Madness at 10 months

Back here again, I just need some positive stories from people. My dog, 10 month old male Keeshond not neutered.

I love him so much but am having a hard time. Main problems, madness after each walk and then madness in the evening.

Can anyone give me some positive stories of their dog being mad and then being better at 1 year and then even better at 18 months?

I ignore the nipping, barking etc but some days it’s just so exhausting and I need some hope. I have done capturing calmness, relaxation protocol etc – hasn’t made a difference for us.

Thank you in advance, I just need some hope.
