Hello. I rescued a dobie mix from a hoarding situation. They were stacked in crates and eating, sleeping, living in feces. He was good for the first view weeks of being home. But recently, I've noticed some tiny behavior changes. We go to the off leash dog park daily and he avoids the fence with cars driving by. He is afraid of people and would run the opposite way but is approaching women more (which is good) but now barking at men. He was afraid of a certain dog at the park but stood up to him recently (which I'm iffy about). The major problem: he does not want to be outside on a leash to go to the bathroom unless we head to the car to go to the park. He tucks his tail and pulls me either to the car or house. He's scared of every little noise and I don't want his fear to turn aggressive. I work at a shelter and I know what happens to dogs that bite humans. I can see him escalating and I want to stop it before it's too late. I have a new trainer next Wednesday but if I can get some tips to make it to Wednesday. I recently started leashing him while at the dog park on the car side to make him deal with the noises. He pulls me the other way but does not tuck his tail. So I feel like this is good? I only do it a few times to not push him past his tolerance. Attached is a picture of him outside the house, not wanting to pee and trying to convince me inside. Any tips will help until I see the trainer next Wednesday. Thank you
