problem with WDT

Hi I´m working with the arduino mini pro (ATmega328) and I uploaded the following code:

#include <avr/wdt.h>
#include <Wire.h>
#include “MS5837.h”

MS5837 sensor;

void setup() {
wdt_disable();
Serial.begin(9600);
Wire.begin();
sensor.init();
sensor.setFluidDensity(997); // kg/m^3 (freshwater, 1029 for seawater)
wdt_enable(WDTO_60MS);//es el tiempo que va a durar el loop en ejecucion
}

void loop() {

for(int i=0; i<=1200; i++){
sensor.read();
Serial.print(sensor.pressure());
wdt_reset();//actualiza el watchdog para que no produzca un reinicio
delay(50);
}
delay(70);
}

But then I tried to upload another code and it didn’t work, because the arduino is resetting itself constantly.
its there a way that i can reset the arduino without using the programer because looks like it´s not going to work the way I´m trying.

Load up blink or some other sketch in the IDE. Hold the reset button down on the board, press and hold. Press upload in the IDE. Watch the output and right as it calls avrdude to start the upload you let your finger off the reset button. You might have to try it many many times to get the timing just right. But eventually it will load the new sketch.
