Vet Q & AShould I buy a harness before or after getting my 8-week-old puppy?
i would wait until you get the puppy. Even if you cannot take him with you to the shop ( he will not have all his vaccination at the age of 8 weeks), you could try the harness at home, and if necessary return or exchange, if it is not comfortable for Theo.
