I was at Petco today looking for hemostats before taking Abby in for her last check-up before the puppies come, and they had Thundershirts. I bought one and when I got home, I tried it on Chumley. Epic fail. lol Should have know it wouldn't work on a half Basenji. So I tried it on Reggie who, if I leave the dog room, with bark constantly with his annoyingly high pitched bark until I come back. Total success. I was able to leave and go into the living room and talk with my son and not one bark from Reggie!!! It was awesome. I will try it later on Delilah when my brother in the wheelchair comes home and see if it stops her from barking at him.
