Describes whether dogs are legally allowed in a certain area (like a park) or if an amenity is meant to be used by dogs (for example a place to drink water).
As an access restriction
Due to a variety of reasons dogs may be explicitly (i.e., by means of signage) or implicitly (e.g., when local rules and regulations stipulate it) banned from certain ways or areas. The following tag-values can be used:
Some of these tags can be implied and may not need to be explicitly added. For example, dog=yes is not usually needed, particularly on highways (e.g. highway=footway), as this is the default where foot=yes is specified or implied. In the same way, dog=leashed tag may not be needed in jurisdictions where leash laws already mandate dogs be leashed on public roads. Also, the dog=unleashed tag may not be needed within a leisure=dog_park as this is implied.
Because dogs usually can't read signs, using dog=* as an access=*-value implies that the prohibition is aimed at people walking (or otherwise accompanying) one or more dogs, and should be understood as an additional restriction to the mode of transportation of whomever is taking the dog along — i.e., for routing purposes this tag should usually be seen as an addition to foot=* (although bicycle=* is not unthinkable).
Leashed or unleashed
It should be assumed that dog=yes implies no information about whether dogs are allowed unleashed as well. The default is that local leash laws should be observed; often this means that dogs are not allowed without a leash, except for specifically designated areas (e.g., leisure=dog_park, which implies that dogs are allowed to roam off the leash).
In many countries assistance dogs (such as guide dogs) may not be barred access from places accessible to the general public. Any use of dog=no should probably be understood with this exemption in mind (i.e., it is not necessary to explicitly allow access for guide dogs, because this is implied).
