Abalone

Abalone is not toxic to dogs. The trouble is that dogs almost never encounter plain abalone — they encounter sashimi, abalone porridge, butter-garlic abalone, or soy-marinated jeonbok-jang, and the risk lives in the preparation. Start with raw. AKC's shellfish guidance is direct: raw, uncooked shellfish contain harmful pathogens, and cooking eliminates them. On top of the bacteria, the Merck Veterinary Manual notes that thiaminases found in raw fish and clams rapidly destroy dietary thiamine and can produce a deficiency; cooking destroys the enzyme. Raw abalone sashimi is not dog food. The shell and the viscera come next. Abalone shell is hard, and it breaks into edges sharp enough to cut a mouth or lodge in the gut. AKC makes the same point about shrimp shells: they are a choking hazard and can cause obstructions, especially in small breeds. The dark viscera — the digestive gland — is full of whatever seaweed the animal had been eating, spoils quickly, and gives your dog nothing. Trim it off and use the white muscle only. Then the cooking. Abalone porridge is built on rice toasted in sesame oil and salted to taste, often with the viscera blended in. Butter-garlic abalone is exactly what its name says. Jeonbok-jang sits in soy sauce for days and should be treated as a block of sodium. Merck puts the clinical threshold for raw onion at 15-30 g/kg with garlic 3-5 times more toxic, and salt toxicosis signs at 2-3 g/kg with a lethal dose near 4 g/kg. Texture is the last piece. Cooked abalone is famously rubbery, and a dog who swallows a chunk whole has swallowed it whole. AKC's portion guidance for shrimp — one or two pieces for most dogs, a partial piece for a small dog — is the right scale here, chopped small. Vomiting, diarrhea, abdominal pain or lethargy within a few hours usually points to bacteria or seasoning. Repeated vomiting, a painful belly, no stool and persistent unproductive retching point instead to obstruction, and Merck is explicit that GI obstruction is an emergency. Either way, call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 rather than inducing vomiting at home. The short version: plain, thoroughly cooked, shelled, gutted, finely chopped, occasionally, and inside the rule that treats stay under 10% of daily calories.
