Yes I believe they are also they are focusing on one trait rather than the health of the dog and the total package. I like the 5-7 lb range myself.
That size dog is self sufficent they can climb stairs or get on the couch etc by them self. You can worry less with them about injury. They are still small enough to pick up aned carry. I have one that is 6lbs and I think that is a great size |
