Hi, my 6 month old boxer barks has started barking all night in her crate. She never used to bark, this just started about 3 weeks ago. For the first 2 1/2 weeks we got up each time to lt her out thinking she had to go potty, but she never went. She would just stand by the door to be let back in. For the past few nights we have just let her bark and she doesn't stop. My husband thinks maybe our 22 month old male is teasing her, he is not crated, but I don't think so. He doens't bark at night. I have been told to use a bark collar and wanted to see if anyone has used one and whether it's useful or mean. Any advise will help! Thank you!
