Frequently Asked Questions
When can my puppy go to dog parks?

How often should my puppy see the vet in the first year?
Minimum 3-4 visits for vaccination boosters. Additional visits for: illness, spay/neuter, and any concerns about growth, behavior, or development. Don't hesitate to call — catching problems early is always easier and cheaper than treating advanced disease.
