I got my oldest yorkie,Lady,at 7 weeks old.She was wonderful from the start and by 16 weeks old she was going on her pad 100%.I thought I was SO lucky because I had heard about how difficult it is to train this breed.Then I got my second yorkie when Lady was 7 months old and her potty habbits went down the drain

She is 14months old now and will NOT use her pads unless we take her to them and sit her there until she pee´s.She will go all over the house

She poops at our feet and pee´s in secret corners..its just terrible! Jessie,my youngest yorkie is wonderful with her pads..she is totally trained and no trouble at all.
I guess some yorkies just go through stages..in Ladys case,shes not getting over it! lol.
