Yes I think your right Demi.
Perhaps just stick with the simple stuff for the minute.
Sitting, walking and socialisation.
TBH Bailey was an arrogant little so and so for months....I think she eventually got the sit command when she was 6 months old. I took her to obedience training and followed through with everything they recommended. She just wouldnt! Even treats wouldnt work.
But with lots of persistence we got there.
Bailey is not perfect either we are still dealing with her aggression/timid issue towards large men and strangers but it is SLOWLY getting better.
Lots of persistence hun (hugs) and dont worry about what others think yoou do what you think is best for her. Ignore the rest.
Also be very STRONG towards others about how you expect them to be around her. This is hard.
I had trouble with people ignoring my requests and feeding her at the table and praising her for aggression towards strangers. THIS IS NOT ON! you need to be really firm about this so it doesnt happen
Best of luck hun...
