Are any of your chihuahuas scared of their own reflection, or yours? Ponyo was like that for a little while until I came up with an idea. I left a mirror at her level for a few days and played with her in front of it until she was intrigued! Now I catch her checking herself out from time to time...
I know that chihuahuas respond affectionately to others of their kind, so this was very interesting to see her go from "alert bark" scared to "Hey, lookin' GOOD!" in a week or so.
It always helps to have Big Bear around, too. He helps us insecure girls deal with new scary stuff!
Bear: Don't u have treats wiv dat camera usually?
