I have an 11 week old toy-small size breed, he is really a joy and training is going normal except the separation barking/whining. When I'm gone I have been informed my little dog just barks and whines for what could be hours (I not sure because it happens when I'm not here). When I am I practice the your barking/whining so you get no attention thing like walking away or ignoring, it works, he stops when I get home and while I'm home but while he is alone (which is rarely more then 3-4 hours) I guess he is just a noisy guy. How can I make this stop, he behavior is fine while I'm home and the ignoring trick works when I'm here but don't know what to do about while I'm gone and how to teach him that.
