Not sure how much a song dog can eat but they rarely come solo.
Watched pack of 7 kill a pronghorn doe in Montana Ran a herd of about 20 speed goats into a fence the one they got did nto get caught in the fence but hit it hard, the others cleared the fence.
Not telling how many ate 2 pigs that were about 75lbs each that I shot one afternoon then killed 2 yotes same place the next morning. There was lots of yote tracks in the snd but nothing findable of the pigs. One of the yotes was by far the heaviest I have ever killed weighed 45lbs I bet 5 lbs or more was pork in the gut.
