What do you think about me adopting a dog without my husband's permission?
Is there a specific reason why you want to adopt a dog without your husband's permission?
I want one and my husband is so annoying with his stupid rules all the time.
Adopting a pet like a dog is a major responsibility and requires everyone in the home to agree on it and be ready for it. It's rude and inappropriate to unilaterally decide that you are adopting a pet and not get any input from your spouse since your decision will affect him. You should talk with your spouse and the rest of your family about adopting a dog and only proceed if everyone agrees.
But I'm always right, so I can do whatever I want.
Getting a pet without consulting with your partner will create tension in your home. It's best to be sure that everyone is okay with the added responsibility.
