My friend has a similar problem. They live on a farm, vaccinated their own dog and cannot prove vaccination thus no dog groomers will cut her hair. Parvo... you can kill Parvo with colloidal silver I've saved at least 1 dog from dying from Parvo with Colloidal Silver. Vaccines for animals... I'm looking at the same way I look at any vaxx these days. With a heavy dose of scepticism.
