Hello All My puppy is 7 weeks old. When can I start bathing him? What supplements should I give? He is a Golden Retriever. Currently I give Digyton Plus ( digestive ) and Proviboost ( multivitamins and amino acids ). Any supplements for bones, hair etc? When can I start potty training? What age can overall behavior training should ideally start? Should I brush his teeth or use mouth freshner? If so, how often?
