Feeding your puppy with a breast milk substitute in the first four weeks of life is a process that requires special attention. The most recommended option is a milk substitute, such as milk powder designed for puppies. This type of milk is similar to breast milk and has a lactose level suitable for his sensitive digestive system. In addition, the milk substitute formula is adapted to protect the intestinal flora and ensure easy digestion. Milk powder is prepared with heated bottled water, following the product's dosage instructions that you can buy from products for your dog online.
