I have a 5 month old puppy who was doing great with toilet training until about a week ago.She suddenly started acting like she did when we first got her. She is peeing in every room she goes into despite the fact that I bring her out to the garden VERY regularly. Her permanent teeth are coming through so that be an issue and she also has become very barky in the evenings. She sees herself as the leader of the pack and no matter how we discipline her she barks in defiance. Feeling very disheartened with it all at the min and not enjoying her at all. Any suggestions? She is a King Charles.
