Is My Dog Mentally Retarded?

have a cockapoo who is one years old. She still pees in the house after I have been trying to train her for months. She isn’t crate trained even after she spends half of the day in there, she STILL barks! She chases the cat and our german shepard. Scarlett always sticks her head inside his mouth and bites him. She bites the carpet, the bottom of the bed, my books, etc. I know she is definitely done teething. She pees next to the window on the cement instead of the grass. She’s a very smart dog. (first in her class to sit, lay down, and shake.)
She goes on three walks a day and goes out to the restroom every hour! She goes to the dog park twice a week. She has plenty of chew toys. She has been to training at Petsmart.
Thanks!
By the way I’m a thirteen year old so give me a break! My mom told me to do this! I have friggin dyslexia! So maybe I spelled it wrong but get the heck over it!
(I made this post earlier and people kept talking about my i.q. instead of question.)
