Dog Vaccinations

Protecting Your Pooch

Sunset's dog vaccinations ensure your pooch is protected from common canine illnesses.

Our Dog Vaccinations

One of the easiest and most helpful precautions you can take for your dog’s health is to ensure he or she is up to date with the latest dog vaccinations. There are many illnesses dogs can develop that can malevolently affect various canine body systems and processes. Some are even zoonotic, meaning they can affect human health as well. At Sunset Animal Hospital, we offer four dog vaccines that, in conjunction with routine heartworm testing and prevention, are sure to allow your dog to enjoy a long, healthy and vibrant life. Read more about each of our dog vaccinations below.



The DHPP dog vaccine provides protection against canine distemper, hepatitis, para-influenza and parvo. Dogs should receive this canine immunization when they are puppies between six and eight weeks old. At Sunset, we suggest continuing this dog vaccination every three to four weeks until our furry friend is 16 weeks old since this will confidently ensure there is not any maternal antibody competition. We administer this dog vaccine one year after the last puppy shot is given and once every three years afterward.



Rabies is a deadly virus that affects the brain and spinal cord of all mammals including dogs and humans. Therefore, it is very important to protect your pet from this virus. By law, dogs must receive a rabies shot during their initial dog vaccinations they get as puppies. An adult booster shot is given a year later and administered every three years afterward.



Bordetella, also known as kennel cough, is a very common and contagious illness that affects the canine respiratory system. The bordetella dog vaccine is administered intranasally during the first puppy visit. An injectable vaccine is given three to four weeks after the intranasal dose, and then the vaccinations rotate between intranasal and injectable doses.



Leptospirosis, also known as lepto, is a bacterial disease that can affect both humans and pets. It occurs all over the world and leads to liver and kidney damage as well as death if left untreated. Humans and pets can get this bacterial infection by coming into contact with infected wild animals (e.g., possums, skunks, raccoons and rodents), lepto-infested water or infected urine. Since this disease can harm animals and humans, we encourage dogs to receive this immunization via two initial doses three weeks apart, and then on a yearly basis.



Heartworm disease is a serious condition that affects thousands of pets every year. Heartworms are parasitic roundworms that reside in the arteries, lungs and hearts of dogs, cats and other animals. Once an animal is infected, it is essential to seek treatment, or else its life will be cut short. For dogs, treatment is possible, but it is prudent to focus on preventing the virus from the start. At Sunset, we recommend having your dog tested for heartworms every year and maintain a monthly heartworm prevention regimen due to the fact that Houston is an endemic area for heartworms.



Influenza (CIV or H3N8) – Canine Influenza, or the “dog flu,” is caused by the H3N8 Virus, which is a disease of dogs (not humans). The virus is spread from sick dogs that may be sneezing or coughing, contaminated objects or people moving between infected to uninfected dogs—this means the dogs don’t ever have to come in direct contact with other sick dogs in order to catch the virus. Symptoms may be mild such as coughing, runny nose and fever or severe such as pneumonia. Puppies or adult dogs who have not had the vaccine will receive two doses 3 weeks apart after, and then one dose each year after that. For more information, click here.
