To the northwest, you'll find Roosevelt Boulevard and Welsh Road, the location of most of Pennypack's businesses and restaurants. You'll find Pet Valu and another pet supply store nearby, situated in strip malls along Roosevelt Boulevard. Grant Avenue Pet Grooming lies north of Roosevelt, closer to more of the local businesses. The Boulevard Animal Hospital is nearby as well, in case of emergency.
The neighborhood is bordered to the east by the Northeast Philadelphia Airport. While it's not quite as busy as Philadelphia International Airport, planes do take off and land there fairly frequently. If your pup isn't fond of loud noises, consider avoiding northeastern Pennypack. In addition, though the area is very residential, there are several busy roads. Roosevelt Boulevard is a multi-lane road with medians, so take extra caution when crossing the road.
While there aren't any dog parks in the immediate area, Pennypack Park still offers miles and miles of hiking trails, perfect for wilderness-loving dogs. If you don't want to visit Pennypack Park, there is a small playground northeast that borders the airport. In addition, Holme Crispin Park to the southeast offers a foray into the natural Pennsylvania setting.
