Dog is too scared to walk

Hey all. Posted a few times before, but now we have a whole new behavior that I can’t get him to shake. My dog is very afraid of thunderstorms/fireworks. He starts shaking and tries to find the smallest space to fit into. I’ve dealt with this for more than a year, and finally I got him some trazodone to help calm him down. However, he refuses to go on walks with me anymore. Nothing bad has ever happened on a walk besides maybe getting caught in some thunder. I think he is associating thunder with being outside. The weird thing is when I mention outside or potty he is enthusiastic. He goes straight to the car because he wants to go somewhere, yet he won’t walk with me around our neighborhood. I just took him to a nearby lake and he refused to walk. He just wanted to jump in the car. He also refuses to get out of the car when we get home. I’m at a loss on how to get him to stop associating walks with thunder or fireworks. My poor buddy needs the exercise!

What is this wound? swollen and oozing a bit, senior 14yo English bulldog, hasn’t been eating all week (other than a few bites) but drinks water. Tried the emergency vet clinic today but waited for a long time and no vet came see us. Thought I’d try asking here until we can see his vet on Monday. TY

Found this in/near dog's crate

I'm not sure if this belongs in this subreddit but we're hoping to find some answers! This is the second time we've found this in and near our dog's (indoor) crate. The first time was a few months ago and we never figured out what it was. Both times, we found it after our dog was in his crate for a few hours while we weren't home (he's always crated when he's alone, so this isn't atypical) but the crate was in different rooms of the house each time. The pieces are wet and kind of rubbery and can't be easily cut with a fingernail. They just smell like dog breath. Some pieces are inside the crate and some pieces are right outside the crate. We would assume they were pieces of a toy/etc., except our dog doesn't destroy toys and is supervised at all times when he's uncrated. This time, he picked a piece up and ate it before we could pick them all up. Last time, he acted totally fine afterwards and so far, so good this time. The red substance could be blood/etc. but he also ate some watermelon today (he didn't last time, there was no red substance last time) which is kind of what it looks like. We have not found any toys that it looks like this belongs too and the only thing in his crate with his was blankets. We do have a fenced in yard but he's always supervised outside and nothing outside resembles this either. Anyone recognize this?
