I posted last week that I was away for 2 weeks visiting my son and daughter in law - leaving Mr. Darcy and Miss Lizzie at home with my husband. He email on the weekend that Lizzie is pooping in the house.....She always 'yips' when I am there to be let out. I don't know if it is because he is out later in the evening (he is home in the morning) or because she misses me. It is a damper on my vacation, because I just want to hold her. Darcy seems OK, but I want to hold him too!!! I am so enjoying being with my son, as I only see him a couple of times a year, but I almost feel sick thinking about how Lizzie 'thinking' - she must be wondering where I am. My husband and daughter are picking me up from the airport (2 hours from where we live) and I told them not to come if they aren't bringing my puppies with them! I have heard dogs don't have a 'time concept' - any one know if this is true?????
