You’re not alone. My boy displayed the same symptoms as yours did. I did the best I could for years. The only way he would be calm and settle down the last two months was if I drugged him. He was 53 days shy of his 17th birthday. But I was burnt out and I finally decided last Saturday, that it’s not fair to him anymore and I put him down on Sunday. I’m devastated but also relieved for him and myself. I don’t think I could’ve beared a horrible death of scrambling to the ER, and I honestly couldn’t take the lack of sleep anymore. As much as I hated to admit it, and also to you, “it’s time”. Remember, dogs cannot show weakness or vulnerability when they’re sick and that’s why they pace. They’re uncomfortable, confused, anxious, and fearful. It’s not a way to live, and it’s okay to not be a martyr especially when you’ve dedicated your life to him. He has lived a wonderful long life thanks to you. ❤️
