O.K. . . . the time has come where Ash is going to have to be crated while I'm at work. I have been fortunate enough to have my mom watch Ash while I'm at work the whole time I've had Ash. My mom has been an angel. Now though, my parents are having a built-in pool installed in the backyard and the construction means that Ash has no backyard to play in and to go potty in (although Ash is inside most of the time) and the noise is driving Ash nuts. She is jumping at the windows, growling at the work men, running back and forth and it's driving my mom crazy. On top of this, my mom has just taken in her nephew for the next few months and having the 5 year old boy and my very hyper dog is too much for my mom right now. So, into the crate Ash will go.
I live in a apartment and Ash has no problems going into her crate. She never resists and goes in willingly. The longest she has been left in has been for about 5 hours. Lately, she's been going in more and she's started to bark when I leave the house. This wasn't happening for awhile, but it's come back. She barks and I CANNOT have her doing this. I usually leave her with a huge kong filled with treats and foods and I leave the tv on. When I come home from where I was, I creep up to the apartment to listen and see if she's barking and she never is.
The times I've left her have been to go grocery shopping or to the movies. Sometimes when I have to work overtime on a Saturday, she stays in the crate. Once again, it's gotten much more frequent recently and she's started the barking.
The last time I left her in there, I came back and she had completely chewed up the crate bedding. She has never done that before. I had gotten called in to work last minute and absolutely had to leave ASAP and Ash hadn't had more than a 30 minute walk so I'm pretty sure it was because she hadn't been exercised long enough
I leave the house at 8:30 am and get home by 6:30 

m. My mom or brother will most likely come by to let her go to the bathroom (which is another concern). What can I do before I leave for work to absolutely exhaust her? I will wake up as early as I need to in order to make sure she is beyond tired? What should I be leaving her with in the kong? I don't want to put something in there that is gonna make her super thirsty or have to go potty right away.
Just in case anyone is wondering, Ash is a 16 month, female, Australian Cattle Dog. I won't be able to afford hiring a pet sitter/dog walker, so she'll be in her crate almost the entire time I'm at work. This is why I want to give her as much exercise before I leave and when I get home. Do you think exercise will stop her barking? Any other suggestions on getting her to stop barking?
