He is the biggest scaredy dog and frightened by everything. It's not possible at the moment to narrow down the source of his fear. He thinks you are throwing things AT him instead of for him, including treats. He is so afraid that eating treats is a feat of bravery. He has lived with us now for just over 2 weeks, so it's early days, and I have found a lovely trainer to help him overcome his fears. I wonder if this will be a lifelong journey for him, learning how to be a dog?
