The Grey wolf we see today is of average weight between 80-150 pounds for a male and 60 - 100 pounds for a female...it's only an average..wolves in the wild can live up to 16 yrs.
Depending on region and pressure and food source much larger wolves can be found..that's a given.
I have actively trapped over 40 yrs..even though the return is greatly reduced compared to when I started and have harvested wolves at both ends of the spectrum of weight and ages.
I regularly turn in jaw bones and other materials for testing and the biologists, give me a rundown on the approximate ages and I weigh the animals..this is more for my edification than anything.
So when I say easily weigh 80 lbs plus, I kind lump all the ages and male and female averages together...I do have to type this out and I am not writing a white paper for peer review...which the majority of the posters here would find overly boring.....
