Dog vaccination
What vaccines does my dog need?
Why is it Important to Vaccinate Your Dog?
Vaccinating your dog is one of the best ways to protect them from serious, and sometimes fatal, diseases. Vaccines teach your dog’s immune system how to fight off certain viruses and bacteria, so if they ever encounter the real thing, they’re much more likely to stay healthy.
Vaccinations also help stop the spread of disease in the wider dog population, keeping all dogs safer.
Core Vaccines for Dogs
There are some essential vaccines that every dog should have, whether they’re a puppy or an adult. These are known as core vaccines, and they protect against highly contagious and potentially deadly illnesses:
Canine Distemper Virus (D) Affects multiple organs and can be fatal. Given during the puppy course and then every 3 years.
Infectious Canine Hepatitis (H) Affects the liver, kidneys, and eyes. Given at the puppy stage and then every 3 years.
Canine Parvovirus (P) Highly contagious, causing severe vomiting and diarrhoea. Part of the puppy course and repeated every 3 years.
Leptospirosis (L) A bacterial disease that can damage the liver, kidneys, and other vital organs. Given during the puppy course and then annually.
Note: Some vaccines, like those for Leptospirosis, come in different combinations to cover various strains.
Vaccination Schedule for Dogs
Vaccination Schedule for Puppies
First vaccines are usually given between 6–8 weeks of age
A second dose follows 3–4 weeks later
A booster at 12 months helps build long-term immunity
Then, annual boosters or 3-year boosters depending on the vaccine
Vaccination Schedule for Adult Dogs
Follow-up boosters will depend on which vaccines they received as puppies
Leptospirosis: yearly
Distemper, Hepatitis, Parvovirus: every 3 years
Vaccines for Travel for Your Dog
If you’re planning to travel abroad with your dog, or return to the UK, you’ll need a Rabies vaccination. This is a legal requirement and is usually valid for 1-3 years, depending on the specific vaccine used. Additional requirements may apply depending on the country you are travelling to or from, so always plan well in advance.
What to Expect at a Dog Vaccine Appointment
Here’s what to expect during your dog’s visit:
- Full health check by the vet
- Chat about your dog’s lifestyle, health, and any concerns you have
- Vaccination given via a quick injection, usually at the back of the neck
- Short observation period afterwards to monitor for any reactions (most dogs are absolutely fine!)
Dog Vaccines: Possible Side Effects
Most dogs handle vaccinations really well. Some mild, short-term side effects can happen, including:
- Tiredness
- Mild fever
- Tenderness or swelling at the injection site
- Eating less than usual
These usually go away within 24 hours. If your dog still seems unwell after a day or two, give your vet a call.
More serious reactions are rare, but it’s important to know the warning signs. Contact your vet immediately if your dog shows:
- Fainting or collapse
- Ongoing vomiting or diarrhoea
- Difficulty breathing
- Hives (red, itchy bumps)
- Swelling of the face, nose, eyes, or throat
Protecting Unvaccinated Puppies and Dogs
If your dog isn’t fully vaccinated yet, it’s important to be cautious:
- Avoid places with lots of dogs (like parks or kennels)
- Don’t let them sniff or interact with unknown dogs
- Carry young puppies when outdoors, or use a secure puppy carrier
- Keep their environment clean and free from potential infection risks
- Make sure other dogs in your home are vaccinated
Vaccination is the safest and most effective way to protect your pet in the long run.
