I have two poodles, a 13 year old toy and a 6 year old standard. Chelsea, the toy, goes to my friend's house while we are on vacation. Annie goes to the groomer's house and stays with her. These are people they are familiar with but I am still sad when I leave them and they cry when I leave. My DS (24) wanted to keep Chelsea with him but he works 12 hours a day and that is too long to leave her alone. She would be really sad.
