Lobo

Lobo was originally Mr. Hanley's dog.

After his death Amy takes him back to Heartland, as they are unsure of his name they give him a new one. Caleb suggests Lobo as Lupin is Latin for Wolf and he looks more like a wolf. Lobo is shot and very nearly died, but luckily Ty knows what he’s doing when it comes to being a vet!

Trivia

 * Lobo stopped appearing suddenly because the dog who played him, Nitro, passed away due to old age.
 * Nitro was age 14 when he came onto the show, and the director decided to only use him when necessary due to his age, breed and the heat from the set lights.
