Intervertebral Disc Disease (IVDD) is a degenerative disease that can affect your dog's spinal cord and causes a range of painful mobility issues. What is IVDD? Intervertebral disk disease (IVDD) in dogs can also be described as a ruptured, slipped, bulging or herniated disk. This condition is most commonly seen in beagles, dachshunds, Pekingese, Shih Tzus, basset hounds, or American cocker spaniels but may occur in dogs of any breed.  What causes IVDD in dogs? Intervertebral Disc Disease is an age-related, gradual degenerative process that affects the spinal cord of the dog over a period of time, often undetected. Even with yearly wellness exams, your vet may not detect any signs of IVDD until your dog's hardened disc or discs become ruptured and painful symptoms become evident. Something as every day as a jump up onto the sofa could damage a disc that has been weakened by IVDD, and trigger acute and painful symptoms of the disease. IVDD occurs when the shock-absorbing discs between your dog's vertebrae gradually begin to harden until they are unable to cushion the vertebrae properly. The hardened discs will typically go on to bulge and compress the spinal cord, often damaging the dog's nerve impulses such as those that control bladder and bowel control. In other cases, a simple jump or poor landing can lead one or more of the hardened discs to burst and press into the nerves of the dog's spinal cord causing pain, possible nerve damage or even paralysis. What are the symptoms of IVDD in dogs? Intervertebral Disc Disease can occur in any of the discs in your dog's spine and symptoms of this condition will depend upon which part of the spine is affected, and how severe the damage is. Symptoms of IVDD may also appear suddenly or come on gradually. If your dog is displaying any of the following symptoms seek veterinary care as soon as possible. IVDD can be very painful for dogs and early treatment is essential for preventing the condition from becoming more severe or causing irreversible damage to your dog's spine.  Symptoms of Neck Intervertebral Disc Disease (Cervical IVDD) Cervical IVDD occurs in the discs of the dog's neck. If you may notice one or more of the following symptoms, which can affect the whole body and range from mild to very severe contact your vet for immediate advice, or visit your closest animal emergency hospital for veterinary care: Head held low Arching back  Shivering or crying Reluctance to move Unsteadiness in all 4 legs Inability to walk normally Knuckling of all 4 paws Inability to support own weight Inability to stand Inability to feel all 4 feet and legs Symptoms of Back Intervertebral Disc Disease (Thoracolumbar IVDD) Dogs with Thoracolumbar IVDD have a damaged disc causing issues in their back region and may display one or more of the following symptoms. Symptoms of Thoracolumbar IVDD mainly affect the mid to back portion of the dog's body and can range from mild to very severe: Muscle spasms Tense belly  Weakness in hind legs Crossing back legs when walking Inability to walk normally Knuckling of back paws, or dragging rear legs Inability to support their own weight Unable to move or feel back legs Symptoms of Lower-Back Intervertebral Disc Disease (Lumbosacral IVDD) If your dog is suffering from lumbosacral IVDD the problematic disc or discs are located in your dog's lower back region. Symptoms of lumbosacral IVDD typically affect the very back of the dog's body and may range from mild to very severe: Pain and/or difficulty jumping Limp tail Urinary or fecal incontinence Dilated anus How is IVDD diagnosed in dogs? If your dog begins showing any of the above symptoms immediate veterinary care is required. Tests for diagnosing Intervertebral Disc Disease typically include standard x-rays, a neurological exam, and/or MRI to help locate the disc or discs causing your dog's symptoms.
