Gizzard

A gizzard is the muscular grinding stomach of a bird — dense, chewy, very lean, and high in protein. Simmered plain and sliced thin, it makes a long-lasting training treat that costs almost nothing. In the US, gizzards come either in the giblet bag inside a whole chicken or turkey, or in one-pound trays in the meat case. The most common accident here has nothing to do with toxicity. Gizzard resists chewing, so dogs tend to gulp large pieces, and a whole gizzard can lodge in the esophagus or gut of a small dog or a habitual gulper. Slice it thin or dice it. Never hand over a whole one. Skip raw. FDA testing of 196 commercial raw pet food samples found Salmonella in 15 and Listeria monocytogenes in 32, and dogs can shed those bacteria while appearing healthy. The versions that cause real trouble are the seasoned ones: Southern-style fried gizzards, gizzards simmered into giblet gravy with onion and celery, and anything dusted with garlic powder or seasoning salt. Per Merck, sulfur-containing oxidants in Allium species damage canine red blood cells and cause Heinz body hemolytic anemia, and most reported toxicoses involve concentrated forms such as dehydrated flakes, powders, and dry onion soup mix. The timing is the trap: methemoglobinemia begins within 24 hours and peaks around 72, while hemolysis usually appears 3-5 days after exposure, so a dog that looks fine the next morning is not in the clear. Fry oil adds its own problem, since dietary indiscretion is a common risk factor for acute pancreatitis in dogs. Keep treats under 10% of daily calories. If your dog ate seasoned or fried gizzards, note the amount and time and call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435, then watch the gums for paleness or yellowing and the urine for a red-brown color over the next several days. Do not induce vomiting at home.
