Due for Booster shot

Both Porsche and I ar due for our yearly booster but mummy had not fix appt to bring us to the vet yet. She seems to be so busy these days and always so tired when she gets home. She is working later and later and spending lesser time with us. Only weekends she possibly be with us for longer hours but someimes she goes for her back therapy. Hiaz... when will we have more quality time with mummy.
