If your dog or cat has taken a tumble, been hit by a car, or experienced any head trauma, you’re probably worried—and rightfully so. Recognizing pet concussion signs early can make all the difference in your furry friend’s recovery. A concussion is a type of traumatic brain injury that happens when a blow to the head causes the brain to move inside the skull, disrupting normal brain function. Unlike broken bones, concussions aren’t always visible from the outside, which is why knowing what to watch for is so important.

What Is a Pet Concussion?
A concussion occurs when your pet’s brain experiences a sudden impact or jolt that causes it to move within the skull. This movement can temporarily disrupt the way brain cells communicate with each other. The good news? Many pets recover well from mild concussions with proper rest and monitoring. Catching this early puts you in a great position to help.
Concussions can range from mild to severe, and the symptoms may appear immediately or develop over hours. Even if your pet seems fine right after an accident, it’s crucial to watch closely for delayed signs over the next 24 to 72 hours.
Sign #1: Lethargy and Excessive Sleepiness
One of the most common pet concussion signs is unusual drowsiness or lack of energy. Your normally playful pup or active cat might seem unusually tired, wanting to sleep more than usual or showing little interest in activities they normally love.
This lethargy happens because the brain is working hard to heal itself after trauma. While some rest is necessary for recovery, extreme or worsening lethargy warrants immediate veterinary attention. If your pet is sleeping so deeply that you can’t easily wake them, that’s a red flag.
Sign #2: Confusion and Disorientation
Does your pet seem confused or “out of it”? They might walk into walls, get lost in familiar rooms, or stare blankly at nothing. Some owners describe it as their pet acting “dazed” or not quite themselves.
Disorientation after head trauma suggests the brain’s balance and spatial awareness centers may be affected. Your pet might also seem unsure of where they are or fail to recognize familiar family members temporarily. These signs typically improve with rest, but they do require veterinary evaluation.
Sign #3: Vomiting and Loss of Appetite
Nausea and vomiting are frequent companions to concussions in pets. Your dog or cat might refuse their favorite meal, seem interested in food but unable to eat, or vomit shortly after eating. Some pets experience just one episode, while others vomit repeatedly.
Loss of appetite can complicate recovery since your pet needs proper nutrition to heal. If vomiting persists, your vet may recommend anti-nausea support to help your pet feel comfortable enough to eat. Catching this early puts you in a great position to prevent dehydration and malnutrition.
Sign #4: Headaches and Sensitivity to Light or Sound
While pets can’t tell us they have a headache, we can infer one from their behavior. Your pet might flinch when touched on the head, hide in dark corners, or react strongly to normal household sounds like the TV or vacuum cleaner.
Sensitivity to light and sound is a telltale sign of post-concussion discomfort. Some pets will seek out quiet, dimly lit spaces and resist being handled around the head and neck area. Creating a calm, quiet recovery environment is essential during this time.
Sign #5: Loss of Balance and Coordination Issues
After a head injury, your pet might stumble, sway, or have trouble walking in a straight line. They could seem wobbly on their feet, struggle to climb stairs, or bump into furniture more than usual. This loss of balance, called ataxia, indicates the brain’s balance center may be affected.
Watch for tilting of the head, circling behavior, or an inability to stand without swaying. These symptoms typically improve with rest but can persist for days or weeks in more severe cases. Your vet will help determine if additional neurological issues are present.
Sign #6: Behavioral Changes and Mood Shifts
Personality changes after head trauma are surprisingly common. Your usually friendly dog might become irritable or aggressive, while your calm cat could become unusually anxious or clingy. Some pets become withdrawn or show uncharacteristic fear.
These behavioral shifts reflect changes in brain chemistry and inflammation following injury. If aggression or extreme anxiety develops, consult your vet right away, as it may indicate more serious complications. Most behavioral changes improve as the brain heals, but professional guidance helps ensure you’re supporting recovery properly.
Sign #7: Seizures or Tremors
Seizures or muscle tremors are more serious pet concussion signs that require immediate emergency care. If your pet experiences a seizure—characterized by uncontrolled muscle contractions, loss of consciousness, or paddling movements—call your vet or emergency clinic immediately.
Tremors might appear as fine shaking or involuntary muscle twitches. While not all tremors indicate seizure activity, any tremoring after head trauma should be evaluated by a veterinarian. Catching this early puts you in a great position to prevent complications.
When to Seek Emergency Care
Some situations demand immediate veterinary attention rather than waiting for a regular appointment. If your pet experiences any of the following, head to an emergency vet clinic right away:
- Loss of consciousness or inability to wake
- Repeated or continuous vomiting
- Seizures or tremors
- Difficulty breathing
- Bleeding from ears, nose, or mouth
- Severe disorientation or inability to recognize you
- Uncontrolled aggression or extreme behavioral changes
Don’t wait to see if symptoms improve on their own. Emergency vets can perform neurological exams and imaging to rule out life-threatening complications like brain swelling or bleeding.
Recovery Timeline and What to Expect
Most pets recover from mild concussions within a few weeks with proper rest and monitoring. Your vet will likely recommend strict activity restriction—meaning no running, jumping, or rough play during recovery. This gives the brain time to heal without additional stress.
Your pet may need follow-up exams to ensure healing is progressing well. Some pets experience lingering symptoms like mild confusion or sensitivity to stimuli for weeks after the initial injury. Supporting recovery with a calm environment, proper nutrition, and any recommended supplements helps optimize healing.
Supporting Your Pet’s Recovery at Home
Beyond veterinary care, you play a crucial role in your pet’s recovery. Here’s what you can do:
- Create a quiet, safe space: Set up a comfortable area away from loud noises, bright lights, and other pets. This reduces stress on the healing brain.
- Restrict activity: Keep your pet calm and limit exercise as directed by your vet. Even short walks should be on a leash with minimal stimulation.
- Monitor eating and hydration: Offer small, frequent meals and fresh water. If nausea is an issue, discuss supportive care options with your vet.
- Track symptoms: Keep a journal of any symptoms you notice, including when they appear and how long they last. This helps your vet monitor progress.
- Follow vet recommendations: If your vet prescribes any medications or supplements, follow the instructions carefully. Some pets benefit from cognitive support supplements during recovery.
When to Call Your Vet for a Telehealth Consultation
Not every concussion symptom requires an emergency room visit, but many warrant professional evaluation. If you’re unsure whether your pet needs urgent care, a quick telehealth check-in can give you peace of mind—no appointment needed. The Pet Vet’s telehealth service lets you connect with a veterinarian from home, describe your pet’s symptoms, and get guidance on next steps.
Telehealth is especially helpful if your pet is experiencing mild symptoms like lethargy or slight appetite loss, and you’re not sure if they need emergency care. A vet can help you determine whether home monitoring is appropriate or if an in-person exam is necessary.
Frequently Asked Questions
How long does it take for a pet concussion to heal?
Mild concussions typically improve within 1 to 4 weeks with proper rest. Severe concussions may take several weeks to months, and some pets experience lingering symptoms longer. Your vet will give you a timeline based on your pet’s specific injury.
Can a pet concussion cause permanent brain damage?
Most mild to moderate concussions don’t cause permanent damage, especially with prompt care. Severe concussions or repeated head injuries increase the risk of lasting effects, which is why early veterinary evaluation is so important.
Should I take my pet to the vet if they seem fine after hitting their head?
Yes. Concussion symptoms can develop over hours or days, so even if your pet seems okay immediately after the injury, a vet should evaluate them. This ensures no serious complications are developing.
What’s the difference between a concussion and a head injury?
A head injury is any trauma to the head, while a concussion is a specific type of head injury involving temporary brain dysfunction. Not all head injuries result in concussions, but all concussions involve head trauma.
Can I treat a pet concussion at home without seeing a vet?
You cannot diagnose a concussion at home or rule out serious complications like brain bleeding. Professional veterinary evaluation is essential to ensure your pet receives appropriate care and monitoring during recovery.
What To Do Now
If you suspect your pet has experienced head trauma, take these steps immediately:
- Call your veterinarian or emergency clinic right away to describe the incident and ask whether your pet needs to be seen. Don’t wait to see if symptoms develop.
- Keep your pet calm and confined to a safe space while awaiting veterinary guidance. Avoid handling them roughly or allowing them to play.
- Monitor closely for the next 72 hours and note any changes in behavior, appetite, energy levels, or coordination. Write down when symptoms appear and how long they last.
- If you’re unsure about severity, schedule a telehealth consultation with The Pet Vet for professional guidance on whether in-person care is needed.
- Follow all post-examination recommendations from your vet, including activity restrictions and any prescribed medications or supplements.
