Used for my fearful dog (combination of Aspen, Mimulus, Rock Rose), heavily diluted in his water, food, and rubbed on his skin. The combination brought his fears down just a bit - enough for me to have more success training him to cope. Still working hard with him and will order again when our bottles dry up.
This stuff works great, but you do have to be consistent in your use. I have always had to use these types of remedies full strength, though. The water dilution method just doesn't seem strong enough for me. I take two drops on the tongue at least once (I try to do two or three times) a day. I really recommend getting a good book on these Bach Flowers or speaking with someone trained in their use to find the essences that are the ones you personally need. If you chose the wrong ones, they won't hurt you, but they just won't help either.
