Theo dore able

This is Theo, my six 6 year old chihuahua, i have four chihuahua's, three of which are pets as therapy dogs. This one being the odd one out, he would never make a pat dog as he has a grumpy streak.
He is my favorite one, yes i know you should'nt have favorite's but there is just something about him, he is very much a morning dog and will roll over, squirming for attention but catch him after nine at night and he is so grumpy, best left alone then.
