  1. My 14 year old western has been diagnosed with dog dementia and just recently when in the garden has started walking into the plants chairs table or trees she seems very disoriented like she doesn’t know they are there. Her sight is OK she manages indoors only bumping in to corners. We now have to be with her constantly in the garden. It is frightening for us so it must be for her my poor baby

      I’m so sorry, Lesley. She may adjust to it better than you think. But bless you for loving and caring for her so well.

        I have two dogs going through this atm, one is 18 and other is 15. Hate seeing them like this. My Springer Teal has adjusted well. My wee jrt Tobys is more recent and he seems a lot worse. It’s Heart breaking. Wish I could take it away from them. Toby seems to be really struggling with it all, whereas Teal just sleeps a lot x

          I’m sorry you are going through this with your two seniors. I sure know what you mean about making it all go away. It’s so unfair. Take care of yourself–I know you are taking great care of your dogs.

    Eileen, I’m selfish. I can’t let her go. I’m up all night with her, so she doesn’t wake the rest of the house. I hand feed her and bring her to the water bowl. I hold her for hours, trying to keep her calm. (sometimes it works) My room mate & I have had many discussions with the vet. She is a little over 20 years old, blind, deaf and has kidney disease. She is a mini dachshund. Her last bloodwork in April, showed all her numbers stable. She has had CCD for over 2 years now. She doesn’t appear to be in pain. I’m noticing, the last day or 2 she is only sleeping 1 to 2 hours at a time, whereas she would sleep 4 to 6 hours at a time. How much worse will it get? Do I kill my little girl because she is an inconvenience?
