Called the vet to book an appointment, I don't know why the vet chose C3 last time at 8 months, found out later C5 is recommended, price difference is negligible, especially when interactions with unknown dogs are expected, i.e. going to dog parks.
Anyway, want to make sure to go for C5 this time, then the vet offered C7 for not much more. I then called another vet, he said C5 is more common, but C7 is also beneficial.
Got me confused, there are all kinds of vaccines out there, sure everyone of them carries some benefit, but it's impractical to get all the shots.
What started out as a 3 minutes phone call got into 2 hours rabbit hole researching C5 vs C7 pros and cons.
Just throwing the question out there, do you get C5 or C7 for your dog? Obviously only a vet can give a scientific answer.
C11, 4x better than C9
