I would want my dorg back. (Most of the time I feel that way.)
I wouldn’t want her bloody, either with her own or any other dorg’s (or dog’s, or other animal’s… or your) blood on her.
I wouldn’t want her to have been fed anywhere else.
I wouldn’t want to have to fish for cash on the spot when you arrive at my door, either to take her for her walk or to return her; I’d prefer a weekly or monthly billing.
I’d want assurance that all of the dogs (or dorgs) are up to date on their rabies shots. (You’ll want that assurance, too, in case one of them ever nips you!) Many owners may not think of that, but if you’ve ever put a dog in a kennel overnight then you know that without the certificate, the dorg’s not staying. So you’d better think of it.
I’d want you to be dependable and on time and consistent.
I wouldn’t want you to be subcontracting the job to someone else because you were bored, had a headache, the weather was bad, your favorite show was on… yada yada.
I wouldn’t necessarily care (nor even know) whether you were a dog lover or not, but you’d have to be able to stay in control, and do that humanely, and be careful with all of the dorgs.
And I’d want you to do that for a very reasonable price.
