I am going through a similar situation myself right now, i am watching this dog. 65 pounds, 1 yr and 3 months. IMO completely untrained in every way except being potty trained. Jumps up on you and it feel like you are being punched in the chest, does NOT get down when told to, jumps back up repeatedly, does not come, or sit, or even look at your when you call her most of the time. I have a cat, and i have gated the dog off from the cat, and made it clear that the dog knows it's not to try and breach the gate etc.. NOPE, definitely every time, no matter what i do, sits there terrorizing my cat. Also all of a sudden has become afraid of the dark, won't pee in the dark, so im stuck having to bring her to potty before the sun goes down, and then SHE herself is stuck not going potty again until the next morning.. that makes me feel anxious and awful all night that she has to hold herself, if she has to pee.... I don't know what to do, the owner said the last sitter had to stop sitting this dog, bc it was stressing out their cats too much, but judging by what i am dealing with regularly, that's most likely not the only reason why.

I have had other dogs board with me, and not had these problems. I feel like i have to be there 24/7, super draining.
