Ever since I got our chihuahua when she was two months old..she doesn't bark like other normal dogs would usually do if there are strangers. She is turning one today and I only heard her bark once or twice. I actually like it that she doesn't bark but I'm just worried that if a stranger comes and take her or something she wouldn't even bark and give us a warning.She is so sweet to everyone that comes to our apartment. Have you encountered dogs who don't bark? Please let me know what you think.Thanks!
