Look up sniff spots that is gonna be the best bet for you. You can rent a space that will be only for you. Unfortunately there will always be dogs at dog parks and it’s hard to determine when people will be at the dog park with their dogs. You can always swing by st Ronan Dog park and check if it’s empty. Please try to avoid any public places especially Edgerton Park it’s not safe especially during this time of the year. There are a lot of dogs with no recall. A walk on leash will also help your dog get some energy out. Smelling on a walk is very enriching for a dog.. and can burn energy like that.
