He is a 1yr old lab. he was pulling terribly on leash. i got him a head collar. it works great. i don’t use the head collar, he still pulls but not a bad as before. What other training methods can i use so he wont pull? to be honest im not too concerned with him walking at my side at the moment, just the pulling. unless of course the way to training is walking by my side so he wont pull. ALL advice welcome!
