Compare Canine Spectra 9 and Trucan DAPPI+L4 vaccines on coverage, age requirements, and cost to find the right 5-way lepto combo for your dog.
Quick answer
Choose Canine Spectra 9 for broader viral coverage and an earlier start at 6 weeks, or Trucan DAPPi+L4 if you prefer a single-dose multi-pack for older puppies and need four Leptospira strains.
Core coverage differences
Both vaccines protect against distemper, adenovirus types 1 and 2, parainfluenza, parvovirus, and four Leptospira strains (canicola, icterohaemorrhagiae, grippotyphosa, pomona). The key difference is that Canine Spectra 9 uses Parvovirus Type 2b, while Trucan DAPPi+L4 uses a modified live parvovirus component. Neither covers coronavirus or other non-core agents.
Age requirements also differ: Canine Spectra 9 is labeled for puppies 6 weeks and older, whereas Trucan DAPPi+L4 and Nobivac 1-DAPPv+L4 start at 8 weeks. If you have a very young puppy, Spectra 9 gives you a two-week head start on protection.
Pack size and cost considerations
Canine Spectra 9 is sold as single-dose vials, making it ideal for small clinics or owners vaccinating one dog at a time. Trucan DAPPi+L4 comes in a 25-dose pack, which is more economical per dose if you have multiple dogs or run a kennel. The Nobivac 1-DAPPv+L4 also comes in a 25-dose pack at a similar price point.
Single-dose formats cost more per dose but eliminate waste. Multi-dose packs require refrigeration and must be used within a short window after opening. If you only have one or two dogs, the single-dose Spectra 9 may be more practical.
Trade-offs at a glance
- Start age: Canine Spectra 9: 6 weeks. Trucan DAPPi+L4 and Nobivac 1-DAPPv+L4: 8 weeks. Spectra 9 is the only option if you need to vaccinate a puppy under 8 weeks.
- Pack size and waste: Spectra 9: single dose. Trucan and Nobivac: 25-dose packs. Single doses cost more per vial but avoid leftover vaccine. Choose Spectra 9 for one or two dogs; choose Trucan or Nobivac for multi-dog households or kennels.
- Parvovirus strain: Spectra 9 uses Parvovirus Type 2b. Trucan uses a modified live parvovirus (strain not specified in catalog). If you want the specific Type 2b strain, Spectra 9 is the clear choice.
Vaccine facts at a glance
- Canine Spectra 9 Way Combo Dog Vaccine Single Dose: Canine Spectra 9 Way Combo is for healthy dogs 6 weeks of age or older and includes Parvovirus Type 2b. You can start vaccinating puppies two weeks earlier than with Trucan or Nobivac, and the Type 2b parvovirus strain offers broad coverage.
Canine Spectra 9 Way Combo Dog Vaccine Single Dose - TRUCAN DAPPI+L4 Vaccine 25 x 1 Dose: TruCan DAPPi+L4 uses modified live distemper, adenovirus, parainfluenza, and parvovirus, plus killed Leptospira bacterin for four strains. The modified live components typically stimulate a stronger immune response, but the vaccine is only labeled for dogs 8 weeks and older.
