Juvenile Polyarteritis (Beagle Pain Syndrome) in Dogs: Symptoms, Causes, & Treatments

Juvenile polyarteritis in dogs is a rare condition that involves the arteries inflaming and an infection of the spinal cord. It affects certain breeds of dogs more than others, and people often refer to it as Beagle pain syndrome.

Vets most commonly diagnose the condition in dogs under the age of three years old. It can often be noticed by a dog affecting a hunched posture.

If you see signs that your dog might be suffering from this condition, then you must consult your veterinarian for a proper diagnosis and course of treatment. Here’s what you should know about the symptoms, causes, and treatments of juvenile polyarteritis in dogs.

Symptoms of juvenile polyarteritis in dogs

Juvenile polyarteritis in dogs can result in a number of symptoms. Veterinarians and pet parents most often start to suspect the condition when a dog adopts a hunched over posture. If your dog takes on an unusual posture, then you should consult your vet.

Some of the most common symptoms of the condition include:

  • Having a hunched back
  • Lowering their head
  • Pain in the neck (including a stiff neck)
  • Lower than usual appetite
  • Acting lethargic
  • Becoming less mobile
  • Fever
  • Reluctance to bark

Juvenile polyarteritis in dogs is a condition that seems to be genetic. In some cases, vets suspect auto-immune issues as a partial cause.

Although the condition is commonly known as Beagle pain syndrome, it also affects other breeds of dog, including Bernese Mountain Dogs and Boxers.

Treatments for juvenile polyarteritis in dogs

If you think that your dog might be developing juvenile polyarteritis, your veterinarian will want to carry out a full physical examination of your dog. At first, it is important to rule out other conditions, including cervical disc disease, spinal tumors, and issues affecting the vertebral discs.

Vets can also find blood tests useful in diagnosing the condition, along with the use of a spinal tap in some cases.

When providing treatment, vets usually prescribe anti-inflammatory drugs. They can also use steroids during the early stages of treatment. As always, if your vet prescribes a course of medicine for your dog, it is vital that you stick to the precise dosage and frequency instructions, along with completing the full course of medication.

While your dog is recovering at home, it is important that you provide a quiet, calm, and isolated space. You should also keep an eye out for any signs of a relapse and consult with your vet if previous symptoms seem to return.
