Your dog has separation anxiety which is causing her to act in this manner when you are gone. If she is capable of breaking out of the crate, you need to get one that she can't get out of. As she is tipping this one over to push the bottom out, you may be better off with a plastic airline crate than with the wire crate.

This link has info about working with a dog who has separation anxiety. You may also want to speak to your vet about medications to calm her when you are away.

I am not minimalizing the destruction but it has always been my experience that dogs are the most destructive between 9 - 16 months. I agree get a better crate and explore separation. anxiety. Also a walk in the AM and sometimes a park visit is not much exercise or mental stimlation for either of the breeds. Border collies need to do some kind of work. Have you done obedience training? Have you considered doing agility?

A Border Collie is a working dog and is bred to work 10 to 12 hours of hard labor a day. Labs are also hunting dogs - not as hard of a worker on a daily basis but they need to be outside and stimulated on a regular basis. To keep your dog from being destructive, I suggest you walk your dog for a good 45 minutes in the AM, If you can ride a bike, jog, run or otherwise make the walk something more than a stroll, that would probably be best. A good 45 minute walk 3 times a day will help. Play time at the park is an awesome way to help relieve a dogs frustration with regard to being pent up. The more interaction you provide for your dog the better off life will be. Contact a fly ball organization or find a nearby place to take your dog swimming (some BC's dont like the water) you can find another neighbor with a dog yours can play with for a couple of hours a day would be even better. The more you cage your dog, the more destructive it might become. If you know you are going out - I suggest you take your dog for a nice long walk or play frisbee for an hour before you go out, this will help settle your dog. Good luck

Great dogs, those border collies but I don't know how anyone has time to meet their needs. I can't figure out why they are so popular given they need so much mental and physical stimulation. Hours per day.

In addition to the activities mentioned above, you might also look into herding (for fun). We'll be enrolling for that soon ourselves.

And as a temporary solution to the crating, I might try a vari-kennel, one of the airline kennels with the spring action door latch. This will also double as a vehicular transporter of course on the way to herding, obedience, flyball, agility, or the park. They're usually well under $100 and so versatile.

I think your dog has two issues... one is separation anxiety and the other is boredom.

Boredom is easy to fix. Separation anxiety takes more effort and its not over night fix.

I think if you do a web search for separation anxiety you will find tons of suggestions.
