I've been slowly adding supplements to my dogs' kibble each day, and about 6 weeks ago I started addeding a scoop of plain, unflavored yogurt with live cultures. It occurred to me tonight that Angel has not released her toxic amnesia gas in several weeks. I know dogs are lactose intolerant, which theoretically the live and active cultures should be breaking down the lactose. I am thinking that Angel's lack of farting means that she's tolerating the yogurt well. Is there a risk of making a scoop (< 1/4 cup) of yogurt a daily supplement? Should I watch out for anything to alert me to them not tolerating it? I'd assume runny poops and bad gas, but I'm not seeing that.
