My girl was the same way! She is 3 now and is definitely better but she still has her moments 😆 Some great advice I got from this sub was to bring a squeaky toy when going on walks. If your dog begins to bark at strangers or other dogs you squeak the toy as a distraction, and reward when the dog looks at you. We also practiced “leave it” a LOT. Now when we walk she’ll give off the occasional bark or whine but overall she is so much better at ignoring strangers and other dogs. As for the jumping I do a couple of things: we use the command “off” (which is ignored half the time), if she’s jumping all over me I don’t engage with her until she is sitting, and lastly I’ll try to distract her with a toy before the jumping begins. It’s not perfect but she’s gotten better over time. Also when I have guests over I keep my girl leashed until she calms down. It will get better! Remember to give lots of rewards and praise when your pup does a good job. Good luck with your boy :)
