So DB and DSIL have a 13 year old dog who I recently minded whilst they were away. DDog sometimes struggles to stand back up after lying down and does have lumps that the vet supposedly believes are not worth operating on due to her age. DDog did have an operation a few years ago on something (not too sure of what) that would have killed her if left untreated.
Whilst minding her she slipped and couldn't walk for a week although the vet said it wasn't broken. This has left her mobility worse than what it was. Along with the fact that although she isn't incontinent, she's started to urinate indoors, DB is planning on taking her to the vet as he feels it's not the best quality of life for her anymore.
I suppose my AIBU is would a vet put down a dog for the reasons above? I've told DB that I don't think it's fair unless necessary and they should see her through her old age but don't want to seem like I'm sticking my ore in.
