Yes it is the same thing. There is a .27% and a 1% solution. If you read back through this thread someone talks about why it has to be injected into certain kind of animals.
I use .27% injectible for grower and feeder pigs. I use the .27% solution because you do not have to dilute it (Im not that you have to dilute the 1%, i just know alot of people do), it is easier to measure because I am giving 1 1/2 - 2 cc instead of trying to measure out 1/4 or 1/8 cc.
It is not labeled for use in dogs, but as you can tell by this thread everyone uses it and it works. It should not be used in collies, collie crosses, and a couple other breeds.
