Arano no Sakebi Koe: Hoero, Buck

Adaptations of western novels, both show the bonding between mand and a dog/wolf in a wild. They also give off a somewhat nostalgic vibe. 

Call of the Wild and Silverfang are both from the 80's, centering mainly around dogs (sled dogs in the former, bear dogs in the latter). They're both worth checking out, especially if you're into canines in general and animes featuring them, OR if you're just looking for a great adventure story. Do not get let down by the fact that they're both a bit more on the aged side - just give them a chance! 

If you're looking for an adventure movie about dogs in beautiful settings, both of these movies are for you! Call of The Wild is a bit more realistic and violent than The Tibetan Dog, but both have a strong and loyal dog as a protagonist.  

The sequel to GNG. Call of the Wild, GNG,and GDW are all about dogs living in the wilderness.
