Why dont you go to the Government Animal clinic. I have had my cats done there. The clinic is located on a'port road towards Wakrah. After the first traffic light get onto the slip road. The clinic is the last building (beige) before the next traffic light. Go into the very small road between the buidlings and then turn left into the parking. Go arounsd to the opposite side of the building. Entrance small animals. and Presto. The clinic is open Sunday thru Thursday from 7am till 1pm. The best thing, it is free of charge. The doctors are very friendly, not too many have good english. But if you say rabies and point to your dog.
However I do not know if they have that particular brand though. But is it important?
