Great leash

Love it!
Color: Black, Size: 30FT
This 30 foot leash is absolutely amazing and I would recommend it to any dog owner! The length is wonderful for allowing my dog to be controlled on a leash but have her own space so if she feels like she’s making her own independent choices and has stability to walk around in a controlled environment. It’s very comfortable to use. The weight is not super heavy. I would say it’s an ideal weight for it being a 30 foot leash. I use it every single day.

Total waste of money
I wouldnt give it one star but had to to leave a review. Just got these balls September 8, 2025. As of today we are on our third ball, September 13. My dog only used in field for fetch. He never layed down and chewed on it. The inside of the balls came apart. I pulled off felt to show where. The ball is otherwise intact. Never had this happen to any ball I ever bought. I researched and looked for good reviews even off Amazon because my dog is a border collie and loves to fetch. This is a huge waste of of money and bad for environment
