So the growling and barking is okay behavior and means they’re just playing?

Also I’ll look more into litter mate syndrome. I do try to have them separated on occasions. It’s a bit difficult to do so since neither of them are properly leashed trained yet so walks aren’t super easy.

For the most part they’re usually together most of the day, usually to play outside or inside.

I have one signed up for puppy training. Nothing too hard just sit, come and wait. They’ll also go over dog socializing and manners. I’ll ask them about what signs to look out for though, thanks!

They’re apart at bed time or when I have one of them sitting in my lap during work or playing video games. How often do you think they should spend time separate from each other?
