Pfizer spun off its animal health business into Zoetis. Zoetis’ dog vaccines are more comprehensive than Merck’s, especially the Weijiaba vaccine, which prevents the most types of dog infectious diseases in China. Vaccine, and currently on the Chinese market, the only vaccine that can prevent canine coronavirus disease has received official approval from the Ministry of Agriculture of China is the Weijiaba vaccine. As for Merck’s dog vaccine, the scope of prevention is relatively small. If you want to give your dog more comprehensive protection, you have to vaccinate with multiple vaccines. The dog will also suffer from the injection, so it is better to get it right with one shot. The dog vaccines produced by Zoetis have been officially approved by the Ministry of Agriculture of China and are all regular vaccines. Dog owners can safely choose the Weijiaba vaccine, but they must go to a pet hospital to get it! Also, don’t forget the rabies vaccine. Zoetis’ Rebic vaccine is also very good. It is not easy to cause adverse reactions when given to dogs together with the Weijiaba vaccine.
