Update: The pumi boys are doing well.
They're getting leggy and I'll post some pics once I have some decent ones. They are growing quickly!
I've become very attached to them and I'm not ashamed to say I love them dearly; even when Boomer poops on the floor. Boomer likes to poop a great deal. He usually poops twice. Once in one place then immediately in another.
Boomer is still more clutzy, has trouble jumping on the couch, and doesn't mind pooping where ever. Tweeter has much better bowel control and will make a whine or a bark when he needs to go out. As to the issue of sibling syndrome, well, it's not an issue. They both hang on my every word and movement, and each will listen to me individually. They know their names and will listen to me when I lead.
Everything has been much easier since I stopped worrying and learned to just roll with the punches. They're a blast to have around and we're having a good time. About the only trouble I have is getting them to realize the whole house is their den, not just their pen and crate areas. It will take a while but that's ok. As I'm remodeling, the carpet doesn't matter so accidents aren't a problem.
All in all, we're having a great time and again, I'll post pictures ASAP!
Many thanks!
