You need to set up your own Client with your own Transport which uses a custom Dial function which wraps around DialTimeout.

Something like (completely untested) this:

var timeout = time.Duration(2 * time.Second)

func dialTimeout(network, addr string) (net.Conn, error) {
    return net.DialTimeout(network, addr, timeout)
}

func main() {
    transport := http.Transport{
        Dial: dialTimeout,
    }

    client := http.Client{
        Transport: &transport,
    }

    resp, err := client.Get("http://some.url")
}
