Dysautonomia canine

OBJECTIVE: To retrospectively describe ocular abnormalities reported in dogs with presumed dysautonomia. ANIMALS: 79 dogs with dysautonomia. METHODS: Medical records from the Kansas State University Veterinary Health Center from 2004 to 2021 were reviewed for dogs with a clinical or histopathologic diagnosis of canine dysautonomia (CD). Ophthalmic exam abnormalities, nonocular clinical signs, and outcomes were recorded. RESULTS: Most dogs (73/79 [92...

Background/Aims: Gastroparesis is commonly seen in patients with diabetes and functional dyspepsia with no satisfactory therapies. Dysautonomia is one of the main reasons for the imbalanced motility. We hypothesized that spinal cord stimulation (SCS) is a viable therapy for gastroparesis via the autonomic modulation to improve gastric motility. The aim is to find an optimal method of SCS for treating gastroparesis. Methods: Eight healthy-female dogs were implanted with a gastric cannula, a duodenal cannula, 2 multi-electrode spinal leads, and an implantable pulse generator...

Canine dysautonomia is a sporadic, generally fatal disease that rarely affects groups of related animals. Four 10-week-old Havanese puppies from a litter of 5 developed clinical signs of canine dysautonomia. The 4 affected dogs were exposed to an outdoor environment, whereas the fifth littermate was not exposed to the outdoors and remained clinically healthy. Clinical signs of dysautonomia developed 10-16 days after going outside the house. An unrelated dog also developed dysautonomia after exposure to 1 of the affected Havanese littermates...

Canine dysautonomia was diagnosed definitively in five dogs by histopathology. All dogs were seen between June 2004 and July 2006 and originated from south-east England; four dogs originated from an urban area and one from a rural area. Of the urban dogs, one had recently visited Scotland and one had visited a kennel in a rural area nearby. Acute-onset but progressive vomiting, diarrhoea, depression and inappetence were the most common presenting clinical signs. Reduced or absent anal tone, dysuria, absence of pupillary light reflexes with intact vision, mydriasis, decreased corneal sensitivity and nictitating membrane protrusion were among the most frequent neurological findings...

A cross-sectional survey of 217 veterinary facilities in Missouri, USA, was conducted to gather information about the occurrence of canine dysautonomia between January 1996 and December 2000. The state was divided into seven geographic regions for sampling, and 40 veterinary facilities from each region were selected randomly by computer-generated numbers to receive the questionnaire. Veterinarians from 74% (95% CI: 69, 79) of clinics in the state that saw canine patients were aware of dysautonomia prior to receiving the survey, and 43 respondents from five of the seven sampled regions stated that dysautonomia had been diagnosed in their practices during the study period...

Two clinical cases of canine dysautonomia are described. Two young female neutered dogs were presented with clinical signs including vomiting, diarrhoea, faecal tenesmus, dysphagia and urinary retention. Decreased tear production, dry mucous membranes, bilateral Horner's syndrome, decreased anal sphincter tone and gastrointestinal hypomotility were also observed. Presumptive diagnoses of dysautonomia were made based on the clinical presentation and investigations. Postmortem histopathological examination in one of the cases demonstrated marked depletion of neuronal cell bodies in the intestinal myenteric plexuses and parasympathetic ganglia, confirming the diagnosis in this case...

Canine dysautonomia is an idiopathic condition resulting in loss of autonomic nervous system function. Recently, the prevalence of dogs diagnosed with dysautonomia in the mid-western United States has increased. In this study the medical records and radiographic findings in 24 dogs with dysautonomia were reviewed. A diagnosis of dysautonomia was made in 17 (71%) of the dogs in this study by postmortem examination, the remaining 7 (29%) dogs were diagnosed pharmacologically. The radiographic findings supportive of dysautonomia include aspiration pneumonia, megaesophagus, or a distended stomach, small bowel, or urinary bladder...
