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.
At 4 months being a large breed puppy he probably SHOULD be eating adult food. The puppy food can be too high in protein and calcium and can cause their bones to grow out of whack resulting in hip dysplasia or other painful ailments. Another good thing to keep in mind is to keep him on the lighter side.e eats... show more is it ok for puppies to want dog food for adult dogs... i have 2 dogs, gia marie is 3 years old and rascal is 4 months, when i feed them rascal will eat some of his food then sit by gia and catch whatever food she drops and waits until she finishes to eat some of hers...
