I used to breed and show Australian Shepards but because of my bad back I had to find a breed that weighed a lot less. Now I own a Papillion, given to us 4 years ago by a lady was going to take her to the pound because of behavioral issues. A little bit of training and discipline and lots of love Brought that little one around.
Many people think that she's a long-haired Chihuahua but they are totally separate breeds and come from different continents. Papillions originated from European Spaniel stock. The name Papillion means butterfly in French. Their ears stand at attention (unless they are Phalen and then they droop) when they are alert and move just like the wings of butterflies. They are very intelligent and feisty little dogs who do not know that they are little. They guard well, chase away larger dogs, and stand their ground with livestock. Mine is the best guard dog for inside the house that I've ever had. I've had cats and hamsters and fish but I much prefer my Happy Papi!
Papillions are not well known in the US. Here's a web site in case you are not familiar with the breed:
