Horse or dog?

See this! The poor horse was rejected by his mother when he was born, saved by his owners and brought up with two labradors... so he thinks he is a doggie... by the end of the movie you can see how he brings freesbies, drinks from a dog's bowl and follows his owners and runs just like a doggie. They say however they want now him to understand he is a *horse* because once he grows up to full size, the dogs will treat him differently...
