Marshfield Veterinary Service knows that welcoming a new puppy or kitten into your home can be exciting, but overwhelming. At your first puppy or kitten visit, an experienced technician or assistant will go over concerns that you may have about diet and exercise, housebreaking, behaviors, vaccines, flea and tick prevention, as well as parasite control. We can begin vaccines at 8 weeks of age with most vaccines needing a series of boosters.
