I don't have much to share in the way of LIFE ALTERING changes since we started raw full time almost 2 years ago.
But I have to say, I do not miss the mastiff's awful, rancid gas.
Dozer would fart some of the worst gas. It was so bad we would actually want to leave the room. This happened on a fairly regular basis and I thought it was just him, that we would have to deal with it for his life time because he was a mastiff or he had digestion issues (despite healthy clearances from the vet).
Some kibble gave him worse gas than others. We tried Merrick's Whole Earth Farms kibble which was a decently priced "holistic" formula and the smell permeating from my giant dog's rear was life threatening.
Today, I sometimes forget about those early days of nasal assaults. Why? Because Dozer never farts on the raw diet. If he does, they have no smell to them. He only ever has stinky ones when he is on medicine (for example, he had to have a skin tag removed from his eyelid requiring antibiotics). When I think about how I thought his gas was something we were just going to have to live with, I have to laugh.
Other changes would be smaller poops, better teeth (although I did notice that Dozer chipped a canine tooth on either a deer leg or spine so we are going to avoid these in the future), better breath, and happier dogs. My dogs were NEVER as excited about kibble in their bowls as they are now when I prepare their meals.
I am sure their healthier diets are doing wonders for them that I can not see as well.
