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

Sometime between August 12, 2018 and August 13, 2018, the dog ingested an unknown amount of this bait. In the afternoon on August 13, 2018, the dog was unresponsive and the owner took the dog to the regular veterinarian who gave a dose of epinephrine. The dog was recumbent and developed lethargy, dyspnea, and bradycardia. The regular veterinarian then contacted the Animal Product Safety Service (APSS). The regular veterinarian stated that the owner may have given the dog salt prior to coming to the clinic. 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. The APSS veterinarian continued by stating that if not a lethal exposure, signs are expected to resolve spontaneously due to the reversible nature of carbamate toxicity and that death may occur due to severe bronchial secretions or seizures. The APSS veterinarian also stated that sodium chloride (table salt) can lead to signs of vomiting, polydipsia, potentially hypernatremia, and central nervous system (CNS) signs. The APSS veterinarian further stated that salt toxicity results in ataxia, tremors, and possibly seizures, and if left untreated can cause cerebral edema and potentially death. A few minutes after starting the call, the dog developed vomiting (there was bait in the vomitus). The APSS veterinarian recommended the regular veterinarian give atropine to control muscarinic signs. 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. The APSS veterinarian also recommended the regular veterinarian manage vomiting, provide fluid therapy, monitor electrolytes for hypernatremia from the salt, monitor for gastrointestinal (GI) signs, monitor for respiratory signs, monitor cardiovascular function, give diazepam (or midazolam for tremors/seizures), give methocarbamol (for tremors), provide supportive care, provide symptomatic care, and to call back with questions.
