Rosie's Dog Beach is a great place to go, check out this fun video of the dogs on the beach. Doesn't this video just makes you want to take your pup to the beach?
I also like Recreation Dog Park just off 7th street. Two areas that are fenced one for smaller dogs, and another larger area for the bigger dogs. http://www.recreationdogpark.org/
We have some great patio restaurants on second street in the Belmont Shore area that allow dogs to sit next to their owners while they enjoy their meal.
Parker's Lighthouse is another one where the Queen Mary is in view from the pet-friendly outdoor seating. Locals applaud the seafood fare here as well.
Cafe Sevilla in Long Beach serves up tapas to the young crowd and will welcome your pup to its patio.
Ambrosia Cafe is a great place for breakfast and lunch with an extensive menu and bar; plus their garden patio has a fireplace and welcomes dogs.
Frosted Cupcakery makes amazing sweets for both you and your favorite pooch and ... what dog wouldn't love a Pup-cake?
Schooner or Later has a large outdoor dog friendly patio. It is best to come early in the morning with your dog on weekends. FYI, this place is know for it's good breakfasts.
Georges Cafe in the Bixby area has a great outdoor patio and my dog Raeggie loves the steak salad, he most especially likes the steak part!
We also have numerous Starbucks and other coffee places with outside patios.
Long Beach is a very park friendly city and pets can walk the parks with leashes on. A sunny Sunday afternoon can be a great time to take a walk at El Dorado Park and watch the ducks.
Of course we also have all the great bike trails. Some people have a bike trailer and Fido rides in the back. Lots of exercise for everyone! For more information on living in Long Beach just let me know, I have lots of ideas I can tell you about!
