Why would you give bay leaves to dogs?
Bay leaves are aromatic leaves of the bay plant, often used in cooking soups and stews; they are also featured in recipes such as pot roasts and other hearty meat dishes. Bay leaves are not toxic to humans, but they often have a bitter, intense taste that makes removal of them from the stew after cooking a habit of many cooks.
Bay leaves will likely have the same effects on dogs - not toxic (probably), but also not palatable. There is no medical reason to give bay leaves to a dog - they are flavorful, but they are not medicinal or healing. However, I suspect someone somewhere on the internet may have posted information stating bay leaves are good for dogs. There is no scientific evidence suggesting that bay leaves are anything but an aromatic herb useful for flavoring human foods.
If you mean baby oil, then any drug store or supermarket would carry it. Bay oil, also known as Oil of Bay, is an essential oil extracted from leaves of the bay tree, or bay laurel. It is used in aromatherapy and is also sold for medicinal purposes. A pharmacy or supermarket would be a likely place to buy it, Although bay leaves, from the same tree, are widely used in cooking, I've never heard…
Bay leaves grow on a tree and can be used in cooking - they are safe to eat = Answer = Bay Leaves come from the sweet bay or laurel tree, known botanically as Laurus nobilis. They are often used as a flavoring for soups and stews, but the leaves themselves are bitter and hard to chew, so are generally discarded after cooking.
Cassia leaves are erroneously referred to as 'Indian bay leaves', even though they belong to a totally different botanical family and look nothing like a bay leaf. Cassia leaves can be twice the size (both in width and length) of the European bay leaf and when dried turn a dull brown colour and are inclined to break whereas bay leaves, tough and leathery as they are, are more likely to survive the drying process intact.
