I have zero experience with this problem and I’m just spitballing but I’d consider. (Note that I’m rather stupid, don’t own a home, and uneducated about electrician stuff):
Some kind of epoxy to just totally coat the outside. Slather it on and it hardens and I don’t have to think about it
build a little enclosure around that bit so it’s living a bit more “inside”. probably impractical but a fun challenge
wrap electrical tape, then pipe insulation. Tape over the pipe insulation then brush on something that cures into a waterproof seal
Huskies’ natural environment is like Siberia isn’t it? Would it be okay to shave a husky in a tropical climate (assuming the decision to own a husky in a tropical climate’s too late to undo)
