Can I be picky?

First off, you should be grateful the owner is being completely upfront with you. How many comments on this board are about owners not telling sitters everything they need to know about their dogs? But I digress... Obviously you don't want to take a chance with the SA dog. Until they know how he'll cope while taking Xanax, there is too much risk, not only to your home but also to the dog itself.

Sure, you can suggest the doggy brother could stay with you but it seems doubtful that the owner would want additional work dealing with two boarding facilities, plus the kennel might have a discounted rate for two dogs from the same family.

Yes, you can choose to turn down the job. If it's already booked, then cancelling may impact where you show up on searches. My experience with two dogs from a household where one is much more than a handful and the other is easy going is that the owners recognize the issues and do not want to split them up.

I care for a lot of dogs with SA, though they're not taking xanax. From your profile, it looks like you stay at home with the guest dogs and do not have any pets. If realistically you/your family's plans are that you will not be leaving them alone during their stay, then you may be able to care for both brothers.

One option you could offer is ask the dog mom if she wants to test it out for a few hours or up to one night this week. That would reassure both of you if it was a good match before the weekend,

It's always best to go with your gut and be politely honest. If you're uncomfortable, it's best not to push it. Also, similar to what other sitters have said here, it's unlikely that the owner will want to split up her pups - especially because of the SA.

I actually regularly sit a pup that's on Prozac. He's a sweetheart 99% of the time, and only acts out when kenneled or left alone. Because I work from home, I make sure that someone is always able to be home to keep him company and I have no issues. Of course, it is additional work, so if you're not comfortable that's totally okay. It's also reasonable to request a higher rate for extra attention. Most dog owners know you can't be there 24/7 with their pups - so if you need to be, I think it's fair for your services to reflect the extra level of attention.

I would recommend discussing your concerns with the client. Rover doesn't want your to put yourself in any situation you are uncomfortable in. Rover allows you to create your own business and policies. After discussing your concerns with client, I would archive or edit the request to your discussion.
