Why Your Dog Arches His Back Like a Cat?

Have you ever wondered why your dog arches his back like a cat? Sometimes it’s nothing to worry about, but other times it’s a sign that your dog is in pain.

Dogs may arch after a nap, during play, or when stretching — all of which are normal. But the same posture can also mean problems like stomach pain, spine issues, or anal sac trouble.

This guide will outline the 7 main reasons dogs arch their back, how veterinarians diagnose the cause, available treatment options, and the red flags you should never ignore.

7 Reasons Dogs Arch Their Back

Cause	What You’ll See	How Serious
Normal Stretching	After sleep or play, relaxed dog	Normal
Stomach Pain / Bloat	Drooling, swollen belly, restless	Emergency
Anal Sac Issues	Stiffness, weak legs, can’t move well	Needs vet care
Spinal Problems (IVDD)	After sleep or play, a relaxed dog	Emergency
Muscle Strain	After jumping or running	Mild
Nervous System Problems	Wobbling, seizures, balance loss	Emergency
Organ Pain (kidney, pancreas)	Vomiting, no appetite, tired	Needs vet care

1. Normal Stretching

The most common reason for dogs arching their back is simple stretching. After waking up, during play, or before running, dogs often stretch their spine. This pose sometimes looks like the “cat stretch” or “play bow.”

If the stretching is short, relaxed, and followed by normal movement, it’s nothing to worry about.

2. Stomach Pain or Bloat

Another reason is belly pain. Gas, indigestion, or even life-threatening bloat (GDV) can make your dog arch and hunch.

Warning signs of bloat:

Bloat is an emergency. If you see these signs, rush to the vet immediately.

3. Anal Sac Issues

Dogs have two small glands near the anus. If they get blocked or infected, your dog may arch his back to ease the discomfort.

Other symptoms include:

Treatment usually involves manual cleaning, antibiotics, or sometimes minor surgery.

4. Spinal Problems (IVDD)

One of the most serious causes is intervertebral disc disease (IVDD) or other spine problems.

Look for these signs:

Vets may use X-rays, CT scans, or MRI to confirm. Treatment may include rest, medications, or surgery. If your dog suddenly can’t walk, it’s an emergency.

5. Muscle Strain

Just like humans, dogs can pull a muscle while running, playing, or jumping. They may arch their back for a short time to protect the sore spot.

In most cases, rest and gentle care help. If the pain persists for more than a few days, consult your veterinarian for further evaluation.

6. Nervous System Problems

Sometimes the issue is not the muscles or the stomach, but the nervous system. Conditions such as meningitis, brain tumours, or nerve pressure can affect posture.

Other signs include:

These are medical emergencies. Immediate vet care is needed.

7. Organ Pain (Kidneys, Pancreas, etc.)

Internal organ problems may also cause a hunched back. Common culprits include:

• Kidney infections
• Pancreatitis
• Bladder stones

Other symptoms:

• Vomiting
• No appetite
• Drinking or peeing more than usual
• Tiredness

Vets may run blood tests, urine tests, and ultrasounds to find the problem.

How Vets Find the Cause

This step-by-step testing helps find the exact reason behind the arching.

Treatment & First Aid

The treatment depends on the cause:

• Muscle strain → Rest + anti-inflammatory medicines
• Anal sac issues → Cleaning, antibiotics, or surgery
• Stomach pain/bloat → Diet change, fluids, or emergency surgery
• IVDD → Rest, pain medicine, or spinal surgery
• Organ pain → Hospital care, IV fluids, special diet

At home: Keep your dog calm by avoiding activities that cause them to jump or run, and never give them human medicine unless your veterinarian has prescribed it.

When to Rush to the Vet

Take your dog to the vet immediately if you notice:

These are life-threatening emergencies.

Prevention Tips

You can’t prevent all problems, but you can lower risks:
Keep your dog at a healthy weight
Use ramps instead of letting them jump from heights
Give gentle daily exercise
Schedule regular vet checkups
Pay attention to posture changes
