My boys love the water. Banjo more so than Foxy tho.
Because im a nice mummy I have lead my two down to the river to let them roll and have a play ( didnt ride as don't want them to associate riding on the beach as the same as playing/rolling on the beach)
They loved it! Banjo enjoys rolling in the shallow water, he digs a little hole in the water then lays down in it

so cute. They also paw the water heaps.
In summer on really really hot days I go out with the hose and they just stand there and let me hose them off

not tied up or any thing....not even a halter. :P
And Banjo enjoys a good swim to :P
