I don't have any magic words to give you only the encouragement to hang in there!!! I understand what you are going through. It IS very overwhelming when you have alot of responsabilites. Staying at home isn't lounging on the couch and watching tv all day long---especially with children-including your dog! Good luck and I admire your willingness to try and keep a family member with you at all costs
Regardless of what is offered to you as advice do what YOU feel works, is easiest and please give it time!!! I am still in the training mode with Lola so there is a long way to go with her but I don't give up! She's my first dog ever. Good luck
