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 recently purchased your collars and I have to say, I'm really impressed with the quality and design. However, I've encountered an issue with one of the collars as it has developed a tear, and the quick-release plastic slide buckle has broken. I use the collars strictly for outside walks, and I always ensure my dogs are never left unattended outdoors. I'm reaching out to see if there's a way you can assist me with this problem. I'd appreciate any support or solutions you might have to resolve this issue, as I'm keen to continue using your products with my dogs. Thanks for your attention to this matter!
