Final answer:
The function call for a function named 'dog' with no parameters is written as 'dog()'. This notation is used across many programming languages to indicate a function invocation.
Step-by-step explanation:
The function call for a function named dog that has no parameters is dog(). In many programming languages, functions are invoked or called by writing the function name followed by a set of parentheses. Even if the function does not require any parameters, the parentheses are still included to indicate that it is a function call. For example, in a language like Python or JavaScript, you would simply write dog() to call the function named dog.
