I'm working with Willow on a sit/stay at the moment. She's doing very well, but sometimes she starts jumping up when I click. I've obviously already marked the good behaviour so she gets her treat, so I'm not sure how to discourage the behaviour. At other times, she sits beautifully through repeated click & treats for an extended sit. Is it just a case of early days, or is there any advice to stop her doing this? Outside of sit training, I'm trying to discourage jumping up by rewarding her when her feet are on the ground. On another note, do you carry your clicker with you at all times when you're with your pup to mark any good behaviour, or use it only when you're specifically seeking that behaviour (ie in training sessions)?
