Hello! My mom is a dog trainer at www.1on1pet.com and this is what she says:
You have a very smart dog on your hands - Border Collies are one of the most intelligent dog breeds (which you probably already know) and with that great intelligence comes a great need for stimulation. If you find that your pup is chewing on anything she can find and just generally driving you a little crazy, she needs more stimulation. There are many different ways you can do that and feel free to get creative. Here are some examples: going out for a walk (several times a day), training (3 minute sessions several times a day), hiding treats around the house and having her find them, putting treats inside a puzzle toy like a Kong (she has to work to get them out), etc. When she does start chewing on something she isn't supposed to have, redirect her to an appropriate chew toy by "trading" and praising her for taking the chew toy instead of ruining your shoes. Good luck!
