Three brown and black dogs are splashing in the water.
Young puppies are playing with their mother
The ages of the dogs could be something other than young puppies and an adult.  The doges could be male or female so possibly none of the dogs could be a mother.  The relationship between the dogs could be something other than siblings and a mother.
