Is it good to have a Sheltie after 1 year of age? The Sheltie is good to have after 1 year of age. This is a time when the schnauzer is healthier and more developed, and rarely suffers from diseases such as microcephaly and distemper, so it is better to keep. The only bad thing about the Chenery after 1 year old is that the previous habits have been formed and it will be difficult to change them. The owner has to have the patience to teach the dog and let the dog accept you slowly. This is a long process.
