Dog Vaccinations in Alhambra: Core Vaccines, Schedules, and What Your Dog Actually Needs

Dog vaccine conversations tend to produce more confusion than clarity. Some owners are worried they're over-vaccinating. Others aren't sure which vaccines are legally required versus optional. Many just do whatever their previous vet recommended without fully understanding why. This post lays out what dogs in Alhambra and the surrounding SGV actually need — by law, by medical consensus, and by lifestyle.

At South Pasadena Animal Hospital, we tailor vaccine recommendations to each dog's specific situation. We're at 3116 W Main St in Alhambra — book online or call (626) 441-1314 to schedule a wellness exam and vaccine review.

What California law requires

California state law requires rabies vaccination for all dogs. This is non-negotiable — it's a public health law, not just a recommendation. Puppies receive their first rabies vaccine at 16 weeks or older. After the initial vaccine, a booster is due at 1 year, then every 3 years for adult dogs.

Rabies is a fatal disease in both animals and humans, and the vaccination is highly effective. It's also required for dog licenses in most California counties, including Los Angeles County.

The combination vaccine every dog gets — and why

DA2PP is the core combination vaccine, and nearly every dog we see gets it. It covers distemper, adenovirus, parvovirus, and parainfluenza — four diseases you rarely see in vaccinated dogs precisely because the vaccine is so effective. Parvo is the one worth explaining: it's highly contagious, survives in soil for months, and spreads at dog parks and on sidewalks. We've seen unvaccinated puppies come in very sick after exposure at the park. The vaccine works. DA2PP starts at 8 weeks as a puppy series, boostered every 3–4 weeks until 16 weeks, then again at one year, then every three years for adult dogs.

The vaccines that depend on how your dog actually lives

Bordetella is the one most boarding facilities, groomers, and doggy daycares in the Alhambra and SGV area require. It protects against kennel cough, which spreads fast anywhere dogs interact. If your dog boards, gets groomed, goes to training classes, or runs at a dog park, this is relevant. We give it annually for most dogs, every six months for high-exposure ones.

Leptospirosis is the one that surprises SGV owners the most — they don't think of it as a local issue, but it is. Lepto spreads through wildlife urine in contaminated soil and water. Urban rats, raccoons, and possums are common enough in our area that exposure is real, especially for dogs that hike the Arroyo Seco, drink from outdoor water sources, or have yards where wildlife come through at night. We discuss it at every wellness visit for dogs with any outdoor exposure. Two-dose initial series, then annual.

Canine influenza we recommend selectively — dogs with heavy exposure to other dogs in group settings like boarding or daycare are the ones worth discussing it for. It's not for every dog. Ask us at your dog's next visit.

Puppy vaccination schedule

Puppies receive maternal antibodies from their mother that gradually wane over the first weeks of life. The puppy vaccine series is timed to provide protection as those maternal antibodies decrease:

Age	Vaccines
8 weeks	DA2PP #1, Bordetella (if exposure risk)
11–12 weeks	DA2PP #2, Leptospirosis #1 (if recommended)
14–16 weeks	DA2PP #3, Rabies, Leptospirosis #2 (if started)
12–16 months	DA2PP booster, Rabies booster, Bordetella (annual)
Every 3 years after	DA2PP, Rabies (per California law)

Some puppies need a fourth DA2PP dose at 18–20 weeks if the series started early. We'll confirm the right schedule at your puppy's first visit.

Adult dogs: do they need annual vaccines?

Core vaccines (DA2PP and rabies) for adult dogs are not given annually — DA2PP is every 3 years and rabies every 3 years per California law after the first booster. This has been the standard protocol since updated guidelines replaced older annual schedules. Lifestyle vaccines like bordetella and leptospirosis remain annual or more frequent for dogs with ongoing exposure.

Annual wellness exams are still important even when vaccines aren't due. They're the time to run bloodwork, check weight and dental health, and catch early signs of problems that don't show obvious symptoms yet. Don't skip the annual visit just because no vaccines are scheduled.

What happens at a vaccine appointment at SPAH

Vaccines at SPAH are administered during a wellness exam — not as a drive-through service. The exam covers your dog's weight, heart and lung sounds, teeth, eyes, ears, coat, and any concerns you've noticed. This matters because vaccines should only be given to healthy animals. An exam first ensures your dog is in good shape to receive them, and it gives us a chance to flag anything you may not have noticed at home.

We'll also review your dog's exposure history and lifestyle to make sure we're recommending the vaccines that are actually appropriate — not just running through a standard checklist. Our pricing page has vaccine and exam fees listed in full. Book online or call us at (626) 441-1314.
