Thelma + Louise my Yorkie-Apso

The Yorkie-Apso is a cross between the Yorkshire Terrier and the Lhasa Apso.

The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in either breed.  Thelma is the watch-dog Terrier while Louise is the baby Lhasa Apso who loves to cuddle.  Both get confused when the weather changes dramatically and I am back into 'house-training mode'.

Here is where I can use YOUR help.  The only time they are NAUGHTY is when they are on the leash, see another dog, and they excite each other.....then the BARKING starts, continues, and because I try to restrain them, they then turn on each other.   Any suggestions?
