      The bug

      Changing the generic.attack_damage attribute of a tamed wolf does not appear to have any effect. Similarly taming a wolf with a custom generic.attack_damage attribute value changes it to the default.

      This does not affect the Strength potion effect in the latest game versions when applied with potions or /effect; summoning a mob with ActiveEffects is MC-32575.
      See MC-193202 for the health of a wolf resetting.

      Reproduction steps (modifying attribute)

      1. Summon a wolf
      2. Tame it
      3. Change its attributes 
        /data merge entity @e[type=wolf,limit=1] {Attributes:[{Name:generic.attack_damage,Base:20.0f}]}
      4. Let it attack an entity (by punching that entity) or inspect its NBT data 
        /data get entity @e[type=wolf,limit=1,sort=nearest] Attributes

        It has the default generic.attack_damage

      Reproduction steps (taming wolf with custom attribute)

      1. Summon a wolf with a custom attribute 
        /summon minecraft:wolf ~ ~ ~ {Attributes:[{Name:generic.attack_damage,Base:20.0f}]}
      2. Inspect its NBT to make sure it has the custom attribute 
        /data get entity @e[type=wolf,limit=1,sort=nearest] Attributes

        It shows the custom attribute

      3. Tame the wolf
      4. Let it attack an entity (by punching that entity) or inspect its NBT data 
        /data get entity @e[type=wolf,limit=1,sort=nearest] Attributes

        It has the default generic.attack_damage
