i have 2 fully trained rotties 125+ lbs n they have their chokers on 24/7. it depends on the breed mine r great and friendly and i have had rotties for the last 16 years of my life but i still wouldnt trust them without one...
pinch collars for training choke collars for just whatever, but never use the choke just put it on the dead ring. using the choke collars damage your dogs 100000x more than pinch if your actually choking/strangling your dog due to lack of oxygen. pinch collars dont hurt your dogs, just get their attention.
