We have a dog. We are in trouble by our dog recently. Because our dog keeps on barking in the middle of the night. My dog is very clever and gentle. Normally she doesn't bark. But nowadays, she's changing. She's so noisy. Maybe it's because she's getting older and senile. We couldn't sleep last night. My dog keeps on barking from 3 am until in the morning. My husband took a walk with our dog three times in the middle of the night. My dog got sick last year. We took care of our sick dog. We worry about our dog because she almost dying. And my husband found a dog chain necklace for Rena. And we bought it. It is \18,000. It was too expensive. I put on the dog chain necklace on Rena's neck and then she was fine from that time. Unbelievable!!! She is fine now but she just getting senile.
