we got a aussie, border colliemix. just like many others we bought the 4 in 1. he started out very lathargic. he would not eat or drink. he passed away. we have been so heartbroken. if we would of known before hand we would of never used it. i use to work for walmart and i am very upset that they still sale this crap. please do not use these products. we miss him so much and it pains me everyday to see the saddness in my childrens eyes that there best friend died. please stop this from happening to someone else..
