dog harnesses and leashes. These accessories are designed to help control a dog during walks and outdoor activities. 

Harnesses, which go around the dog's chest and back, can provide better control and help prevent neck and respiratory problems that might occur with a collar. 

The items appear to be made of durable materials like nylon webbing, potentially reinforced for strength, which is suitable for strong dogs. 

The set includes multiple harnesses and leashes in red and green colors.

The leashes allow for a secure connection between the owner and the dog.
