My DDog is 12. She has Canine Cognitive Dysfunction and we've just done the questionnaire again and she is now in the severe category.
I don't know how we decide when to let her go.
She has some good days (well parts of days) but then others she doesn't. She's becoming aggressive, but I don't know how to decide when it's become a real risk to us and the other pets.
I really don't know how to gauge what her quality of life is now and I feel very conflicted because she was such a darling girl and such a big part of the family, but it's like she's "gone" already due to the personality changes.
