Many thanks to you all for your interest and advice.  I still haven't been able to move forward and make a definite decision.  What's wrong with me - at my age!  I'm researching some  rescue web sites and looking at a
King Chatrles or Cavalier, if I decide on a puppy.  I'll keep you posted.

Hi,  I'm new to the forum.  Another multi-cat household looking for a new canine addition.  I've read through the other posts, but please bear with me.  You may have some advice and guidance especially for me in my circumstances.  I'm 62 years old and retired.  I grew up with dogs but never had one throughout my working life, because of the high level of my committments.  I've always longed for a dog but, as stated, I have a settled feline household. (3 large males and 1 female - all adult rescue cats), so I feel I must proceed with some caution.  I tend to think I should aim for a 'medium-sized' dog.  I don't want a small one, but, as I am a tiny Scottish lady - 4ft 9",  weighing 5.5st, I don't want a dog bigger than myself!  I have a house and garden and exercise will not be a problem.
I have no preference for any particular breed, or for any breed as opposed to a non-breed,  I never imagined I would have a puppy, but wonder if this is the way forward in terms of expectatios of size and temperament etc..
Any help and advice would be welcome.  I feel my caution is becoming stalemate, and I do want to move forward and realise my dream.   Thank you so much.
