Remove a common word from each string value in an array

I am populating an array dynamically which is based on all the ids on the page's video tags.

How can I remove the word dog from each array item's value? Here is the populated array so far, I just need to remove the word dog for each array item:

var players = new Array();
$("video").each(function(){ 
    players.push($(this).attr('id'));
});

So it would go from:

["video_12_dog", "video_13_dog"]

to:

["video_12", "video_13"]

You could iterate over the array and call replace() on each element (as string):

function removeWord(arr, word) {
    for (var i = 0; i < arr.length; i++){
        arr[i] = arr[i].replace(word,'');
    }
}
var aaa = ['value_1_dog', 'value_dog_2', 'dog_value3'];
removeWord(aaa, 'dog');
console.log(aaa); // ["value_1_", "value__2", "_value3"]

var question = ["video_12_dog","video_13_dog"]
removeWord(question, '_dog');
console.log(question); // ["video_12","video_13"]
