The ASPCA lists bay laurel as toxic to dogs, for eugenol and other essential oils that irritate the digestive tract. A single leaf simmered in a stew is a low-risk exposure; the bigger practical worry is that a whole stiff leaf can obstruct or scratch the gut on its way through.

Why Bay Leaf needs caution
Bay leaves come from bay laurel (Laurus nobilis), which the ASPCA lists as toxic to dogs. The toxic principles are eugenol and other essential oils, which irritate the stomach and intestines. Separately, the leaf itself is a mechanical hazard: it stays stiff and sharp-edged even after cooking.
Ground bay versus a whole leaf
These are two different risks from the same plant. Ground or crushed bay carries the essential oils without the mechanical hazard, so a pinch in a recipe is a stomach-upset question only. A whole leaf reverses the picture: the oil dose is modest, but the leaf does not soften or break down in cooking, and its stiff edges are why vets ask about whole bay leaves at all.
Signs to watch for
Vomiting, diarrhea, drooling; with an obstruction, repeated vomiting, straining, appetite loss, and abdominal pain

Check the exact item or ingredient before assuming two similar exposures carry the same risk.
What to do next
Take the bay leaf out of food before serving anything to your dog, and if one was swallowed whole, watch for vomiting or straining over the next 48 hours and call your vet if either appears.

A closer look at bay leaf
Bay leaves come from bay laurel (Laurus nobilis), which the ASPCA lists as toxic to dogs. The toxic principles are eugenol and other essential oils, which irritate the stomach and intestines. Separately, the leaf itself is a mechanical hazard: it stays stiff and sharp-edged even after cooking. The details below use the specific facts for this exposure, rather than treating it like every other food question.
1. Start with the exact exposure
For a closely related comparison, read Battered Fish. The essential-oil dose in one cooked leaf is small, and most dogs that swallow a stew bay leaf get away with mild stomach upset at worst. A handful of leaves, or fresh leaves stripped off a bay plant, is a much larger oil dose. Size matters for the obstruction risk more than for the toxin.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Bean Dip. One leaf, from a medium or large dog with no symptoms, is usually reasonable to watch at home for a couple of days. Several leaves, any amount in a small dog, or signs of obstruction: repeated vomiting, straining, refusing food, or a painful belly. Chewing on a live bay laurel plant also warrants a call.
3. If the details are uncertain
Follow the first 10 minutes guide. Take the bay leaf out of food before serving anything to your dog, and if one was swallowed whole, watch for vomiting or straining over the next 48 hours and call your vet if either appears.

For a medium or large dog, watch rather than panic. Keep an eye out for repeated vomiting, straining, refusal of food, or a tender belly over the next two days, and call your vet if any of those show up or if your dog is small.
No. There is no benefit to add and the ASPCA lists the plant as toxic, so there is no reason to season a dog's food with it. Leave bay out of anything cooked for the dog.
