Dogs can eat raw hamburger meat but you should really boil the hamburger meat for a minute or two to kill off bacteria such as Salmonella.
But if you want to you can feed the dog the raw hamburger meat as is without boiling it first but it's recommended to boil the raw hamburger meat and any other meat for a few minutes before giving it to the dog.
If your dog has kidney problems or liver problems or cancer then you should not feed the dog raw hamburger or any raw meat because it can make their condition worse.
But for healthy dogs raw hamburger meat is just fine for them.
