i currently own a yorkshire terrier male who is 8 years old next month. we used to have a springer with him who sadly went to the rainbow bridge 4 years ago, in that time we tried to get another springer spaniel pup with our yorkie, however when we brought her home our little yorkie went mad, was shaking and foaming at the mouth with excessive drooling and sadly we were too worried about him and gave the pup to a friend, however we would love a second dog, we are so confused why our yorkie reacted this way as he grew up with another dog with no issues. any advice would be great.
thanks
