Let's make it simple. I am reviewing this as a dog -owner. You'd be crazy to go to a dog beach if you are not a dg owner and are just looking for a typical beach day. THat is, assuming your are not a dog lover.
-north end of beach is enclosed by the San Diego River
-great selection of nearby casual dining, all within walking distance
-there is a place to rinse off before you get back in your car (but it is not convienent.... a short hike south passed the rock wall (and people beach)
-new bathroom facilities near the foot wash
-most owners are good with letting dogs be dogs (I.e. playing, growling at each other, humping, etc.)
-its OB - the most laid back part of San Diego...what's not to love!?!
-OB is not exactly centrally-located, nor is there easy access Unless you are near the airport, mission bay, or p-many owners are out of touch with their dog or just not very dog-aware, expecting theirs to not have to share a toy or yours to no be interested in the treats in their pocket
Point Loma, it is a trek to get there; best to make it a half-day event, and stop for food in OB (HODADs is highly recommended)
-on peak days (summer weekends, Friday evenings) parking can be an issue; always be prepared to walk a few blocks if needed
-South end of beach is marked by a rock wall, but the dogs don't know that there is an invisible line there they cannot cross; if your dog doesn't always do as you ask, do yourself a favor and stay on the North side where he is less likely to stray to where he shouldn't be
-In general, not as clean a beach as Del Mar dog beach
-there always tend to be a few jerks - irresponsible dog owners that do no pick up their dog's waste
-on the same note, I wouldn't count on all fogs being vaccinated or fixed (many are clearly not fixed) - hold off on brining your dog here until he is both fixed and vaccinated
Please be smart. Don't go to Dog Beach with your young children and expect to have a nice peaceful picnic on your own blankets while you cut up salami for sandwiches.
