Ex Input:
I was expecting a very high quality coffee but this wasn't quite it. It's a lot stronger than I was expecting due to the serving size printed on the label. It was pretty strong even for me and I like strong coffee.  However, I adjusted the amount of coffee and after a couple of tries I got a nice pot. It has good, but not great flavor. Definitely better than Folgers and the like but not top tier quality.  I recommend this to anyone looking for something a step up from Folgers.

I have three Newfoundlands so we go through a lot of food!  One of the dogs has had severe health issues and since we've switched from commercial kibble to home made food, he's thrived!  He gets regular blood tests to monitor the drugs he's on and they have been perfect since we started on Sojos!  It will not cure his issues, but he has more energy and he can't wait for meal time!  The other two are glowing with health as well!  All three dogs coats are shiny and they have tons of energy (for a Newf!)

A few years back, prompted by the death of one of our dogs due to an inoperable brain tumor, I switched my dogs to foods without corn.  I was convinced, right or wrong, that my animal died needlessly because of an over usage of steriods prescribed to cure her constant ear infections.  I believe, again right or wrong, that the recurring ear infections were caused by an allergy to corn...which turned out to be the main ingredient in her food!  Sorry, I'll get off my soapbox and address the issue at hand...I found this food by accident.  The only type the store had was the weight loss formula.  Turns out my dogs love it!  I haven't seen them so spunky and full of energy.  I've got a coon hound and two jack russells (mine are not the "bounce off the wall kind", mine are mellow, laid back kinda dudes!)  They gobble this stuff up and seem to stay full...no more begging in the kitchen than normal! Everyone's skin seems smoother, eyes are brighter, heck, I think I'll go have a bowl!  All I can say, is if you are looking for a good quality dog food, this is the one for you.  YOU WILL NOT BE DISAPPOINTED!
