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.
Age isnât the only thing to take into consideration when determining when puppies can be removed from their mother. While 6 weeks is a standard age, maturity should be taken into consideration, as pups learn acceptable behaviors by playing with litter mates. For example, puppies teach one another when a bite is too hard and they learn to establish hierarchy within their pack. Allowing pups to remain together, with their mother, for as long as 10 weeks, can help to reduce the potential for behavioral problems down the road. A mother dog will help make the determination of when pups are ready to be weaned from her by spending more time away from them and encouraging their independence.
A brother and sister from the same litter can create their own litters by the age of five months. It is not a good idea to allow this to happen. Mother cats or dogs can become pregnant while nursing. It is important to keep a nursing mother away from other adult cats/dogs of the opposite sex. One can spay a mother as soon as the kittens or pups are weaned, (5 to 6 weeks for kittens and 4 to 5 weeks for puppies) and because of the risk of pregnancy this should be done.
