I don't know what you did, but I imagine if you felt someone you trusted pull energy out of yourr system unexpectedly how you would feel!
I remember I tried doing Quantum Touch energy work on my cat a few times when I first started learning it. ( QT is where you raise your own vibration by sweeping energy up from your feet through your body to your hands). My cat would give me a stinking look and get up and walk away, every time!
I was told by someone who really likes animals that you have to mentally or verbally ask permission of the animal if you are going to do energy work on them before doing it. I tried this and my cat will tollerate some QT energy now!
I'd have a look at the Quantum Touch website
Quantum-Touch: The Power to Heal and chat to the people on their about energy and check with your dog first before you pull energy out of him, next time.
or better still do QT on him instead.
