I have a dog that has 3 months and 3 weeks and I walk with her regularly along the street since she was 2 and a half months, I also have an old dog (15 years) that's blind and they live together.
But my younger dog is afraid of any kind, size and age dog we see on the walks we do. She hides behind me, cries, and hide her tail between legs, and when the other dogs tries to smell her or anything she growls. She has met younger dogs, male, female, older but never a rough dog, so I don't know why she's always afraid.
What can I do to help her get over her fear?
