Well, by law I'm required to keep his rabies updated, so he'll get that every 3 years because the vet uses a 3 year serum.
I watched vaccinations give my shih tzu growing up countless health problems that slowed when we stopped vaccinating, but by that point they were chronic and he had to be put down. Those things were paw-licking and chewing, skin allergies, a tumour at the injection site, and seizures.
My dad's dog had the same foot licking problem which disappeared about 18 months after her last vaccine.. My mom's shih tzu has developed a chronic skin allergy which the vet says is likely from the vaccines.
The current research says that aside from rabies other vaccines last about 7 years, some of them for the entire life of the dog. Just like people. We get vaccinated for measles, mumps, and polio when we're children but never again because they last all our lives. Why shouldn't it work similarly in dogs? It does, it's just that nobody thought to check until recent years.
And finally, most vaccinations are packed into one serum so that they only have to give one injection. Most of these vaccinations will not apply to every dog because not every dog is exposed to the same things. Why over-expose our dogs to the diseases and viruses in the serum, if they're not even going to encounter the things in real life? Unless the dog goes to shows or competitions, it's unnecessary.
Kaiser doesn't have a single one of these health problems to date, and I refuse to knowingly expose him to them. Rabies I'll keep up with because it's law and because research shows that it really does only last about 3 years. Other than that, in my opinion, it's not only unnecessary but dangerous to my dog's health..
It's a decision everyone has to make based on their own thoughts and the things that they know their dogs are exposed to. I made my decision with the help of my vet, but most vets can't be trusted to tell you yearly vaccinations are not needed because that means a fall in their income as you're not paying for those shots every year..
That's why Kaiser won't be vaccinated (except rabies) again..
