Dog Arching Back: Causes and Solutions

If you've ever noticed your dog arching their back, you might wonder what could be causing this behavior. While occasional arching of the back is normal, especially during stretching or play, persistent or exaggerated arching could indicate an underlying health issue that needs attention. Understanding the potential causes and appropriate responses can help ensure your furry friend stays happy and healthy.

Why is My Dog's Back Arched?

A dog's back may arch for various reasons, some of which are normal and others abnormal. Here are some potential causes:

Normal Causes

• Stretching: Dogs often arch their backs as part of their natural stretching behavior. This is similar to how humans stretch to relieve tension in their muscles.
• Playfulness: During play, dogs may arch their backs as they engage in various movements and postures. This is typically not a cause for concern unless it is accompanied by signs of discomfort or pain.
• Defensive posture: In some cases, a dog may arch its back in a defensive posture, especially when feeling threatened or intimidated. This is a natural instinct designed to make the dog appear larger and more intimidating to potential threats.

 

Abnormal Causes

• Muscle strain or injury: Just like humans, dogs can experience muscle strains or injuries that cause discomfort and lead to arching of the back.
• Spinal problems: Conditions such as intervertebral disc disease (IVDD) or spinal arthritis can cause pain and stiffness, prompting dogs to adopt a hunched posture.
• Digestive issues: Dogs experiencing gastrointestinal discomfort, such as bloating, constipation or parasites, may arch their backs in an attempt to alleviate the discomfort.
• Urinary tract problems: Conditions like urinary tract infections or bladder stones can cause discomfort, prompting dogs to arch their backs while urinating.
• Anal Sac Disorders: Anal sac disorders can occur as impaction, infection, or abscess of the anal sac. Your dog needs to be able to express fluid from his anal glands. If the fluid cannot be released, the impacted fluid inside the anal glands creates increasing tension, causing the dog to tilt his hindquarters down to relieve the tension. When the dog’s hindquarters are tilted down, his back may be arched. Any dog can develop an anal sac disorder.

What to Do If Your Dog is Arching His Back?

If you observe your dog arching back persistently or displaying signs of discomfort, it's essential to take proactive steps to address the issue. Here's what you can do:

Monitor your dog

Your dog’s nausea signs should be carefully watched, and you should withhold food and water to see if the signs subside. Signs may resolve within 2-3 hours, but if not your dog should receive a veterinary assessment.

 

Medicines

Parasites can often be resolved with a short course of oral medication. 
Minor gastrointestinal upset can be treated with anti-emetic tablets.
If it is a urinary tract infection, it can be treated with hydrochlorothiazide.

Bloating

Unlike nausea, there is no easy case of gastric dilatation-volvulus. Gastric dilation-volvulus (GDV), also known as bloat, is a serious and potentially life-threatening condition that primarily affects large and deep-chested dog breeds. In GDV, the stomach becomes distended with gas and fluid, and then it may twist or rotate on its axis, leading to obstruction of blood flow to the stomach and other vital organs. GDV is considered a medical emergency and requires immediate veterinary attention. 

Prompt diagnosis and treatment, often involving decompression of the stomach, stabilization, and surgical correction of the torsion, are necessary to improve the chances of survival. GDV can progress rapidly and lead to shock, organ damage, and death if left untreated.

Intervertebral disc disease (IVDD)

Intervertebral disc disease (IVDD) can vary in severity, and treatment options will depend on the specific situation. Mild cases of IVDD may respond well to conservative management, which can include rest, anti-inflammatory medications, pain management, and physical therapy.

However, more severe cases of IVDD, especially those that result in neurological deficits such as paralysis or loss of bladder and bowel control, often require surgical intervention.

Here are examples of ingredients commonly found in anti-inflammatory or corticosteroid drugs used to manage spinal disorders like intervertebral disc disease:

Nonsteroidal anti-inflammatory drugs (NSAIDs):

• Carprofen
• Meloxicam
• Rimadyl
• Previcox
• Etodolac

Corticosteroids (steroids):

• Prednisone
• Prednisolone
• Dexamethasone
• Triamcinolone

How Do I Know If My Dog Has Hurt Their Back?

Here are some common signs that may indicate a back injury in dogs:

• Changes in posture: Your dog may exhibit an arched or hunched back, especially if they are experiencing pain in the spinal area.
• Reluctance to move: Dogs with back pain may be hesitant to move or may have difficulty getting up, sitting down, or climbing stairs.
• Lameness or weakness: You may notice limping or weakness in one or more limbs, particularly if the back injury has affected nerve function.
• Vocalizations: Your dog may whimper, whine, or yelp in response to movement or when touched in certain areas of the back.
