical health, but also their mental state and behavior. In fact, poor diet can be a hidden cause of restlessness, impulsiveness, and difficulty focusing. The good news is that the right nutrition can help transform an overstimulated, anxious dog into a calmer, more focused companion.

Understanding Hyperactivity in Dogs

Hyperactivity in dogs isn’t always a medical issue — it’s often a behavioral response to unmet needs or dietary imbalances. Common signs include:

  • Inability to settle or relax

  • Excessive barking or whining

  • Constant pacing or jumping

  • Short attention span

  • Overexcitement around people or other dogs

If your dog is otherwise healthy and receiving adequate exercise, the next place to look is their food bowl.

How Diet Influences Canine Behavior

Food fuels the body and brain. The ingredients in your dog’s diet directly influence hormone production, neurotransmitter activity, and energy regulation. Just like a child on a sugar high, a dog’s mood and behavior can shift dramatically based on what they’re consuming.

Here’s how diet can either aggravate or help reduce hyperactive behavior:

1. Blood Sugar Spikes and Crashes

Many commercial dog foods are loaded with simple carbohydrates like white rice, corn, and wheat. These ingredients can cause rapid spikes in blood sugar, followed by crashes — which may trigger anxious or excitable behavior.

What helps:
Choose foods with low-glycemic, complex carbohydrates like sweet potatoes, lentils, and oats. These provide slow-burning energy that helps regulate mood and reduce erratic energy swings.

2. Protein Quality and Quantity

Too much low-quality protein or the wrong kind of protein can overstimulate some dogs, particularly if it’s heavily processed or derived from unidentified meat sources. On the other hand, high-quality, digestible animal proteins help support balanced neurotransmitter production — especially serotonin, which promotes calmness and well-being.

What helps:
Look for diets with named animal proteins (e.g., chicken, turkey, salmon) as the primary ingredient and avoid by-products or mystery meats. Moderating protein intake in certain hyperactive dogs (under vet guidance) can also be beneficial.

3. Artificial Additives and Preservatives

Some dogs are sensitive to artificial colors, flavors, and chemical preservatives — many of which can act as stimulants or allergens. These additives are more common in lower-cost commercial dog foods and treats.

What helps:
Feed a clean, natural diet free from synthetic additives. Focus on whole-food ingredients with minimal processing.

4. Omega-3 Fatty Acids and Brain Health

Omega-3 fatty acids, particularly DHA and EPA from fish oil, support cognitive function, reduce inflammation, and have natural calming effects. Dogs low in omega-3s may be more prone to anxiety, hyperactivity, or poor focus.

What helps:
Incorporate a high-quality fish oil supplement or choose food rich in salmon, sardines, or flaxseed.

5. Micronutrients That Promote Calmness

Certain vitamins and minerals help regulate mood and stress response:

  • B vitamins: Vital for nervous system health

  • Magnesium: Helps with muscle relaxation and mood stabilization

  • Tryptophan: An amino acid that supports serotonin production

What helps:
Select foods or supplements that include calming nutrients, or ask your vet about adding a balanced multivitamin designed for behavioral support.

Additional Tips for a Calmer Dog Through Diet

  • Avoid high-sugar treats: Many commercial treats are loaded with sugar and starch. Choose single-ingredient or protein-rich snacks.

  • Establish a feeding routine: Feeding at the same times each day can help regulate energy levels and behavior.

  • Try calming supplements: Products with chamomile, L-theanine, or melatonin (vet-approved) can aid relaxation, especially during stressful periods.

When to See a Vet or Behaviorist

If your dog’s hyperactivity is extreme, persistent, or paired with aggression or compulsive behavior, consult a veterinarian or certified behaviorist. In some cases, hyperactivity could signal a medical issue like hyperthyroidism or an anxiety disorder that requires professional attention.
