Consider the Park's Design
Some dog parks feature one open space that is shared by dogs of all sizes while others are divided so that smaller dogs can run free without encountering their much larger friends. While some dog owners don't mind the mingling of all dogs, others prefer some division for their own peace of mind. If you're in the latter group, you should ask about the division of the dog park when you inquire about renting an apartment.
Make sure that the community dog park is surrounded by a well-maintained fence of adequate height to contain even larger dogs. You don't want to discover a hole in the fence by watching your dog squeeze through it and run toward the road or into the parking lot. Also look around the dog lot to identify any potential dangers.
Ask About Restrictions
Some dog breeds are known for their aggression toward other animals or even unknown people, so many apartments place restrictions on the breeds allowed to use the community dog park. Always ask if your dog's breed is welcomed into the apartment community, and make sure that your dog is properly trained before allowing them off the leash at the park. If you have concerns about your dog meeting up with aggressive breeds, ask someone in management if there are any breed restrictions for the park.
Before taking your dog into an apartment dog park, discuss the issue of liability with the landlord or someone in the rental office. If your dog is attacked or otherwise injured while in the park, are you solely responsible for vet bills and other expenses? They may ask you to sign an agreement stating that you understand the risks of using an off-leash dog park and won't hold the owner of the park responsible.
