I agree with Alin. And I would really cancel this appointment if you want to have a healthy dog. I had German Shepherd which I neutered in his 8 year. He was stubborn as character and dog reactive. Neutering did nothing to his behaviour, but only made it worse. He became some people reactive, he started eating my parquet floor and my books, he became obsessed with food, he started guarding the sofa. I did it because the vet recommended that after age of 8 it would be good for his health and prostate.
I will never ever neuter a dog if there is no serious medical problem and it is really necessary because of health reasons.
The behaviour you see now and describe is his teenage hormones. My Malinois boy was such a pain in the ass at his teenage time, but he is the best dog ever now. I worked, I trained, I read, watch and consult with trainers. It took few months but it was so much worth it. Best thing I did – I learnt how to play with him and how to bond.
You should be consistent and have patience and work with him more, work on focus and obedience. And not only work – but make the play time the most important time of the day. Teach him to play with you and be the most exiting and interesting thing for him. Play as partners and do not show competition or conflict in the game. Work on your bond. Sit and lay with him on the ground/floor, spend time together.
I also want to share this video by Dr. Karen Becker, please watch it and please cancel the appointment.
