Hello. I've just joined. We're lucky to live in a very rural position where we've kept dogs & other animals for over 30 years but would still welcome any advise. Monty, our kelpie x border collie had epilepsy for the last 8 of his 11 years. With failing sight & hearing, we had him put down 2 months ago. Very hard. We collect our border collie pup in 3 weeks. Previously, with training, we've not had a significant problem with our dogs wandering but, even here, traffic is increasing. Conventional fencing would be a major problem so we're considering an electronic fence. Any experiences? I tried searching "electronic fence" here but found nothing.
