> there are not enough years in my life where I can have one dog at a time
Totally understand your argument. :-)
I realise that pet dog owners say that they couldn't cope with my houseful, but it works for me. I love it when visitors are impressed with them! I recently had a lady vist with 2 daughters, wanting to mate their little Yorkie girl. After explaining all the problems that can crop up, they have changed their minds, but I think they made the right decision for a much loved pet. One of the daughters ( in her 20's) said - I can understand why you have every one of them. I was so, so chuffed with the gang.
All living indoors makes it easy to study dog behaviour, and their interaction with each other. I don't think they're human, but I would probably say that they are sometimes a lot nicer than humans!
So, as far as hubby goes - move slowly but surely. And mine's a large one! :-) :-)
