Hey JP how did you train you dog to go into the black tub? Our dogs love getting into the water at the local swimming hole or down at the river (when it has any water in it) but there is no way they will get into the black tub (same as yours) that we bought for the same purpose as you use it for.
I grab and put them in the water and while I hold them they are happy but as soon as I let them go out they get.
Any and all suggestions are welcomed.
