Ive trained hunting dogs for 40 years. Mostly GPS..Brits....the last few years ive taken on one chocolate lab name Maggie....started with her at 15 weeks...basic OB trainning..sit stay come..a lot postivity....no hollering....I let the dog tell me when it was over and always took a goody bumper with me......and I did this for a good few months...when she knew all the commands...that's when I collar trained her only to enforce what she already knew.,so a collar is just a tool that we use to enforce...not for bad behavior..a lot of good dogs have been ruined by miss use of them..so do you basic OB trainning have fun doing it and don't take you frustrations out on you young dog.....end the trainning on a good note...Ive had my sportdog 800 for 6 years in and out of water and its never let me down....goodluck.
