Hi again Weggo
I have to agree again with what others have said - another dog at this stage could be a disaster. Again, have just spotted your othet posts so now know how old your lab is and also that you have some concerns at the mo about her own health.
Your young lab is busy settling in and growing up herself - to bring an older one in could cause significant problems. Better to wait until your pup has matured a little more - say another year or so. Added to the fact that she looks to be showing signs of having some sort of hernia - getting another dog at the mo really should be the last thing on your mind.
You have a lot of work to do with your girl if she is to be a well behaved and happy dog. trying to train two is a nigthmare, and if you go for a rescue dog, s/he is likely to have very special training needs and may not take kindly to a new home with a lively pup in it - as well as four cats.
It's very tempting to want two dogs straightaway, I know I did - but I was persuaded by those that know to wait until my first was fully grown and well settled before getting a pup. I did and am so glad. You will have all your time and energy taken with your current pup. Bringing in another dog - poss with problems will undermine what you have already acheived and is far more likely to cause you regrets than happiness for all. Plus, make the most of your lab's puppyhood - it goes so quick - then get another and enjopy that too.
