Chop or break up the beef into small pieces so they are bite size for your dog.

Place a large nonstick skillet over medium heat and add the water.

Add the beef to the skillet and cook, stirring frequently and breaking it into small crumbles, until fully browned and no pink remains, about 10 to 12 minutes.

Skim off and discard any visible fat that collects on the surface or in the pan.

Add the carrots and peas to the skillet and stir to combine with the beef.

Cook, stirring occasionally, until the carrots are tender and the peas are heated through, about 8 to 10 minutes, adding a splash of water if the pan looks dry.

Reduce the heat to low and stir in the cooked brown rice, breaking up any clumps so it mixes evenly with the beef and vegetables.

Sprinkle in the dried parsley, if using, and stir until everything is well combined and warmed through, 3 to 5 minutes.

Remove the skillet from the heat and let the mixture cool to room temperature before serving to your dog.

Divide into 4 portions and refrigerate or freeze unused portions promptly.
