I am an obedience instructor and have a very large Cane Corso in my class. I'm unsure of what type of training collar to use.

I am an obedience instructor for my training club and I have a question about training collars for large breed, protective dogs. I currently have a 120 lb Cane Corso in my class and I'm unsure what type training collar I should use. The dog seems very mellow, but it was only the first class. I have experience with prongs and use them quite often with success. Since this breed of dog is known for aggression and because of the size and power, I really need help. Currently, the owner is using a plastic type prong, I think they're called "gentle" prongs. I'm thinking this might not get the job done.

Thanks and I really appreciate this website and your wonderful products!

Thanks, Cindy. I've never worked with dogs that are this protective before and I didn't want to use a collar that was inappropriate. I think I'm going to direct them to your website to get a Herm Sprenger prong because I don't think this plastic and parachord "prong" they are using will hold this 120 lb dog back.

Thanks again for your time
