If I could change one thing about the Affenpinscher, it would be their independent spirit. While this trait makes them unique, it often leads to stubbornness that can complicate training. They can be a bit willful and may decide to ignore commands if they are not in the mood. It's charming but can be quite a challenge. Ultimately, a little more eagerness to please would be a great addition.

I would change their stubbornness. It can make training a bit tricky.

I’d love to see them be a bit less prone to anxiety. Affenpinschers can get pretty anxious in new situations, which can lead to excessive barking. I’ve had to work hard to desensitize my pup to different environments. A little more calmness would definitely help them enjoy outings without stress.
