I read everything I can about my wonderful pup and am a little concerned about leaving her. All the Havanese books and articles say they don't do well left alone for long periods of time. "Allison" is 6 months old and has been going to work with me since the day I brought her home. She is very well behaved and loves everyone. We have left her when we go out in the evening for 3 - 4 hours, and she does very well. Although she is in a large pen, I have 3 other dogs to keep her company. My question is, how long is too long to leave her ? Although my boss has been great, I know he would like me to start leaving her home. I don't want her to have seperation anxiety, but she seems to be very well adjusted. Am I a nervous new Mom ?? Any help woiuld be greatly appreciated !!
