Bubble and squeak is a traditional English dish made from leftover vegetables, typically potatoes and cabbage or Brussels sprouts. It is usually fried in a pan until crispy and served as a side dish. While dogs can consume some vegetables, it is not recommended to feed them bubble and squeak as it contains onions and garlic, which are toxic to dogs. Additionally, the frying process can make the dish high in fat and salt, which can cause digestive issues and obesity in dogs.
In extreme cases where a dog has consumed bubble and squeak, it is important to monitor them for symptoms of onion and garlic toxicity, such as vomiting, diarrhea, and lethargy. If any of these symptoms occur, it is best to seek veterinary attention immediately. Two safer alternatives for dogs are boiled or steamed vegetables, such as carrots, green beans, and peas, and plain, cooked potatoes without any added seasonings or oils.
