AND of course there was the rush to buy puppies during lockdown which also stretches vet's time.
However, to those of you who are vaccinating annually, you might want to rethink.
The World Small Animal Veterinary Association (WSAVA) guidelines are to give core vaccinations - Distemper, Hepatitis, Parvovirus - every 3 years.
Leptospirosis is a bit like the flu vaccine. It's advised annually BUT it often doesn't last for 12 months, and it only covers 2 strains. Some vaccines (Lepto4) cover 4 strains but there has been a lot of bad reactions, I personally wouldn't use it on my dogs. Also, Lepto is easily treated with antibiotics if caught soon enough. The ONLY reason my dogs are vaccinated for Lepto is because boarding kennels have to have proof - because the council tells them to!
So, give the vets a breather, don't stress on vaccines. Leave them to do the more pressing stuff.
