No, have considered and researched this option thoroughly and it is just too much work/time for too little reward. We could make a milk cow out of a Highland as they are sometimes used for this purpose, are generally very tame, gentle cattle if raised properly, but I follow a mix of mostly Paleo/Ketogenic diets which allow unlimited meats (as long as they are not processed meats especially not including sugar such as ham and bacon, though non-sugar-cured bacon is allowed so we can make our own healthier bacon and ham once we have pigs) and organic produce but no grain and very little dairy. We consume almost no dairy and never any milk, no kids here just two adults and dogs, so it would be way more trouble than worth to have a milk cow just to produce the tiny amount of butter, cheese, etc. that we do eat plus then we'd have to find buyers for our surplus milk (though skim milk is excellent as a pig food supplement), much more cost-effective to pay extra to buy grassfed, antibiotic and other drug-free butter and cheese from stores/farmers markets in the small amounts we use. Goal is to supply all of our meat and produce needs and only use grocery stores and other food sources for the small amount of high quality dairy products we consume, only from grassfed organic cattle of course, and occasionally to treat ourselves to things which are healthy but we can't or haven't yet been able to produce at home.
Valium does the same for me. Maybe wolf berries are a natural source for this pharmaceutical miracle drug.
Kidding of course. I have PTSD and am prescribed Valium/diazepam for that and without it I can't get any kind of decent sleep.
Obviously it's your choice, but I hope you will someday research what is in those cheap bags of "dog food" and decide to feed them something better.
