I have a lead on a standard yorkie puppy that is 5 months old and weighs 4 to 5 pounds. Does that sound like what one should weigh? Her owner told me that she is also not potty trained and I know that it can be difficult to train a yorkie in the first place. What is your opinions on that? This will be my first yorkie and I want to get a good one, so if anyone has some advice on what to look for please let me know. I would also like to know what everyone uses to bathe, feed, etc. their yorkies. I greatly appreciate everyone's help! Thanks! Joanna
