Hi there Just after a rough price tbh. I’m currently recovering from a heel surgery where I am non weight bearing for 6 to 12 weeks. I’m also not driving as whilst my left foot so I am allowed in an auto or EV it can be a big bloc of plastic-cast that I think stupid to risk. Thursdays are a difficult day for my other half, as I’m in hospital in Guy’s in London, and she plays sax, and practice knackers her to start with let alone walking Casper. About him: He is great at recall, when HE wants to. He loves bigger dogs (clearly smaller than him as he’s the size of a horse) in his mind. We therefore had him trained to use a mini-educator TENS machine. In theory a press of one button, should beep and he should return. If over excited e,g. A cow, horse, deer, squirrel etc, the press of a different button will activate the TENS which is a buzz (not an electric shock) that should interrupt his thoughts so he should comply. If you’ve not used before,we can show you. When we first engaged the trainer and he asked are you familiar with TENS, I replied “a Transcutaneous Electrical Nerve Stimulant” and he was gob-smacked. I added I’ve used one on my back for years to alleviate back pain. I hope this helps clarify things? Who knows, if things work for you and him, perhaps we might add a Monday, when I’m in St Thomas’ again in London. Thanks Richard
