Osiris, the dog is a Dutch Shepherd who has an uncommon relationship with the mouse, Riff. Riff was rescued when he was just 4 weeks and nursed back to proper heath with help of a syringe. Since then Osiris is nothing but kind and friendly to Riff as his own family.
Osiris was a rescued one himself. He was abandoned in a parking lot when he was merely a pup. These new owners of him took him in and gave him a shelter. We can see why he is so fond of other foster animals.
After all, Osiris has been trained as a therapy dog. He has all the patient and the understanding in the world to help his owner to take care of other animals as well. He is kind of the guardian to them now.
