[SIZE]: Medium, 16 inch spiral stake, recommended for all breeds up to 100 lbs. [HEAVY DUTY MATERIAL]: Made of solid steel, the spiral design is specially used for sandy soil or loose ground and is firmly screwed into the ground for worry-free installation. [EASY TO USE]: Easy to screw the dog stake into the ground like a bottle opener, and then connect the collar to the tie-out cable, the clip can ensure an easy on/off the connection, saving time and effort. [REDUCE IMPACT DAMAGE]: Dogs have a lively nature, strong impact, and are full of curiosity about everything. They often chase cats, squirrels, sand cranes, and other small animals outdoors, which is likely to break the rope and cause neck damage. [Gift for Animal Lovers]: It creates a safe area that allows your dogs to come and go freely while preventing them from being distracted and escaping from the yard. This is a good gift for dog lovers.
