Police and civil prefects. 1  Praefectus urbi, or praefectus urbanus: city prefect, in charge of the administration of Rome. 2  Praefectus vigilum: commander of the Vigiles. 3  Praefectus aerarii: nobles appointed guardians of the state treasury. 4  Praefectus aerarii militaris: prefect of the military treasury.
Puppies normally get their first shots around 8 weeks old, but they can be given earlier if needed (ie with stray, abandoned pups or those who were formula fed). Three sets of combination vaccinations (a shot that protects against more than one disease) given at 3 week intervals. 8 weeks - first round.
If you are referring to walks as times to go outside to eliminate, given your pup's age and small breed status, I'd recommend you take him out *at least* every 4 hours. When he does urinate/defecate, praise him!!! This will reinforce his eliminating outside.
