Hi, I have 2 EB's, a male and a female, they are litter mates, and are 14 months old, their names are Bulldozer and Blossom. My female Blossom has a lot of allergies or sensitivities to chicken, salmon, grains and corn. They came from the breeder on Royal Canin, and we had a lot of problems with hives, red face, ears, chin and itchiness, plus soft serve consistency of their poops. We switched them to Go Natural, holistic organic food, which I was familiar with and liked, butbitvwas too rich for Dozer, and he started to eat his poops. YUCK. Blossom didn't tolerate it because like the Royal Canin, it was a chicken based food, we switched them again at 6 months old to the Fromms Beef Fritatta, and they have been great ever since. Their poop regular, and they are soft but firm, and their poops don't smell as bad, don't get me wrong, they still smell, it is poop after all. Lol. We also give them 2 Tbsp of plain unsweetened yogurt on their kibble in the morning, we add apple cider vinegar to their drinking water every day, and we add salmon oil to their evening meal. All these things boost their immune system and aid in digestion and give them probiotics. They are all natural supplements so will not harm them. We add 1/2 a cup of warm water to the kibble as well as this softens their food a little, and I find they don't always drink enough water, so this ensures they get enough water. Could the milk or cottage cheese be upsetting his stomach? Sometimes dogs don't always digest or tolerate dairy products very well. Yogurt is the exception as this has probiotics and aids in digestion and is usually tolerated well. It could be the switching, or the dairy products, or it could be a intolerance to the food, especially if it is a chicken based food. You could try switching him to Fromms, with a slow transition and keep adding warm water to his food, to make it softer for him, try eliminating the milk and cottage cheese for now to see if it makes a difference. It's trial and error and can be frustrating when trying to find a good food that our babies can tolerate, but once you do, you'll see the benefits and results. Good luck, I hope you find one that works for you. Keep us posted.
