With 4 dogs, for the future, post a lot earlier, because there are less sitters that can handle 4 dogs, but there’s still sitters, just less of them. So all it means is that you need to give more time to find the perfect sitter for you, ie more than 2-3 months notice.
But here’s a couple of tips to tweak your ad. Hope this helps, please don’t take it personally, most of your profile is great, there’s just a couple of errors with it.
At the moment, your main image is of your 4 dogs, so straight away without sitters reading a word, sitters need to decide in that moment whether they can handle 4 before they click into your profile, so you’re probably limited to couples, and that’s before they’ve read anything about you having an acre for them to play in which is a huge bonus.
While dog sitters love dogs, leading with your pool image as your main image will be even better for you, given you have 4 dogs, as that may appear at first as being overwhelming to some… that didn’t realise you had an acre of garden. Your pool is your homes biggest selling point in your particular scenario, over the dogs.
You also mention 2 rescue dogs in your title, and then there’s 4 dogs in the image/text, so there’s an imbalance. So at first glance it makes things look iffy, at first glance things just don’t add up, and when things don’t appear genuine, sitters just scroll on to the next home, where everything makes sense to them. So tweak your title too, I’d remove the bit about 2 rescues, and say you have an acre instead.
Hope that helps, you’re place looks lovely, and your dogs are cute, so I’m sure your perfect sitter is out there, if you just tweak your profile a little, so that they definitely click into your ad.
