We have used Owners Direct too, with no problems. I think the reason i like this site is because the owners actively seek out people with dogs, rather than tolerate them. IME, although on a lot of sites it says dogs are allowed, they then:
Charge per night, per dog
State that dogs cannot be left at home alone
Have restrictions no where they can go in the house
Do not necessarily have enclosed gardens.
The places i have found through this site have all been dog lovers/owners. I have never paid extra for my two, dog towels, beds, even bowls are often provided, along with copious amounts of throws, so that if Fido likes to lounge on the sofa, he can😊
They also tend to have enclosed, dog proof gardens, which is brilliant and some will take up to six or seven dogs!
We recently went to a fantastic place in the north lake district, pure luxury - the master suite was incredible and we even had a cinema room.
Dogs loved the garden too.
