Causes Of Staggering Or Stumbling
Infectious diseases: Distemper; rabies; other bacterial, viral, or fungal diseases that cause meningitis or encephalitis; otitis interna (bacterial, fungal/yeast infection secondary to otitis externa). Note: Never handle a dog who may have rabies. If possible, without touching the dog, confine him in a room, pen, or yard and call your local animal control for assistance.
Toxicity: Metaldehyde (slug bait), anticoagulant rodenticides such as warfarin, bromethalin (rodenticide), or ANTU (rodenticide); bread dough; alcohol; ethylene glycol, or lead.
Congenital/Inherited disorders: Intervertebral disk disease (in Dachshunds, Pekingese, Beagles, and other small breeds); caudal cervical spondylomyelopathy (“wobbler syndrome” in Borzois, Basset Hounds, Doberman Pinschers, Great Danes); degenerative myelopathy (in German Shepherd Dogs, Welsh Corgis); degenerative lumbosacral stenosis (in German Shepherd Dogs); vertebral malformations; ataxia of Jack Russell Terriers and Smooth Fox Terriers; atlantoaxial subluxation (in toy and miniature breeds, occasionally in Doberman Pinschers, Rottweilers, and other large breeds); or spinal muscular atrophy.
Tumors: In brain or pancreas.
Nutritional: Hypoglycemia or puerperal hypocalcemia (decreased blood calcium level during lactation).
Drug reactions: Ivermectin (in sheepdog breeds), ibuprofen, chlorpheniramine (antihistamine; large amounts), naproxen, or mitotane, a medication used to treat hyperadrenocorticism (Cushing’s disease) or adrenal tumors.
Parasites/Parasite-borne diseases: Chronic ehrlichiosis or tick paralysis.
Endocrine disorders: Hypoparathyroidism.
