Animated 80s movie - wolf pack attacks family, Family hides in Farm/wooden house

I saw an animated movie from 80s I guess or older about a Family living in a wooden House in the forest / on a Farm and getting attacked by a Wolf Pack. First they Encounter a small number of wolves and they fight them away by the father and his gun but later the whole pack arrives and the Family hides inside the House. Maybe it is snowing and maybe a fire Breaks out.

Does somebody know what movie that was? Thank you much in advance

It sounds a lot like the Further Adventures of the wilderness family but that is not animated. I will keep looking.
