    formater.setTimeZone(TimeZone.getTimeZone("Europe/Madrid"));

    Calendar cal = Calendar.getInstance();

    try {
        cal.setTimeInMillis(formater.parse(strDate).getTime());
        String offerDate = cal.get(Calendar.DAY_OF_MONTH) + "-" + cal.get(Calendar.MONTH) + "-" + cal.get(Calendar.YEAR);
        System.out.println(offerDate);

tl;dr

java.time.Instant                    // Represent a moment as seen in UTC.
.parse( 
    "2014-01-10T09:41:16.000+0000"
    .replace( "+0000" , "Z" )        // Strict compliance with ISO 8601. 
)

java.time

You are using terribly-flawed legacy classes that have been supplanted by the modern java.time classes defined in JSR 310.

Instant

The Instant class represents a moment, a point on the timeline, as seen from an offset from UTC of zero hours-minutes-seconds.

ISO 8601

Your string nearly complies with the strict version of ISO 8601 standard. The standard tolerates an offset missing its COLON character, +0000 rather than +00:00. But the Instant class does not by default. So replace that part of the string. You can use Z as an abbreviation of +00:00, pronounced “Zulu”.

String input = "2014-01-10T09:41:16.000+0000".replace( "+0000" , "Z" ) ;
Instant instant = Instant.parse( input ) ;

I think the easiest would be to use another formatter object to do the formatting instead of building it yourself:

try {
    Date d = new Date(cal.setTimeInMillis(formater.parse(strDate).getTime()));
    SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");
    String offerDate = format.format(d);
    System.out.println(offerDate);
} catch (Exception e){
    System.out.println(e.getMessage());
}

The documentation states:

java.util.Calendar.MONTH

MONTH public static final int MONTH Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.

-> Counting starts at 0 for Calendar.MONTH
