We used one of these for our yorkie when he was around that size. We bought it at Petsmart. We had to buy a smaller collar for it if I recall because the collar was too big.
It really helped us. We especially used it when we traveled and had to stay in hotels. However, after he realized that the citronella did not hurt him, he would sneak in a bark here and there. But I still think overall it really helped. I would recommend it.
