its normal as a new character that you have difficulty with wolfes.
( in general even when you have advanced example 100 days into the game then wolf and creatures in plains area are tough.... BUT there is a trick.
listen to the sound and avoid going to areas with wolf sound.
In the plains area open your eyes and avoid the bees.
A trick to killing both wolf, bees and other enemys are to press CTRL and kneel and then use your bow to hit them from very far away.. IF you make a success full attack and the enemy is not aware of what is happening then you can often one shot enemys.
So upgrade your bow and arrows ;-)
Els regarding wolf then i use the above trick, but also i jump up on top of big rocks or places hard to get to and shoot from there with my bow vs face to face fighting.
By the way get an axe or a sword and a shield.. If you block and attack many enemys will get shocked and cannot attack for 4 seconds. ( not all ).
But in general the snow/mountina area is dangerous and so is the plains area.
A good advice setup a teleport system so you can jump to an area and pickup your gear if you die. So build a small house with a teleport inside that is more easy than sailing.
Its a good idea to build the house 100m away from the dangerous biomes so you can spawn in safety.. And once yo udid that build a building number 2 in the center of the dangerous biome so you can teleport up on the mountain vs climbing it everytime.

I got carried away... here is the answer you want.
However there is a reason for it hard for a new player.
THe game is designed in such a way that where the player start ( the first biome ) is what you are good enough to survive in.
Once you kill the first boss ( the deer ) and get the ability to mine copper and build copper weapons then you can after that go to the next biome.
And once you kill the boss there you are supposed to level up and go to the swamp.
And after that the mountains with snow
And then the plains biome
ect.

Basicly you are only strong enough to fight the enemys in the biome that you are in or have killed the boss in.
So if you as a new player build a little ship and go to example the swamp area 30 mintes into a new game the you dont have much of a chance, everyone is more tough than you.

But yes you can go to other bioms and Get lucky killing something and unlocking things in the game that you will first get at a later time but that is not how you are supposed to progress though you can.

You need to build up strength first, make armour, weapons and so on, and then upgrade or get new technology along the way.

ps. dont be afraid to setup spike defences before you summon a boss just build a workbench and build some places to hide ect.
