I recommend the Dogtra 3500NCP series of collars for people who have large / giant breeds or very stubborn / high drive breeds that they find extremely difficult to control. That is not to say that this is purely a high power collar. It can be as mild as a Dogtra IQ but has more stimulation at its top end for higher drive or stubborn breeds.
Also for those needing transmission poower. The transmitter will work out to 1 mile but will punch through obstacles better when faced with forrestry, hills and dales.
