Javascript regex capture next word

I am searching a regex to find next word after "dog" for example, and delete it

"123 dog rabbit cat".replace(myregex, "");
"123 dog cat"

Thanks

edit: but 

"123 dog <b> ok</b> cat".replace(myregex, "");

should not do anything

Expressions posted so far will fail on e.g. 123 dog <more spaces> rabbit cat, so I think the \s+\S+ or \s+\w+ would be more accurate:

console.log("123 dog     rabbit! cat".replace(/(dog)\s+\S+/, '$1'))  // 123 dog cat
console.log("123 dog     rabbit! cat".replace(/(dog)\s+\w+/, '$1'))  // 123 dog! cat

I added ! to your string to show the difference between \S and \w.

You could use:

"123 dog rabbit cat".replace(/dog (.*?)( |$)/, "dog ");

Simplest way to do that:

"123 dog rabbit cat".replace(/(dog) \w+/, '$1')
