Get the dog on dead birds asap.Smaller birds if possible,or wings. Socilization is very important at this young age. Bring the dog every where you can. Try to get her around as many new people as you can. Take your time.
There should be a small hole up by the coupler that you can put a pin in that will keep the trailer from sliding forward making the breaks lock up while you are backing up. I had the same problem with my 2004 Warrior. It ended up being a short in the plug, Warrior had it fixed same day for me….great service…..Good Luck!
I had the same problem with X-27 in shallow water. Had to have it reprogramed because it didn’t have a shallow water mode. Sine then it has been working fine.
