    I am not quite sure if my Yorkshire terror has this he is 10years old and started last week to keep waking up in the night he sleeps in with me and my husband and he goes over to the door and does a bark to wake us up and when we go to the door he jumps back on the bed this morning when we were still being woke up at 4.30 my husband picked him up and carried him downstairs to put him out the garden he then settled he has started wanting a drink through the night which he hasn’t done before and he is panting a bit he now sleeps more in the day me and my husband are so tired as we both work long hours this is why I thought I would check the Internet today to see if dogs can get dementia

      Sounds like a good time to talk to your vet about it. I hope you can get him settled down and you can all get some rest. Not to mention some good times.

    These stories are breaking my heart. My Khloe is my baby, a part of my body most of the time. She also has every symptom of CCD. I guess im just hoping its not that. Hers is much like sundowners same time of evening shes just not my baby anymore. Pacing, starring off into space, hiding under couch, not answering to her name and the most heartbreaking one is she wont give her momma kisses. Hers is 12 hrs on 12 hrs off. It started about 8 months ago, lasted a few weeks then she was fine, then a couple months ago same thing, then fine again til last night. Its breaking my heart, if she goes away and dont come back to me, it will be devastating. Any recommendations that can help before she stays in this horrible state? Thanks so much for letting me vent.

      I’m so sorry this is going on. I think the hardest thing is if their relationship with you changes. It’s so not fair–to them or to you. Have you talked to your vet about it? There are meds that can help a bit. Take care.
