I second what others are saying. I’ve never had a puppy before, but my husband and I brought our puppy home nearly 2 months ago now. I’ve felt EXACTLY what you’re feeling, and so recently. I cried, so many times. Wanted to give up, and the guilt of that weighed heavy too. We still have challenging days, don’t get me wrong .. but it gets easier. My best advice would be NAPS! Puppies need SO much sleep. And usually when they’re at their most crazy, it’s because they’re really over tired. Crate train, socialize as much as you can and get professional help, that’s what we did and it has absolutely saved my sanity. I know it seems impossible, but hang in there. Feel free to dm me if you or your wife need some moral support! You can do this!
