Not sure how old yours is but definitely recommend training ASAP! Not for the tricks so much but just the concentration and focus on you. My Cockapoo was an absolute bloody nightmare, frankly none of us could stand her for weeks but she was a new dog post-training! She found a new respect for us as her owners I think, it taught her who was the boss and what she needed to do to get praise. She still has her moments (now 15 months) but it does get better I promise. Hang in there it’s worth it I promise x
