Paddle North
Paddle North's Up Dog inflates to 65 x 42 x 6 inches, weighs 13 lb, and carries a 250 lb maker capacity. Its 1.2 mm drop-stitch PVC body, weighted mesh step, GripTrak pad, four D-rings, and two included 50-inch straps create a broad platform for salt or fresh water, but buyers need a separate compatible pump and should treat the capacity as a maker specification rather than a safety guarantee.


WaterDog Adventure Gear
The WAG SLM-12 mounts to a compatible human swim ladder with at least three steps and standard rungs up to 1.5 inches, with an accessory hook kit available for larger rungs. Twelve steps provide 44 inches of rise for dogs up to the maker's 130 lb limit, and the roughly 18 lb assembly requires no drilling in its standard setup; compatibility is strict, and the unit must be moved or stowed exactly as instructed around human use and boat travel.


WaterDog Adventure Gear
The WAG HSM-10 is a ten-step pontoon system that mounts through flush threaded deck inserts and rests adjustable lower legs against the pontoon. It needs 18.5 inches of open deck width, serves decks up to 24 inches above the water, weighs about 23 lb, and carries a 130 lb maker limit while leaving the human swim ladder open; permanent drilling and exact deck geometry make pre-purchase measurement essential.


doggydocks
doggydocks Large is a rigid 74 x 21 x 5-inch floating ramp for boats, docks, pools, and yachts, weighing 47 lb. It includes a SnapBag system listed at 100 lb of buoyancy and a 12-inch extension that adds 43 lb, but mounting kits cost extra and those buoyancy numbers are not a published maximum dog-weight rating; owners should obtain maker confirmation for their wet dog's weight, freeboard, and mounting setup.


BOTE
BOTE's Hangout Ladder is a 5 ft 6 in by 4 ft inflatable U-shaped access ramp for people and pets, with a weighted submerged mesh ladder, EVA/BVA traction foam, grab handles, ten DockLink D-rings, and a 300 lb maker capacity. It works without a swim platform and packs into an included sling, but at 44.5 lb it is not lightweight, requires 6-8 PSI inflation, and does not include a pump.

LilliPad Marine
The Easy Step is a permanent 44-inch, five-step replacement for most stern-mounted pontoon ladders when at least 22.5 x 13 inches of mounting space and suitable structure are available. Three extra-wide upper steps, two ergonomic lower steps, a submerged third oversized step, all-metal construction, and a 400 lb maker capacity support people and dogs, but the $1,299.99 price and drill-in installation make it a specialized premium upgrade.
