(eg. description of the frequency and severity of the symptoms

On January 8, 2019, the owner saw the dog ingest an unknown amount of this product. Soon after, the dog developed tremors, hypersalivation, respiratory crackles (fluid sound in the lungs), and inappropriate defecation. At an unknown date and time, the owner took the dog to the emergency veterinarian. The emergency veterinarian then contacted the Animal Product Safety Service (APSS). The emergency veterinarian stated that dog's heart rate was normal at 100.0 beats per minute (bpm). The APSS veterinarian stated that methomyl is a carbamate that is rapidly absorbed after ingestion, but does not accumulate in the tissues and that it does not "age" on the receptors like organophosphates (OP's) do, so signs are often short-lived. The APSS veterinarian also stated that signs occur within minutes after ingestion, and include salivation, lacrimation, urination, diarrhea, dyspnea, and emesis (SLUDDE) signs, bradycardia, ataxia, weakness, tremors, seizures, and possibly death. Finally, the APSS veterinarian stated that if not a lethal exposure, signs are expected to resolve spontaneously due to the reversible nature of carbamate toxicity. The APSS veterinarian recommended the emergency veterinarian provide fluid therapy, give the dog atropine (0.1 - 0.2 milligrams per kilogram (mg/kg). Give 1/4 of the initial dose intravenous (IV) and the rest intramuscular (IM) or subcutaneously (SQ). The dose can be repeated as needed, but do not over-atropinize the animal. The primary goal of atropine use is to control bradycardia and bronchial secretions.), manage tremors (methocarbamol 50-150 mg/kg IV; Diazepam 0.5-1 mg/kg IV), and to provide oxygen (provide oxygen and ventilatory support as needed for animals in respiratory distress).

19. Provide supplemental information here

The APSS veterinarian stated that the substance was considered to have a high likelihood of causing the clinical situation. On January 10, 2019, an APSS assistant called to follow up on the case. The emergency veterinary staff stated that on January 8, 2019, the dog was given symptomatic care (fluids, Cerenia/maropitant, methocarbamol, Valium/diazepam, and acepromazine (Ace)) oxygen and activated charcoal. The emergency veterinary staff also stated that on January 9, 2019, the dog's signs resolved and that the dog was released later that afternoon. APSS Case 190004571
