Hi everyone! I really need advice on our 5 month old large German Shepherd puppy. He's scared of bathing to the point that he freaks out and tries to escape the tub. He literally screams as soon as water touches him. We're not sure if he has trauma from his previous owner but we've never seen a dog act that way. Tried petting him and talking softly but it doesn't help. Really hoping to get him more calm while he's young before he gets to the expected 100 lbs. Any advice would be greatly appreciated! Thanks!
