Hey everyone, So I got my puppy about a month ago from boyfriend. When i first got him he was 11 weeks and boy was he stinky. I just assumed that its cause he's a puppy I know that puppy skin dries out when you give him a bath. so as soon as he turned 12 weeks I gave him a bath. Every part of him smells fine except his ears! is that common for a yorkie ? if so can we clean it ourselves or am I going to have to take him to a groomer? and is it common for him to shake. he shakes sometimes I dont know if he's cold or if he's scared. he shakes when there are unfamiliar people are around and when he's a couple of feet away from me. he's probably about a 1 lb and 8 oz and 13 weeks is it common for a small dog to shake like this? thank you for any advice!
