My old neighbor is an EMT (or firefighter, I can't remember) and just got a dog (adult), and he knows very little about dogs.
He is being advised that it is a-okay to leave a dog alone for 12.5 hours (24 hours actually, with someone stopping in halfway through to let the dog go potty). Apparently, some other people at the station do it with their dogs. Saying that the dogs 'adapt' to it.
I have given him general ideas on why that is a terrible plan, but I am looking for something more concrete.
What are some of the medical problems that could arise from forcing your dog hold their bodily functions for that long?
Any other info on psychological trauma this may cause is also appreciated.
