Not only is he risking getting hit by a car but the kids in this house is terrified of dogs. Bringing this many large dogs into my house is not an option and I know sooner or later they will either get hit by a car or have to be put to sleep to keep from being sued by this neighbor. I have tried chaining them up but they struggle so much I am afraid it just makes it worse. You may need to find a location they are secure with you riding out a few storms. Gradually you can disappear.
Tranquilizers are a temporary solution.
You may try getting used to a recording of a storm slowly increasing the volumn and bass. They don't seem to bother her, but I can feel them when I pet her. Thank you for you help. See if a canine antiseborhea shampoo and alcohol wipes help. I use the liquid chocolate flavour brand and give my dog worming medicine regularly and follow the instructions to a 'T', noting that if the dog is sick the dose is not to be repeated.
