@Joe2803 Regardless of whether a place is listed as pet-friendly or not, hosts will want to be informed that you are travelling with a dog, and this should be obvious if they state they charge a pet fee. How would they add the fee to your booking if you don't tell them about the dog?
Also, many hosts want to know because they will prepare the space differently if you are bringing a dog. They may remove some rugs so they don't get covered in pet hair, they may provide you with some clean, but worn sheets or towels to put on the furniture if your dog sleeps on the sofa or bed, if they are dog lovers, they may set out dog bowls, and leave some dog treats.
And some hosts, even though it says pet-friendly, have restrictions on the size of dogs they accept or how many. It's just respectful to let the host know beforehand. Hosts generally like some information as to the make up of your traveling group- whether it's a couple with kids, two couples travelling together, a gals or guys get-away, dogs, cats, whatever.
As Colleen advised, just leave a brief factual response to the review making it clear what happened. You have a bunch of good reviews- hosts don't believe every word of every review if they see it differs from your other reviews, anymore than guests would believe some review claiming the place was filthy, when the host has a dozen or pages of reviews saying it was lovely and immaculate.
