OK, so a lady (who shall remain nameless) told us about an incident with her dog and his IUC-5100 remote training and fence collar – the Innotek IUC-5225. (The IUC-5100 is a Contain ‘N’ Train combined remote trainer and fence product). The collar and remote are shown below:

She has a very powerful dog who gets out of the yard and can cause havoc. When she first got her Contain ‘N’ Train unit, she was using only the training collar since the fence wasn’t installed yet. So, she’d put the training collar on the dog and let him outside, always keeping the remote nearby.
She realized she hadn’t seen him in a while, so she started calling his name. He didn’t answer. She went running around to his normal spots in the yard. Not there. She thought he’d got out again, so she started the collar stimulation. Nothing. All the way up to nine. Nothing. Then she walked around the corner of the house to see him sat, looking a little dishevelled, right where he’d been the whole time. By the back door!
She said he’s been a different dog ever since, but please, please, all of you out there: don’t allow the panic to set in. Act quickly and decisively if you think he’s trying to escape, but make sure he really is!
