Dubai Hills Estate and The Springs suit dogs mainly because of what is outside the front door — villa gardens and open green space, plus the Dubai Hills dog park, remove the daily walk from being a planned outing. Apartment living in Marina or JBR works too, but it depends on proximity to Black Palace Beach or an equivalent pet-friendly stretch rather than the building itself.
Community master rules and individual tower policies sit above whatever a landlord tells you verbally, and they can ban a breed or pet type outright regardless of what the listing implies — get this in writing from the building or community management before signing, not after moving in with an animal that turns out not to be welcome.
