text: If it's a small model of a horse it's a horse doll or a toy horse.\n\nIf it's a stick with a pretend horse's head on it that the child straddles and runs along with (while making horsey noises) - it's called a hobby horse.\n\nIf it is a totally imaginary horse, existing only in the child's head, then it is an imaginary horse or pretend horse.\n\nDoll horse is definitely not right.
