Lymph is a fluid that circulates throughout the body in the lymphatic system. It forms when tissue fluids/blood plasma (mostly water, with proteins and other dissolved substances) drain into the lymphatic system. It contains a high number of lymphocytes (white cells that fight infection).
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.
A second vaccination is recommended after 1 year, then boosters every 3 years. Core dog vaccine. Distemper. At least 3 doses, given between 6 and 16 weeks of age. 2 doses, given 3-4 weeks apart. Puppies need a booster 1 year after completing their initial series, then all dogs need a booster every 3 years or more often.Core dog vaccine.t least 3 doses, given between 6 and 16 weeks of age. 2 doses, 3-4 weeks apart.
