This issue came up in a thread about barking, but since it was off-topic and I wanted more advice, I'm starting a new thread...
My dog seems to have an obssesion with sticks... she picks them up whenever we're outside playing or walking. Sometimes she'll just play with a stick, but a lot of times she'll chew it up and swallow pieces. And although it's sticks that interest her most, she's been known to pick up-- and swallow-- pretty much anything that catches her attention. We taught her both "leave it" and "drop it", and this seemed to work well for a while, but now she seems to have relapsed. We had started to wean her off the rewards for these two commands, then she stopped listening, so we went back to consistant rewarding, and NOW the problem is that she's figured out "Hey, I can get a treat by picking up this stick and spitting it out when I'm told"... so I think she puts stuff in her mouth now more than ever!! I'll toss away whatever she's put in her mouth once she's dropped it (if I catch it before she swoops it up again!), but she'll just pick something else up. Also, she's recently started spitting out only PART of whatever she picked up, and continuing to munch on, and sometimes swallow, the rest.
When we're walking it's a little easier to manage because I walk her on a gentle leader which makes it easy for me to keep her head up, and if I walk fast enough she doesn't have much time to find things, anyway. It's more of an issue in the back yard, because the cemetary in back of us has a row of trees lining the fence, and it seems that sticks, leaves, and acorns fall from them constantly, and there's nowhere to go to remove her from the distraction except back inside.
So, I guess I'm partially looking for ways to get leave-it and drop-it to work reliably again, although I guess what I'm really looking for is some way to get her to lose all interest in eating foreign objects, because of course I worry about what she might be eating every time I'm not looking. Any advice??
