Polonia Triangle is in the lower right corner of Wicker Park. It's a busy area due to the concentration of train and bus stops lining its triangular shape. If your dog is excited by lots of movement, this may not be an ideal place for walking. If they aren't, however, this is a great place to stop, rest, and people-watch while on a leisurely walk. A water fountain offers a bit of a view and it's well lit at night. There's not much for your dog to sniff at, however, as its footage is covered by pavement. Dean Playground Park is exactly what it sounds like: A playground. This may be a great spot to stop with the kids, but dogs are not allowed within the park. Plan accordingly if you're out with the family four-leggers as well as the kiddos.
Wicker Park is centrally located within its namesake. It has picnic tables, but also open grassy areas which would be perfect for foregoing a table and picnicking on a blanket. The grounds are well-maintained and you'll see many blooming beauties during the spring and summer. Mature trees line the park, giving you the option to rest in the shade when throwing the ball around leads to you and your pup panting. There's also a water feature, playground, and designated dog park where you can enjoy watching your pet socialize. It's not covered with any grass, however, so during rainy seasons, be prepared for mud.
Walsh Park, a two-acre park located along the Bloomingdale Trail (part of the interurban 606), is just a little north of Wicker Park. A popular spot for young families and teens due to its favorite amenities - basketball hoops, open field for sports, and playground - it's also a great place for dog-owners because of its designated DFA (dog-friendly area).
