I'm trying to remember a short series/film about this pup that was found by a young boy. The pup belonged to a pack of dogs that resembled alsatians but had horns on their head. The dogs attacked the building where the pup was being held as they were vicious and the horns lit up when communicating/when ready to attack. In the end the dogs were destroyed but the boy put the pup through surgery to remove the horn and the pup became normal. My memory of this is very vague so if anyone can remember the name it would be most helpful.

I have just found out from my brother that the cartoon was mainly about ships/robots that joined together in a power ranger type robot formation which had blue legs and red spikes and it was the team of five characters that used their machines to transform. Apparently they wore helmets and the females had wing like helmets and the dog part was just an episode. He also mentioned that they fought against one main bad guy who had a ship under water (he thinks so anyway) and he remembers a bull like creature/robot.

I don't know how I'm getting this from your description, but I have a feeling you're talking about Battle of the Planets/ G Force and mixing in a bit of Voltron and Robotech:
