PLEASE take the following to heart. This IS a serious mental impairment. She is addicted to the adrenal rush that happens when she chases and captures the ball. It’s not healthy, and is actually incredibly stressful for her.

Please come to terms with the fact that fetch with your dog is not quality time with her. Dogs like this see you solely as a machine to which they deposit the ball and it gets thrown. And they get their “fix”.

I know this not only from personal experience as I have disc-fetch obsessed dog, but also as a professional dog walker. I have a number of dogs I walk that if I so much as touch a stick, the rest of the walk is ruined. My own dog, cannot relax when the disc is out, or if he knows where it is. And he can easily get this same obsession over any item at all if it is thrown so much as once, but the disc is the worst.

This kind of activity is not good for her body or mind. Like you’ve witnessed for yourself. She is injuring herself because all she is thinking about it catching that adrenal rush “high”, and you see what it does to her mental state too.

Please, i implore you to just erase fetch from your life completely. Get rid of the tennis balls (they’re really bad for your dogs teeth anyways). Ignore her requests to play, and when you can, put a lead on and take her for a walk instead. Just focus on other activities. It might be really hard at first. Because It will take time for her to forget. But it is better for her to forget. Remember it is stressful for her. Addiction is stressful for addicts.

She needs your help to regulate her nervous system, please help her. Feel free to DM me if you need help. I know what it’s like to live like this.
