I bought a puppy from a dog market; I don’t know when it was dewormed or vaccinated. What should I do?
Puppies from proper kennels come with records of birth, deworming and vaccination dates; ask the seller if missing. Without records, the pup likely missed proper immunization, so do antibody and fecal parasite tests at a clinic. Revaccinate if needed and deworm per results.
What happens if a dog is given expired vaccine?
An expired vaccine generally does not seriously harm the dog's body, but it easily causes immunization failure. Vaccines are inactivated or weakened-virus types, and expired ones may lose potency, so test antibody levels 15 to 30 days after vaccination and re-vaccinate if low. Also, poorly stored expired vaccine may cause itch, redness, or swelling at the injection site, needing prompt vet care.
Can I vaccinate my dog myself?
If you know the procedure, you can vaccinate at home, but never buy vaccines from markets or online since their safety is unverified and may cause vaccine failure. Vaccines are injected subcutaneously; wrong technique harms immunity. Otherwise, go to a vet.
Can my cat’s third vaccine shot be delayed a few days?
Vaccine doses are normally 21 days apart; delaying more than 5-7 days is not advised, and gaps over 28 days reduce immunity. If a dose is missed, test antibody levels 21 days after the third shot; if low, give 1-2 booster shots.
What is a dog license (dog registration) for?
A dog license proves legal ownership and vaccination, protecting the dog from being treated as a stray. It is also required for air and rail transport. Before applying, confirm the breed is not banned, vaccinate, then bring photos to the local police station.
Does Your Cat Really Need Annual Booster Vaccines?
Core cat vaccines are the FVRCP combination and rabies. After the first series, you don't have to boost every year — titer testing can show if protection is still strong, and low-risk indoor cats may go 3 years between boosters. Always vaccinate at a licensed clinic and watch for reactions afterward.
Can Dogs Ride High-Speed Trains?
Dogs are not allowed on high-speed trains except certified guide dogs, which must be reported in advance. Other pets can travel by train shipping with health certificates arranged ahead of time.
Why is there a bald patch on my cat’s head?
A bald patch can come from skin infection or injury. Check for wounds, dandruff, itch, or redness. If no wound but dandruff, it's likely a fungal/bacterial infection — see a vet for targeted treatment. Common pathogens include Staphylococcus, Malassezia, and mites.

Should You Test Antibodies After Vaccinating Your Cat?
Antibody testing after vaccination confirms the vaccine worked. A normal titer sits between S3 and S5; below S3 means the cat is not protected and needs a booster. Test about 15 days after the final shot, and avoid baths or outings right after vaccination.
What documents are required to register a dog license?
You need two 2-inch photos, household or residence proof, ID with copies, and a vaccination certificate from an animal health authority; guide dogs need a disability certificate. Submit at the local police station.
