We get vaccinations yearly, rabies every 3. The vaccinations are required for therpay dogs (unless you do titers) also weel as the dogs parks and dayschools we go to. Our dogs are literally exposed to 100's of different dogs each year and I think it is too risky to not vaccinate. Maybe whenthey get older and aren't out as much we will cut back, but for now, I think we are better off vaccinating.
