Hey Sue,
Bad luck, it is so upsetting when all your hard work is binned by the little darlings for a few minutes of reckless fun
I really feel for you as it's soo frustrating when things like this happen and people who see your dog behaving naughtily immediately think that you haven't bothered with training etc...
I'd recommend that you have a nice chillaxing time this evening with your soft little girl on the sofa with a glass of wine, and just have a nice huggy time with the norty little devil
I'm sure you're feeling upset at the fact that you feel like you want to kill her at the moment but also need a little furry hug too!
My advice would be to take quite a tough approach with Chloe as she's clearly learned that sheep are fun to chase and you need to teach her that sheep are not fun, in fact they're unfriendly, and should be avoided
. So my advice would be to find a sheep farmer who has a couple of rams in a medium sized pen and ask if you can put Chloe in the pen with the tups for a short time (most farmers know the score and will help you out in this way, they'll also help get Chloe out of the pen once she has been told off a few times by the tups). This method really does work wonders with instilling a deep respect for sheep into a dog that's prone to chasing sheep in the field, because the tups won't run away when the dog approaches, instead they stamp their feet, snort loudly, and rush towards the dog to get it to back off.
Then after a session with the tups if you walk your dog through a field of sheep and it takes no notice of the sheep (and might even hug close to your leg) give praise and treats etc... to reward her for her good behaviour of ignoring and avoiding the sheep
This is how my two have been trained, and all it takes is one or two visits to the pen of tups (the dogs don't get hurt, they know what's best for them and soon learn to run over to you to be lifted out of the pen
) for the dog to understand that there is no fun to be had with sheep. I really needed my dogs to be bombproof around livestock because on shoots fields that are being worked by your dog often have sheep in and so it would be impossible to go beating with my two if they were sheep chasers.
Good luck with Chloe
Best wishes,
Mary xxxx
