Abstract Thiamine (vitamin B 1 ) is an essential nutrient that significantly influences ATP production in the body. It needs to be supplemented consistently through an exogenous source to prevent deficiency; however, it is easily affected by a variety of mitigating factors. Additionally, thiamine requirements can be influenced by an individual's dietary composition. The nervous system is particularly vulnerable to thiamine deficiency due to its high metabolic demand. Thiamine deficiency is typically diagnosed based on clinical signs, dietary history and response to thiamine administration. A 5‐year‐old neutered male Maltese Terrier dog presented with an acute onset of seizures and generalized ataxia. The dog was exclusively fed boiled sweet potato ( Ipomoea batatas ) as a primary diet source for 4 weeks. MR findings and hyperlactatemic conditions were consistent with thiamine deficiency, and the diagnosis was confirmed by measuring thiamine concentrations in blood using high‐performance liquid chromatography (HPLC). Appropriate thiamine supplementation and diet changes resulted in a rapid improvement in neurological signs. Repeated MR imaging 2 weeks after starting the treatment completely resolved the previously identified abnormalities, and repeated measurements of blood lactate and thiamine levels revealed complete recovery of the thiamine‐deficient status.
