Silver Fang (1986)

Basically none. A dog gets pregnant. At least two scenes overall show any dog character urinating in fear.

The last four episodes have very severe gore, as dogs get crushed by bears and overall fight together quite intense.

Lots of animal violence occur throughout this anime. Blood is often shown.

Several people and dogs get attacked and killed by various bear attacks. People use weapons to kill animals.

A man chops off one of his legs. The impact isn't directly shown, but we see the act.

A man gives a puppy hard training, beginning with beating it up.

A boy falls into a deep hole, and gets saved by a puppy.

Later episodes have dogs often fighting each other. Several dogs get killed. In various other scenes throughout, dogs kill a few other kind of animals.

Some other animals, including birds and a few boars to name a few, get hunted down and killed, mostly for food.

The final battle is intense: lots of animals get killed, and the battle itself has the most blood overall.

Mild language/swearing may occur. This may depend on which dub the viewer is watching.

In one episode, at least one scene shows a man drinking. This is very brief.

A dogs head is cut off by a bear - the action isn't shown, but the cut-off dog head is. This is the most intense scene in the whole series.

There are cannibal dogs.

There is a bear with several harpoons stuck in his back.

In the last episode a bears head is cut off by a dog, it's shown on screen. This is the second most intense and frightening scene in the series. Although it isn't as scary as the dogs head.

While the violence isn't very graphic, several scenes have some intense parts. Some scenes could get pretty intense for very small children, especially the scenes showing blood, and the parts where characters are either in grave danger or getting attacked/injured/killed during battle sequences. There are several emotional scenes as well.
