If I could change anything right now.

My dog just turned 5 months. I know I need to give him grace. But you all know that the first few months with a puppy feels like a lifetime. I am SO sick of the constant biting. If he’s out of his kennel he is incessantly trying to gnaw on our arms, hands, limbs, or clothes. Redirection (giving him his toy etc) works some of the time but the need to chew is just driving me absolutely insane. His teeth look like they are all in. I could see molars breaking the gums a month ago but they’re in now. You can’t even reach for him to pet without him turning his face towards you looking for which body part he wants to attack next. IWhen does this end? I’m so over it. I have kids and it’s exhausting constantly getting onto him. He’s a male miniature American shepherd for reference.
