Brohard Paw Park (Venice) - 2018 All You Need to Know Before You Go (with Photos) - TripAdvisor

I haven't taken our golden doodle yet to swim at Bark Central in Inverness.
But it's on his wish list.

It's a very small pond at DDRR, actually more like a bathtub.

It's 44 x 66 x 11 inches deep and shaped like a dog bone. Amazon.com : One Dog One Bone Dog Pool (Bone Shaped) : Pet Supplies

Even a beagle couldn't swim very far in it. It's basically just to splash around in.

I don't know about hotels, but I can vouch for the fact that there definitely is a beach, and it's beautiful.

You walk into the dog park, which is also fantastic, with plenty of watering stations, a bathing station, places to sit, shade, etc. There is a wooden walkway, fenced, that leads from the park to the beach. Your dog can race down the boardwalk and end up on the off-leash beach. It's fantastic.

You can drive a little down to a beachfront restaurant where you can sit outside with your dog. It was very crowded, so we didn't eat there.

I suppose you could google dog-friendly hotels in Venice Beach and find one nearby.

I'll vouch for it as we've been many times. It's in a Pinellas county park ( Fort Desoto). There are two adjacent fenced dog parks ( big dog and small dog) with a dog washing hose and drink bowl in each. Close by is the off-leash beach where the dogs can swim.

Fortunately for me, my dog (96lb yellow lab) loves golf cart riding so she is in heaven here in TV. She'll take a swim when given the opportunity, but doesn't miss it either. I wouldn't let either of my dogs swim in the ponds and lakes here and wouldn't even let them roam off leash near them - gator bait.

Thank you !!!! I was wondering if dogs were allowed to ride in the golf carts ! Do you strap her in ?

My Koda is 92 lbs, age 9. Loves riding in the car.

Depends on the dog. If mine were looking for the opportunity to jump off, I would probably work out a way to restrain her better or just not indulge her in riding at all. She is not interested in getting off the cart unless and until I do. However, I do keep her on leash, even on the cart, and keep it semi-taught at all times so that she knows it is there. She's about 96 lbs and loves riding in or on anything, but especially loves cart riding because of all the sites, sounds, and smells. We used to have a permanent place in a large campground where carts were the main source of transportation, so she has been riding on them since she was a small pup.
