Abstract

A free-range wild raccoon dog (Nyctereutes procyonoides) was rescued with cachexia. Physical examination revealed generalized hyperkeratosis and alopecia typical of scabies as well as hypothermia (35.6℃). The patient was obtunded and severely dehydrated (10%). Hematological parameters included a low packed cell volume (PCV; 15%) and hemoglobin concentration, leukocytosis, and hypoglycemia. A blood smear revealed different subtypes of hypochromic leptocytes, indicating a regenerative response against severe anemia. This case was initially tentatively diagnosed as a severe anemia due to chronic external bleeding presumed to be caused by scabies-induced skin injuries. Darbepoetin alpha (DPO), iron dextran, and fluralaner were administered at the initial presentation, and supportive care including oxygen supplementation, warming, and nutritional support was provided. However, on day 5, the PCV dropped to 5.9% presumably caused by rapid rehydration due to drinking water ad libitum. DPO was boosted on days 5 and 6 along with daily iron dextran. On day 21, the PCV had recovered to 19.8%, and a blood smear evaluation showed a strong regenerative response. This case shows that even if severe anemia occurs in a raccoon dog, it can be managed with an appropriate response. In particular, since the rehydration rate due to food intake is faster than the hematopoietic response rate of raccoon dogs, the PCV may decrease rapidly in the early stage of treatment; therefore, diagnostic examination and additional medical management for hematopoiesis are necessary.
