Who is responsible?

This sounds stressful. To set yourself up for success, I would scale back your offerings. Don't offer meds or take puppies under a year old for at least 6 months. Both of those are added responsibility and added stress. Quite a few Sitters don't offer these options. Make sure your calendar is up to date with your actual availability.
Any requests that come your way that don't match your profile / availability, decline, don't try to negotiate, "thank you for your request, unfortunately I am not able to accommodate your needs", or say nothing at all. Remember, Rover is just a platform for people looking for a match. You won't be able to match everyone that requests your services. Some pet parents simply go down the list without reading profiles. Don't take it personally. If you don't take unkennelled pups but someone has an unkennelled pup, don't expect them to change. No one is at 'fault'. It's simply not a match.

All the best!

Lisa that is extremely odd and makes me think perphas you're leaving out some details. I've had over 8 people that I rejected. Some because they didn't get back to me, some because wasn't open for dates, some because they selected someone eles. I have not been "booted".

Just because your profile says crated doesn't mean puppies are exempt. I have a puppy thats been crate trained since 4 months old. There is a separate option to select you don't want puppies. I am not aware of ANY medicine that requires you to give to dog every single hour for 24 hours. If you don't want to be tied to schedule for meds like for diabetes etc, simply don't say you give meds. If you have to work one of the days of the week, make sure your calendar is up to date and reflects that info. If the owners cancel, that is never your fault. If you cancel the stay (for any reason) they will flag your account and investigate. If people dont come to meet and greet, dont accept the reservation.

It honestly sounds like you were trying to do too much. When you do a lot it's very easy to get overwhelmed. I had that same problem at the beginning as well and I had to learn that there are certain dogs that did not fit my lifestyle. It was up to me to properly notate it on my profile. Not the written part, but the part rover uses to match you to a client. Thats your responsibility. I could not accept the dog and then go back and say oh wait I don't take dogs over 100lbs. That's not fair to the client. Fyi most senior dogs do not have patience with high energy dogs especially young ones. So if your dog is young or hyper, it would not be a good idea to accept older dogs. By older I mean any dog over the age of 7. So don't put you can do senior care if you have a 1 or 2 year old dog. It will eventually cause you trouble.

I've found my biggest help has been updating the preferences within Rover so I don't get dinged for saying no to a request that legitimately doesn't fit. For puppies, I have the box checked that said I don't accept dogs under 1 year. For walks/drop-ins/daycare I keep the calendar updated with my available times and days. Some things though are out of your control, but I don't think that's necessarily Rover's fault. If an owner contacted me because my profile says I can administer medication, but then expected me to be available for that 24 hrs/day, there's not really filter within Rover that could prevent that (I suppose they could leverage the frequency of potty breaks?). I'd use the archive request "dog wasn't a good fit" and cross my fingers that it doesn't effect my ranking too much. Same with having your own puppy, Rover doesn't have owners fill out an extensive profile about their dog's stressors before searching (and honestly, even if they offered it we all know plenty of owners wouldn't fill it out anyway!) I don't expect Rover to read each and every message that is sent in order to make sure sitters aren't getting docked in error.

I'm sure it depends on the area you're, but honestly I'm not sure Rover's algorithm is worth worrying myself over. I know I'm a good sitter, my clients know I'm a good sitter, and I've turned down a fair number of clients and was still the top boarder in my area (until I set myself as repeat clients only because I need a break!). So continue to do what you can, but unless Rover changes there's no point in stressing yourself out about the things you have no control over.

Hi, Lisa. I think the best thing for you to do is to make your situation as clear as possible on your profile, though I realize that not all owners pay attention to the profile details. If you are unable to accommodate puppies, I would be sure to include this in your profile and if you ever receive a request for a puppy, politely decline and mention that as stated in your profile, you are unable to care for dogs under the age of 12 months. As for medication administration, you do not have to select that you are able to administer oral or injectable medication. I am unsure what you mean by being available 24 hours a day for medication? Of course there are going to be price-shoppers or people who find others, such as family members or friends, to care for their dogs after initiating a conversation with you. That's okay! It happens to everyone. Just archive their request appropriately and look forward to your next request! It looks like your profile is not live right now, so I can't tell which services you offer. I am assuming you offer boarding, but perhaps you would be better off with offering traveling sitter services, that way you don't have to worry about others interfering with your puppy?
