I have two border collies… 9 months and 11 months. They’re very fickle about their protein sources… Both are intolerant of bison and venison, one can handle beef but the other cannot. Both are sensitive to changes in fats in their diet… too much fat causes them some nasty stools, but too little and they get dry and itchy.
I had them on Taste of the Wild for a long time, but they get really twitchy moving from one mix to another. I’m starting them on Acana Sport and Agility this week. I feed them half raw food as well.
Remember with borders that their metabolism tends to run hot due to their need to work and possibly work long past exhaustion. If you normally feed once a day you might want to consider twice a day for the BC.
