Again awesome advice already given. I agree I would wait until he's settled in before making more changes in his routine. He will probably be a little stressed at first until he becomes adjusted to his new home, new smells, and new surroundings, plus adjusting to being without his sister and other dogs. When you do switch his food, it's best to do a slow transition to avoid stomach upset. Start with 2/3 of the old food mixed with 1/3 of the new food for a few days, then mix 1/2 of the old food with 1/2 of the new food for a few days, then finally mix 1/3 of the old food with 2/3 of the new food, then transition to just all of the new food. This will usually take about two weeks to fully transition, but is better to do it slowly so he gets used to the new food. It can take up to a month for the old food to leave his system. I usually just use a couple of pieces of their own kibble to use as a treat, or "bribe" lol. The pieces are small enough, they aren't going to cause any weight gain if you are just giving a piece or two, and it's their food, so they are used to this, so won't cause a reaction or allergies. The kinds of treats I like and buy are all natural like Benny Bully Dried Liver, the only ingredient in these are dried liver, I like the fruitables, which are also all natural, and made with fruit, and the Zekes Peanut butter treats. I also have made my own, my guys like a Tbsp of unsweetened yogurt with a tsp of peanut butter, I place it in a ice cube tray, or on parchment paper and freeze them. I also give my guys 1/2 a banana each two or three times a week, they get cut up apples, cut up strawberries,and blueberries. I also give my guys natural supplements like plain unsweetened yogurt on their morning kibble, for the probiotics, and for digestion, it is also great for the immune system due to the probiotics, I give them coconut oil on their evening kibble for the Omega fats, and I add 1 Tbsp. of apple cider vinegar to their evening kibble as well. There are many health benefits to ACV. I like these things because they are natural, have no side affects, they boost the immune system, the Omegas are excellent for the hair, skin, brain, and joints, and they are all inexpensive to buy, and can be bought at a health food store or I the organic section of the grocery store. I buy my Organic Coconut oil at Costco.
