Behavioral issues/training

Hi everyone, I’m thinking of getting a Pomeranian (hopefully black and tan) sometime in the future and I was wondering if they have any major behavioral issues that can be trained out of them and how you managed to do it, e.g. barking, biting….

I have no experience with this specific breed although I know that they are essentially miniature spitz and I’ve pet sitted a large spitz before. I have previously had a cavalier King Charles spaniel and now an Australian shepherd, so I’ve experienced two sides of the spectrum when it comes to maintenance levels lol.

But yeah, was wondering if there’s any common behavioral attributes that you have successfully trained out or when training should start with such a breed, thanks!
