Do NOT ever attach the leash to his collar! Even one incident of pulling or running fast to the end of the leash could cause serious neck damage, such as bruising, whiplash, headaches, crushed trachea, damage to larynx, and fractured vertebrae. A neck and spinal cord injury can cause paralysis or neurological problems. Use a secure, well-fitting harness instead.
