Water & Nutrients. Like humans and animals, plants need both water and nutrients (food) to survive. Most all plants use water to carry moisture and nutrients back and forth between the roots and leaves. Water, as well as nutrients, is normally taken up through the roots from the soil.
Changing from puppy food to adult food depends on the size of your dog as an adult. If he is a small breed and will not exceed 30 pounds, he is mature at 10 to 12 months old. Some small breeds are mature before 10 months of age. Medium breeds are dogs that do not exceed 80 pounds at full growth.
Hereâs a simple fourâday guide to help make the switch to adult dog food as seamless as possible: 1  Day 1: Fill your dog's bowl with approximately 75% puppy food, 25% adult food 2  . Day 2: Fill your dog's bowl with approximately 50% puppy food, 50% adult food. 3  Day 3: Fill your dog's bowl with approximately 25% puppy food, 75% adult food. Day 4: Fill your dog's bowl with 100% adult food. If your puppy doesnât seem to be transitioning to the new dog food, consider switching the formula type (from chicken to salmon or lamb, or vice versa).
