If it's a cat or dog, put your hand into a fist and let them sniff it. If the dog/cat responds well gently pet it. Never approach an animal that seems anxious or doesn't respond well to you approaching or trying to touch it.
funny you say it! I had this encounter...or story...this dog was named demon...that's what his owner called him! I said, "don't you believe that's cursing it?" and they were like "possibly..." and abruptly the dog became viscious. They said, "he's never like this." I said, "Watch this...I bind Lucifer..." and the dog the second I mentioned that stopped, turned and was as still as a puddle..." lol!!!!! So pray over them!
