Missy is like Holly she hates it when I'm gone for just a few hours.
I wouldn't be so worried about leaving Miss if it were with my mom. Since I'm going on vacation with my mom, dad, and 3 brothers she has to stay with a friend or other family. From previous trips Missy somehow seems to know that we're leaving because on the day when I start packing Missy sticks to me like glue and is really depressed.
I'm going to pack Missy's blanket, tug toy, tennis ball, stuffed teddy bear. I'm thinking of giving her something that smells like me, maybe it'll help. Most likely Missy will stay in her crate and only come out when someone begs her to go out to potty. She usually just sulks. My mom was trying to be able to bring her with us, but we can afford the fee to bring her.
My first choice is for Missy to stay with my friend's mom who has 1 Boxer and 1 Shih tzu. She is great with dogs and I know she will try and get Missy happy. Downside more than likely no walks because she will run into other dogs and the neighbors will not tolerate a dog acting like Missy. Her exercise will be fetch and tug if she will play.
Second choice my Nana. She has 1 Mini Chihuahua(Buddy who Missy adores) and Shadow Jack Russel/Chihuahua mix. My Nana loves Missy, but does not want to take her because Missy is Crazy. Someone at my nana's might play with her.
I remember the first time I ever left Missy for more than 2 days I cried when my sister drove away with her. I was about 14-15 so Missy was 3 or 4. I was so worried she would think we abandoned her like her old owners.
