美国采购需求：狗狗训练项圈、无线狗围栏、防吠项圈、GPS追踪器、驱狗器、防吠项圈

I've been using your collars for a while now, but I've had issues with them breaking at the same spot—I've gone through six of them! I noticed you released an upgraded version with a shock feature for the Invisible Fence, which sounds great. I appreciate that you take customer feedback seriously. I'm really interested in trying the new collar, but I'm currently short on funds. I'll send over some photos of the broken collars and my pets wearing them so you can see what I've dealt with. Thanks for considering my situation!
