Good Morning, Renee! No, Hunter didn't knock anything out of joint because he's not limping around. He seems much better today. The top 3rd of his tail seems a bit swollen and tender to the touch, so I really think he sprained it --over extended it or what not. He can still wag it, though!
I e-mailed a company about the solar paneled electric fence. Saw the battery backup, too. Want to know what the "insulator things" are the wire needs to run through. Looks like that's what I might be getting!
