Well I got the 12v adapter (steps up to 24v) in the mail today. Considering my pup has no room for a battery, I may just buy a walmart deep cell today and charge with jumper cable (or 2 small solar panels) and go from there. I'll update here what I do or figure out!! And please keep idea's and concerns coming. I am very limited on space as my TV is small and my pup is even smaller!!
