Accordingly, can Border Collies be left alone outside?
Border collies should not be left alone for long periods of time. Your collie should have someone visit them if you're gone for more than 3 or 4 hours. Border collies can develop separation anxiety and isolation distress easily.
Beside above, how do you keep a border collie in your yard? To solve it, you can buy mental stimulation dog toys that he can play with in your yard. If that doesn't work, throw some tasty chewable treats. That will undoubtedly distract his mind from digging to chewing.
Then, can you train a border collie to stay in the yard?
Training your dog to stay in an unfenced yard is basic boundary training. This might be a difficult task at first, but remember to repeat this training each day, several times a day, in short sessions to get your dog to understand and remember the rules around the border.
Do Border Collies wander off?
As with any dog, Border Collies don't run away from a place they consider their home sweet home — unless of course, things went sour and they finally have a good reason to leave. A dog roaming around is different from a dog running off and never returning.
