Effective Use of Shock Collars for Barking Control

For those who have used shock collars to manage excessive barking, what has been your experience in terms of effectiveness and safety? Are there specific settings or practices you would recommend ensuring humane and consistent training results?

Hey dog breeders.
while shock collars can be helpful, they should only be used as a last resort and with the supervision of a professional.
Prioritize positive reinforcement and compassionate training techniques to ensure your dog’s pleasure and well-being.

I use shock collars to return my dog to me. Every time when we take a stroll in the evening and she sees a cat or other dogs, she gets so aggressive and wants to chase after them. That’s the only time I use electric shock collars. I’d be pleased to learn how they are used to control barking.
