We have to put their needs first even if it’s not exactly what we want. Sounds a bit like parenting, yeah?
Children can’t be our emotional dumping grounds - nor can our dogs. Therapists, trusted friends, family members, or mentors are great for that. But kids and dogs... not so much.
Understanding dog psychology is imperative to understanding how to properly fulfill a dog and how a happy dog looks.
Once you have that knowledge/visual, you realize that you are projecting your own personal version of happiness onto an animal that totally missed the memo on how your version of happiness is the best.
Continue to make strides in truly understanding your dog as: animal, species (canis lupus familiaris or dog), breed, then individual dog and raise her accordingly. But most importantly - surrender to the process and enjoy the journey. Raising a dog is a lifelong commitment. Learn as much as you can from them. They are the real teachers.
