I have a two month old terrier/chihuahua mix(1/2 chihuahua + 1/2 terrier), My puppy is absolutely adorable! She looks more like a terrier than a chihuahua. She has a yorkie face, yorkie coloring and a size of a chihuahua.. She is a small dog. She's full of love and energy.. I'm scared because she don't like to eat puppy food.. She just smell it and go away.. I don't know what to do. Is it okay to give her a milk? And she always scratch her ears.. Do you have any advice? Thanks a lot!
