How old is Maya? Puppies should not go to grooming salons, pet stores or puppy classes until they have had their full set of shots plus two weeks for full immunity. Shots should not be started until they are 9-10 weeks old. Any earlier and the maternal antibodies she got from nursing just kill the virus in the vaccine and leave her completely unprotected from dangerous disease like parvo. Parvo lives on surfaces for months and kills all too many puppies, even puppies who have two out of three shots.
"In one study of a cross section of different puppies the age at which they were able to respond to a vaccine and develop protection covered a wide period of time. At six weeks of age, 25% of the puppies could be immunized. At 9 weeks of age, 40% of the puppies were able to respond to the vaccine. The number increased to 60% by 16 weeks, and by 18 weeks of age, 95% of the puppies could be immunized."

Purina is a terrible food. All the food you find in the grocery store is made form the waste of the human food industry, the not-fit-for-human-consumption byproducts.
