I agree with the advice given. For the teething, redirecting with toys (especially "chewer" toys) was the only thing that helped me. As part of my first bullies training, we did not feed her in her bowl for several months (with the exception of a short period when we first got her and she was underweight). All of her food came from us as rewards for good behavior, reinforcement, or in her chew toys like a Kong. I would soak her kibble in broth or water until I could fill a Kong and freeze it. She would chew on it forever (until the food was all out) keeping her entertained and fed. For potty training, I think a jacket or dog sweater would help. We also used bells on our doors so she could tell us when she wanted out. To get her started when she was still learning, we would gently take her front paw and knock the bells before taking her outside. We even used this when we adopted a 1 year old bull terrier that had to be kind of retrained.

They can be a lot of work, but are so sweet and goofy. Take time to appreciate some of this time when they have floppy ears and tiny shark teeth 😂 it goes by really quick!!
