Hi Maximo,
Thanks for your reply. What worries me more than anything really is the toilet situation. My seven month is not yet perfect. We cannot leave our doors open as we have a pool, so have to keep taking her outside. Sometimes we miss her signal, but on the whole she is very good about it and our floors are tiles. My other dogs are 1 rottweiller and one jack russell. My yorkies's pal is the jack russell and she is always with him, but she and the rottie get on well too. No problems at all.
