My chihuahua is nearly 6 months old. She has been going to doggy day care once a week for 4 weeks now and I have noticed her starting to bark a lot more since. She would rarely bark prior to the past couple weeks and people would comment in surprise at how quiet she was. I’ve seen a big improvement with her socialisation to other dogs since going to doggy day care but I have concerns that the barking may progress into an unmanageable problem. Is this part of her maturing? Could she be picking up bad habits from other dogs? Are there any other methods of training her to not bark other than saying no and firmly holding the lead or collar? I don’t mind if she barks as a guard dog when she hears someone arrive or loud noises outside, it’s more the barking at other dogs in public when she wants to play that is what I would like to correct. Thanks!
