The other half of cases can be caused by many factors, including allergies, infections, and some forms of cancer.Usually this condition affects only the skin, but internal organs may also be affected in some cases. If you see the signs in your dog, then you should consult your veterinarian for a proper diagnosis and treatment.Here’s what you should know about the symptoms, causes, and treatments for cutaneous vasculitis in dogs.Symptoms Of Cutaneous Vasculitis In Dogs (Picture Credit: Getty Images)The symptoms of cutaneous vasculitis in dogs are visible on the skin.

Vets refer to this as idiopathic cutaneous vasculitis. The main cause of the symptoms is an abnormal immune system response, which can happen due to a number of reasons.Here are several conditions that can cause immune system abnormalities that lead to cutaneous vasculitis:Bacterial or viral infectionsInternal cancerReaction to vaccine (often the rabies vaccine)Food allergiesTick-borne illnessesSome dog breeds are more predisposed to developing cutaneous vasculitis. These include Chinese Shar Peis, Collies, Dachshunds, German Shepherd Dogs, Greyhounds, Jack Russell Terriers, Rottweilers, Saint Bernards, and Shetland Sheepdogs.Some breeds are more prone to developing the condition due to a reaction from vaccination, including Maltese Terriers, Poodles, Silky Terriers, and Yorkshire Terriers.Treatments For Cutaneous Vasculitis In Dogs (Picture Credit: Getty Images)Treatment for cutaneous vasculitis in dogs usually depends on the underlying cause of the condition. For example, if the vet suspects infection, then they may prescribe antibiotics to help fight off the bacteria. If food allergies are the cause, then the vet may prescribe dietary changes.Most dogs who suffer from cutaneous vasculitis must also take anti-inflammatory drugs and immunosuppressive medications to control the abnormal immune response. The types of medication depend on the severity of the skin condition and whether or not internal organs have been affected.When vets can’t find or treat the underlying cause of the condition, medication may need to be given for the rest of dogs’ lives.Has your dog ever suffered from cutaneous vasculitis?
